How to change Assembly Version Number using AssemblyInfoTask? - msbuild

I am trying to automate the process for setting the Version for all DLL's, after spending some time I came to know the AssemblyInfo Task with which it can most likely be achieved.
So I went ahead and installed it, specifically version 1.0.51130.0.
After Installing, I manually added the Import Tag (by unloading the each project) of AssemblyInfoTask in .cspoj files (the solution has more than 35 proj files).
<Import Project="$(MSBuildExtensionsPath)\Microsoft\AssemblyInfoTask\Microsoft.VersionNumber.Targets"/>
Next I modified the Microsoft.VersionNUmber.Target file which will be installed in path: C:\Program Files\MSBuild\Microsoft\AssemblyInfoTask, and I modified the following section:
<!-- Properties for controlling the Assembly Version -->
<PropertyGroup>
<AssemblyMajorVersion>4</AssemblyMajorVersion>
<AssemblyMinorVersion>0</AssemblyMinorVersion>
<AssemblyBuildNumber></AssemblyBuildNumber>
<AssemblyRevision></AssemblyRevision>
<AssemblyBuildNumberType>DateString</AssemblyBuildNumberType>
<AssemblyBuildNumberFormat>01MMdd</AssemblyBuildNumberFormat>
<AssemblyRevisionType>AutoIncrement</AssemblyRevisionType>
<AssemblyRevisionFormat>00</AssemblyRevisionFormat>
</PropertyGroup>
<!-- Properties for controlling the Assembly File Version -->
<PropertyGroup>
<AssemblyFileMajorVersion>4</AssemblyFileMajorVersion>
<AssemblyFileMinorVersion>0</AssemblyFileMinorVersion>
<AssemblyFileBuildNumber></AssemblyFileBuildNumber>
<AssemblyFileRevision></AssemblyFileRevision>
<AssemblyFileBuildNumberType>DateString</AssemblyFileBuildNumberType>
<AssemblyFileBuildNumberFormat>01MMdd</AssemblyFileBuildNumberFormat>
<AssemblyFileRevisionType>AutoIncrement</AssemblyFileRevisionType>
<AssemblyFileRevisionFormat>00</AssemblyFileRevisionFormat>
</PropertyGroup>
Next I set the assemblyInfo.cs file's version to 1.0.0.0 in every project. Finally I saved and close it, reopened solution, and built. It works like a champ!
Now what want is to customize the Version to 4.0.1053.1 where 10 is the part of year indicator which is 2010 and 53 denotes the week number, at last 1 denotes revision number.
How to achieve this using the AssemblyInfo Task? I came across several posts that a new version of AssemblyInfo Task is available in Build Extension Pack.
I have installed the MSBuild Extension Pack December 2010 and its version is MSBuild Extension Pack 4.0.2.0 Installer

First.. use a globalassemblyinfo.cs that is linked from each project.
Add its as linked file to each project.
This means you update one file, not 30+ assemblyinfo files...then:
use MSBuild.Community.Tasks....
Then call
<AssemblyInfo CodeLanguage="CS"
OutputFile="$(VersionFile)"
AssemblyCompany="Company"
AssemblyProduct="Product"
AssemblyCopyright="Copyright © Company 2011"
ComVisible="false"
AssemblyVersion="$(BUILD_NUMBER)"
AssemblyFileVersion="$(BUILD_NUMBER)" />
Assuming you have something like:
<Import Project=".\tasks\MSBuild.Community.Tasks.Targets"/>

I do this in Jenkins by having a package build that is parameterised using the List Subversion Tags parameter type. The Subversion tag must follow the version number format (major.minor.revision.build), e.g. tags/2.0.0.1. The tag name is then assigned to a Jenkins parameter, e.g. $VERSION becomes 2.0.0.1
I use the WriteLinesToFile msbuild task to write out the assembly attribute to a second file alongside the PropertyInfo.cs called VersionInfo.cs. As checked in to source control, this just contains a default version number:
// Do not change this. The version is set on package builds only by setting the AsmVersion MSBuild property
[assembly: System.Reflection.AssemblyVersion("0.0.0.0")]
The package build on the build server passes in the version via the AsmVersion parameter:
/p:AsmVersion=$VERSION
The .csproj file is modified to have a BeforeBuild target (Visual Studio creates a commented out one for you):
<Target Name="BeforeBuild">
<WriteLinesToFile
Condition=" '$(AsmVersion)' != '' " File="Properties\VersionInfo.cs"
Overwrite="True"
Lines="[assembly: System.Reflection.AssemblyVersion("$(AsmVersion)")] // Generated by build" />
</Target>
When building in Visual Studio, or without passing in the AsmVersion, your assembly will have a default version of 0.0.0.0. When building in the package build, you will get your desired build number.

