I have an ASP.NET Core 2.0 project developed using VS2017. I am getting the following error from our build server which uses TFS2015.
The default XML namespace of the project must be the MSBuild XML namespace. If the project is authored in the MSBuild 2003 format, please add xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to the element. If the project has been authored in the old 1.0 or 1.2 format, please convert it to MSBuild 2003 format.
I got this error when I initially setup the build, but after reading through various posts I resolved the issue by installing the VS2017 SDK and build tools on the build server. All well and good.
I have now added a unit testing project and getting the error again. I am also getting this warning.
Warning MSB4078 The project file is not supported by MSBuild and cannot be built
I get this error when the build attempts to build the solution file. I have installed the latest version of MSBUILD on the build server. What else do I need to do?

Project must provide a value for configuration. Msbuild failed wih this error and its working fine if doing build via vs 2017. But breaking when using Msbuild cmdline
Try deleting Microsoft.AspNetCore.Razor.Design in your .csproj file. That worked perfectly for me. I had the same issue, when I migrated my project from .NET Core 2.2 to .NET Core 3.0.
Trying to build a ASP.Net Core 1.0 project (.xproj) on a Build machine. Project built in VS2015. .Net Core is installed on the Build machine. I get this build error
The imported project "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Props" was not found. Confirmed that path in the declaration is correct, and file exists on disk.
Tried the suggestion from this stackoverflow questionbut doesn't help.
I can confirm that the path and file do exist on the build server.
Also tried passing MS Build Argument /p:VisualStudioVersion=14.
Any leads highly appreciated.
Project Setup : Mixed framework solution
.Net Framework 4.6.2 projects in solution : 15
.Net Standard 2.0 projects in solution - 1
Development Machine
Visual Studio 2017(15.7.4) : Builds without any errors
Build Server
TeamCity Version 2017.1.3
Build Steps
Nuget Restore(3.4.4)
dotnet Restore
MSBuild( Build Tools 2017), Tools Version 15.0
Build fails with following error in the .net standard 2.0 project : [ResolvePackageAssets] C:\Program Files\dotnet\sdk\2.1.301\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(198, 5): Package System.Security.Cryptography.ProtectedData, version 4.4.0 was not found. It might have been deleted since NuGet restore. Otherwise, NuGet restore might have only partially completed, which might have been due to maximum path length restrictions.
What's interesting is I can't find reference or use of System.Security.Cryptography.ProtectedData anywhere in the project. Any help is greatly appreciated.
P.S - Can't use dotnet build, as the solution needs building of licenses.licx files, and the component which builds it (Microsoft.Build.Tasks.LC) is not ported to .Net Core. The suggestion from various posts was to use MsBuild.exe
Our .net core 2.1 solution compiles fine on our local development machines with .net core sdk 2.1.301. Appveyor used to compile the solution in its CI pipeline when there was no database projects defined. Once such a project added, Appveyor started failing in building the solution with the error message below. Any clues how to address this issue?
C:\projects\comingsoon\ComsingSoonDatabase\ComsingSoonDatabase.sqlproj(57,3):
error MSB4019: The imported project "C:\Program
Files\dotnet\sdk\2.1.300\Microsoft\VisualStudio\v11.0\SSDT\Microsoft.Data.Tools.Schema.SqlTasks.targets"
was not found. Confirm that the path in the declaration is
correct, and that the file exists on disk.
The database project can only be built using the full framework MSBuild tools included in visual studio.
Depending on how you set up appveyor, you need to change your definition to use msbuild.exe instead of dotnet commands.
I'm getting the runtime error:
InvalidOperationException: Can not find assembly file mscorlib.dll at '...\bin\Debug\net462\refs,...\bin\Debug\net462\'
This had not been a problem until I updated to version 15.3.1 this morning, and installed the .Net Core 2.0 SDK.
The DLL's are present in my ~\.nuget\packages folder. I'd had the same issue with the "Microsoft.Csharp.dll" assembly until I copied and pasted it into the stated folder.
I tried specifying to use .Net Core 1.1.0 via a global.json file, but then I get the build error:
The version of Microsoft.NET.Sdk used by this project is insufficient to support references to libraries targeting .NET Standard 1.5 or higher. Please install version 2.0 or higher of the .NET Core SDK.
This error goes away if I clean the solution then restore Nuget packages via Command Line- not via the GUI. However it comes back if I change the version of a nuget package.
OK, this seem slightly different to my issue here: Visual Studio update 2017 15.3.1 forces ASP.NET Core SDK 2.0, which then doesn't find "reference assemblies"
If you install the SDK 2.0 from https://www.microsoft.com/net/download/core
You will then "probably" be able to build and run the project again but you'll be back to having the missing Microsoft.CSharp.dll / mscorelib.dll error.
If you then make sure the dependency is correct for the netstandard version:
<DependsOnNETStandard>netstandard1.5</DependsOnNETStandard>
See here: https://learn.microsoft.com/en-us/dotnet/standard/net-standard for the right version for you. My project is using core 1.1 targeting the full framework 4.6.1 and targeting netstandard1.6 has worked for me.
The final piece of the puzzel, was found on the GitHub issues here: https://github.com/dotnet/sdk/issues/1488
Add the following to your references in the .csproj file:
<PackageReference Include="Microsoft.Extensions.DependencyModel" Version="2.0.0" />
This will then build the project as a 1.1 project, but using the 2.0 SDK (which from what I can tell, it's supposed to do!). I can now run the project, update packages and generally got on with my work!