As #bruceboughton proposed, you can easily generate a version assembly file during compilation without using MSBuild.Community.Tasks library:
<PropertyGroup>
<Version>0.0.0</Version>
<InformationalVersion>0.0.0-dev~commithash</InformationalVersion>
<VersionFileName>$(BaseIntermediateOutputPath)Version.cs</VersionFileName>
</PropertyGroup>
<Target Name="GenerateVersionFile" BeforeTargets="BeforeBuild">
<WriteLinesToFile
File="$(VersionFileName)"
Overwrite="True"
Lines="
[assembly: System.Reflection.AssemblyVersion("$(Version)")]
[assembly: System.Reflection.AssemblyFileVersion("$(Version)")]
[assembly: System.Reflection.AssemblyInformationalVersion("$(InformationalVersion)")]" />
<ItemGroup>
<Compile Include="$(VersionFileName)" />
</ItemGroup>
</Target>
Remove definitions of the parameters you specify in the generated file from Properties\AssemblyInfo.cs file.
After that you can specify version by adding a parameter to the msbuild:
msbuild /property:Version=1.2.3 /property:InformationalVersion=1.2.3-dev~commithash .\SolutionFile.sln

Update for .NET Core style .csproj files: If you've come upon this question after having transitioned to the new .csproj format used by .NET Core, you can just set the Version property (no need to to bother with MSBuild tasks).

How I finally got this to work MSBuild version 12 (VS 2013).
Used Nuget to get MSBuildTasks Community package
Edited my .csproj file and added a path to the import the package:
<Import Project="..\packages\MSBuildTasks.1.5.0.235\build\MSBuildTasks.targets" Condition="Exists('..\packages\MSBuildTasks.1.5.0.235\build\MSBuildTasks.target')"/>
Figured out the Regex to change just the Revision number in the AssemblyInfo.cs file:
(?<=AssemblyFileVersion\("[0-9]\.[0-9]\.[0-9]\.)(\*)
which is not XML compatible, so has to be changed to:
(?<=AssemblyFileVersion\("[0-9]\.[0-9]\.[0-9]\.)(\*)
Uncommented the <Target Name="BeforeBuild"> section and added the following:
<Target Name="BeforeBuild">
<FileUpdate Files="properties\AssemblyInfo.cs"
Regex="(?<=AssemblyFileVersion\("[0-9]\.[0-9]\.[0-9]\.)(\*)"
ReplacementText="$(Revision)" />
</Target>
When running MSBuild added the "Revision" property to the command line e.g.
msbuild.exe myProject.csproj /t:Build /p:Configuration=Release;Revision=12345

MSBuild nuget RestoreOutputPath how to make it work?

New msbuild csproj format have got integrated nuget commands. It's possible to change default path where project assets will be restored by using <RestoreOutputPath>obj\profile7</RestoreOutputPath> command in project file.
But if I add <RestoreOutputPath>obj\profile7</RestoreOutputPath> to csproj file consequent commands
dotnet restore myproj.sln
dotnet build myproj.sln
produce build errors
obj\project.assets.json' not found. Run a NuGet package restore to generate this file.
How to tell MSBuild to get nuget assets from this obj\Profile7 path during the build command?
The restore output path needs to be the same as MSBuildProjectExtensionsPath so that the nuget generated props and targets files will be imported by the common props and targets. as well as BaseIntermediateOutputPath will be the default for composing the path to ProjectAssetsFile.
At least for the NuGet imports, it is important that MSBuildProjectExtensionsPath or BaseIntermediateOutputPath is set before the SDK props file is imported.
The simplest way to solve all of these issues is to set BaseIntermediateOutputPath very early in the project so that all components will take its value as a default base path - this is essentially redirecting obj to somewhere else.
This conflicts with the <Project SDK="..."> syntax since there is no way to set properties before the SDK's props file. To work around this, the project can be changed like this:
<Project>
<!-- This needs to be set before Sdk.props -->
<PropertyGroup>
<BaseIntermediateOutputPath>obj\SomeSubDir\</BaseIntermediateOutputPath>
</PropertyGroup>
<Import Project="Sdk.props" Sdk="Microsoft.NET.Sdk" />
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>
<!-- other content -->
<Import Project="Sdk.targets" Sdk="Microsoft.NET.Sdk" />
</Project>
An alternative would be to create a Directory.Build.props file that will be automatically imported early enough, but this would apply the value to all projects in the directory and take away the ability to specify the value per project.

MSBuild multiple dll in a single NuGet package

I have a Visual Studio 2017 solution that contains two projects:
Foo.csproj
Foo.Core.csproj
Both of these projects target multiple frameworks: net452;netstandard1.2
Foo.csproj includes a project reference to Foo.Core.csproj:
<ItemGroup>
<ProjectReference Include="..\Foo.Core\Foo.Core.csproj" />
</ItemGroup>
When I generate a NuGet package for Foo.csproj, I want the nupkg file to include both of these assemblies.
What is currently happening is that the NuGet package that gets created has Foo.dll and then a NuGet dependency on Foo.Core (which doesn't exist).
How can I generate a single NuGet package using msbuild that will include both assemblies?
For reference this is the command I am currently using (which is not working how I want it to):
msbuild /p:restore,pack Foo.csproj
This is currently not directly supported by NuGet out of the box. You can follow this GitHub issue for updates.
However, there are a few ways to create such NuGet package.
Use the "Nugetizer 3000"
This is an newly developed tool to build NuGet packages from projects and works by installing the NuGet.Build.Packaging nuget package. You can find some documentation on it on its GitHub wiki page but since it is a very new project, there isn't much documentation or community knowledge around it yet(!) (but the team developing it is very helpful, you could file GitHub issues if you get stuck).
Adding a custom target in the project (2.0.0 tooling / VS 2017 15.3+): Create an item in the csproj that will include the referenced project's output DLL
This approach is very hacky as it relies on an internal MSBuild item that the pack targets use. It works by first marking the <ProjectReference> to not be referenced from the created nuget package like this:
<ProjectReference Include="..\libA\libA.csproj" PrivateAssets="All"/>
Then you can add this to the project to include the generated libA.dll in the nuget package:
<PropertyGroup>
<TargetsForTfmSpecificBuildOutput>$(TargetsForTfmSpecificBuildOutput);IncludeP2PAssets</TargetsForTfmSpecificBuildOutput>
</PropertyGroup>
<Target Name="IncludeP2PAssets">
<ItemGroup>
<BuildOutputInPackage Include="$(OutputPath)\testprivatelib.dll" />
</ItemGroup>
</Target>
Note that this requires you to add all the <PackageReference> items of the referenced project to the project you generate the package from since they would be missing from the generated package since you effectively disabled the transitive reference behaviour.
Create a custom .nuspec file
At the time of writing, this is probably the most "supported" way, but also the most complex. NuGet allows you to disable the automatic generation of the resulting .nuspec file and automatic collection of files by setting the <NuspecFile> property in your project, along with a <NuspecProperties> property that allows you to pass replacement tokens for parsing the .nuspec file.
This works by modifying the project file like this:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netstandard1.4</TargetFramework>
<NuspecFile>$(MSBuildThisFileDirectory)$(MSBuildProjectName).nuspec</NuspecFile>
</PropertyGroup>
<ItemGroup>
<ProjectReference Include="..\LibB\LibB.csproj" />
</ItemGroup>
<Target Name="SetNuspecProperties" BeforeTargets="GenerateNuspec">
<PropertyGroup>
<NuspecProperties>$(NuspecProperties);id=$(AssemblyName)</NuspecProperties>
<NuspecProperties>$(NuspecProperties);config=$(Configuration)</NuspecProperties>
<NuspecProperties>$(NuspecProperties);version=$(PackageVersion)</NuspecProperties>
<NuspecProperties>$(NuspecProperties);description=$(Description)</NuspecProperties>
<NuspecProperties>$(NuspecProperties);authors=$(Authors)</NuspecProperties>
</PropertyGroup>
</Target>
</Project>
This will automatically look for a .nuspec file with the same name as the project (somelib.csproj => somelib.nuspec) and pass some properties along to it. The properties are created in a target in order to be able to access fully resolved and defaulted properties like PackageVersion.
The .nuspec file could look like this:
<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2012/06/nuspec.xsd">
<metadata>
<id>$id$</id>
<version>$version$</version>
<authors>$authors$</authors>
<requireLicenseAcceptance>false</requireLicenseAcceptance>
<description>$description$</description>
<dependencies>
<group targetFramework=".NETStandard1.4">
<dependency id="NETStandard.Library" version="1.6.1" exclude="Build,Analyzers" />
</group>
</dependencies>
</metadata>
<files>
<file src="bin\$config$\netstandard1.4\*.dll" target="lib\netstandard1.4\" />
</files>
</package>
Note that you must add all referenced NuGet packages as a <dependency> element in the .nuspec file since these are no longer automatically generated from the <PackageReference> items in your project file. Refer to the NuSpec Reference for more details.
I have recently created an example project on GitHub demonstrating the use of a custom .nuspec file for exactly this purpose.
The second option that Martin Ullrich mentioned is the only one that works out of the box with .NET Standard that allows to "Generate NuGet package on build" as an integral part of the build.
However like he mentions it has a "hard coded" dependency on a dll with an exact name that you expect to be there (on the output folder) which might bite you in the future. I've found a better alternative which worked for me in .NET Standard without the need of any other modification on this post.
I'll quote it here for completeness.
First you edit your csproj and define the PrivateAssets tag for the reference that you'd like to include:
<ItemGroup>
<ProjectReference Include="..\ClassLibrary1\ClassLibrary1.csproj">
<PrivateAssets>all</PrivateAssets>
</ProjectReference>
</ItemGroup>
Then you add this to your csproj:
<PropertyGroup>
<TargetsForTfmSpecificBuildOutput>$(TargetsForTfmSpecificBuildOutput);CopyProjectReferencesToPackage</TargetsForTfmSpecificBuildOutput>
</PropertyGroup>
<Target Name="CopyProjectReferencesToPackage" DependsOnTargets="ResolveReferences">
<ItemGroup>
<BuildOutputInPackage Include="#(ReferenceCopyLocalPaths->WithMetadataValue('ReferenceSourceTarget', 'ProjectReference')->WithMetadataValue('PrivateAssets', 'all'))" />
</ItemGroup>
</Target>
That post also shows how to include the PDBs in the NuGet package option if necessary (which I omitted here).
Been struggling with the same issue and none of the suggested workarounds worked (https://github.com/NuGet/Home/issues/3891) and I couldn't change the csproj to use the new SDK coming with .netcore.
Luckily the nuget pack command comes with the -IncludeReferencedProjects option (ref: https://learn.microsoft.com/en-us/nuget/tools/cli-ref-pack) which does exactly that:
"Indicates that the built package should include referenced projects either as dependencies or as part of the package. If a referenced project has a corresponding .nuspec file that has the same name as the project, then that referenced project is added as a dependency. Otherwise, the referenced project is added as part of the package."
Regardless of the *.nuspec file (not needed here) , add -IncludeReferencedProjects to the pack command and the referenced project dlls will be included along with the nuget dll.
nuget.exe pack yourProject.csproj -IncludeReferencedProjects
I have recently discovered that you CANNOT set defaults for the Nuspec Properties you want to replace in the msbuild command line e.g. if a metadata value is set in the .csproj file of "<Version>2.0.0</Version>" and you run:
msbuild myproject.csproj -t:pack -p:Configuration=Release -p:NuspecProperties=Configuration=Release;PackageVersion=1.2.3
Your .nupgk file will have the version 2.0.0 still. Annoyingly the MS documentation is not clear on this and no error is displayed.

MSBuild - Create a property with wildcards?

I'm currently moving my project to Visual Studio 2012 and start using nuget.
So I'll use the "NUnit Runners" nuget package instead of a nunit library.
The problem being that nuget creates folders with the package version. For example, NUnit Runners is inside the folder:
src\packages\NUnit.Runners.2.6.1\
Until now, Nunit was inside my lib\NUnit folder.
So, inside my MSBuild file, I was executing the tests by specifying the path:
<PropertyGroup>
<NUnitFolder>$(MSBuildProjectDirectory)\lib\NUnit</NUnitFolder>
</PropertyGroup>
<NUnit Assemblies="..." ToolPath="$(NUnitFolder)" />
But I don't want to have to specify a version number inside my msbuild task, that I would have to update everytime NUnit.Runners is updated.
I tried to play around with CreateProperty, but it doesn't seem to accept wildcards.
I also tried ItemGroup, but it works for a list of files, not a folder.
In the end, instead of trying to create a property with a wildcard, in my case I retrieved the version of NUnit.Runners from the packages.config file.
I now have a Target like this:
<Target Name="GetNUnitFolder">
<!-- Retrieves the version of NUnit.Runners from the solution's packages.config file -->
<XmlRead Namespace=""
XPath="packages/package[#id='NUnit.Runners']/#version"
XmlFileName="$(MSBuildProjectDirectory)\src\.nuget\packages.config">
<Output TaskParameter="Value" PropertyName="NUnitVersion" />
</XmlRead>
<CreateProperty Value="$(MSBuildProjectDirectory)\src\packages\NUnit.Runners.$(NUnitVersion)\tools">
<Output TaskParameter="Value" PropertyName="NUnitFolder" />
</CreateProperty>
</Target>
Note: to be able to use XmlRead, you need the MSBuildCommunityTasks.
And once I have the version, I rebuild my NUnitFolder property.

MSBUILD web deploy package does not include the project reference DLL's

When I try to create a package for web deploy using msbuild it only includes the projects dll. The package zip file or the temp directory does not include the referenced project's dlls.
I've looked at this post and that is not my problem. I am definitely using the code from the referenced projects in my main project that I'm creating the deployment package for.
I'm using MSBUILD 4 to create the package.
When I create the package using VS2010 using the exact same project file it works fine. All the referenced projects have their dlls included in the package.zip file.
I've tried changing the location of the _PackageTempDir and that did not solve the problem either.
I've tried taking out the ExcludeFilesFromDeployment property and set the PackageAsSingleFile setting to false to see if that would change the results.
Here is my target for Package. All the regex is so I can pull my project file name off the end of a search path and then use that name for the name of the output folder and the name of the zip file. The PackageOutputDir is a propertyI am importing.
<Target Name="Package">
<MSBuild Projects="#(PackageProject)" Targets="Package" Properties="Platform=$(Platform);
Configuration=$(Configuration);
DeployOnBuild=true;
DeployTarget=Package;
PackageLocation=$(PackageOutputDir)\$([System.Text.RegularExpressions.Regex]::Split($(ProjectName), '(.*\\)([a-z,A-Z,0-9,_,-]+)(\.\*proj;)')[2])\$([System.Text.RegularExpressions.Regex]::Split($(ProjectName), '(.*\\)([a-z,A-Z,0-9,_,-]+)(\.\*proj;)')[2]).zip;
PackageAsSingleFile=true;
ExcludeFilesFromDeployment=Web.config;
_PackageTempDir=$(PackageOutputDir)\temp;">
</MSBuild>
</Target>
Any ideas as to why it is not including my referenced project dlls?
You could do the following in your MasterBuild.proj.
<Target Name="Package">
<ConvertToAbsolutePath Paths="$(PackageOutputDir)">
<Output TaskParameter="AbsolutePaths" PropertyName="Source_Dir_Abs"/>
</ConvertToAbsolutePath>
<MSBuild Projects="#(PackageProject)" Targets="Package"
properties="Platform=$(Platform);
Configuration=$(Configuration);
DeployOnBuild=false;
DeployTarget=Package;
PackageLocation=$(Source_Dir_Abs)\$(PackageProjectName).zip;
PackageAsSingleFile=true;
ExcludeFilesFromDeployment=Web.config;
_PackageTempDir=$(PackageOutputDir)\temp;">
</MSBuild>
</Target>
Where you are calling msbuild you will need to add a property that will be used in $(PackageProjectName) by doing the following:
msbuild.exe /property:PackageProjectName=$project

Specifying assembly version of all projects within a web deployment wdproj script

I have a .wdproj Web Deployment Project created with VS2010 that contains references to other class libraries, like this:
<Project ToolsVersion="4.0" DefaultTargets="Build"
xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ProjectReference Include="..\Path\Proj1.csproj">
<Project>{GUID-HERE}</Project>
<Name>Proj1</Name>
</ProjectReference>
<ProjectReference Include="..\Path\Proj2.csproj">
<Project>{GUID-HERE}</Project>
<Name>Proj2</Name>
</ProjectReference>
There are lots of these. I want to be able to run msbuild /t:Rebuild /p:Configuration=Release and have all the assemblies of all the included projects compiled at a specified version. Nothing fancy just static like 2.5.6.0 and specified once in the wdproj file. I dont want to open 30 files manually.
I have looked at MSBuild Community Task and MSBuildExtension Pack and can not get anything to work. The build runs ok without errors.
Anyone have an example of how this can be done?
This is an attempt with MSBuild Extensions (adapted from the sample included) that doesn't work:
<Import Project="$(MSBuildExtensionsPath)\ExtensionPack\4.0\MSBuild.ExtensionPack.VersionNumber.targets"/>
<Target Name="Build">
<MSBuild.ExtensionPack.Framework.AssemblyInfo
ComVisible="true"
AssemblyInfoFiles="VersionInfo.cs"
AssemblyFileMajorVersion="2"
AssemblyFileMinorVersion="5"
AssemblyFileBuildNumber="6"
AssemblyFileRevision="0"
/>
</Target>
MSBuild is definately looking at the MSBuild.ExtensionPack.Framework.AssemblyInfo element because if the attribute names are incorrect the build will fail. This builds ok but none of the versions on the referenced assemblies are changed. The version numbers on the ASP.NET page assemblies from the website are all 0.0.0.0.
Are you maybe missing to specify the CodeLanguage and OutputFile attributes?
I think the AssemblyInfo task is intended to generate (replace) a source file prior to compiling.
