I have the following warning when building some of my class library csprojs:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(2110,5): warning MSB3101: Could not write state file "..\..\tmp\dotnet\anvil.controls\obj\vs2017\net461\debug
\anvil.controls.vs2017.net461.csprojAssemblyReference.cache". The file 'E:\anvil\Anvil.Controls\tmp\dotnet\anvil.controls\obj\vs2017\net461\debug\Anvil.Controls.vs2017.net461.csprojAssemblyReference.cache' already exists. [E:\anvil\Anvil.Controls\src\anvil.controls\anvil.controls.vs2017.net461.csproj]
I've tried using msbuild 15.0 (VS2017 and Standalone 2.2.103) and 16.0.
Same warning in Visual Studio 2017 and JetBrains.Rider
Does not happen if I wipe my temp folder. Then happens in subsequent builds or even rebuilds.
Happens to a subset of my projects, only similarity I can see is that they are all projects that contain .xaml files. But it doesn't happen on all projects with .xaml files.
Happens when I use -maxcpucount:1 (to disable parallel build).
Each project has a unique tmp/intermediate folder, set to this: ..\..\tmp\dotnet\ubisoft.controls\<bin|obj>\vs2017\net45\<debug|release>\
Any ideas what might affect this error in my projects?
Sometimes 'mysterious warnings' (and errors) come from too long paths. Try to use a shorter output path, i.e.
E:\build\Anvil.Controls\tmp\net461\debug\
instead of
E:\anvil\Anvil.Controls\tmp\dotnet\anvil.controls\obj\vs2017\net461\debug\

I have configured a TFS(2017) build pipeline to compile a VS extension with debug mode for a specific requirement which require .pdb files.
The build solution task fails for "debug" configuration with below error, however same pipeline works for the release configuration.
I have tried the approach mentioned in the following discussion as well, howewer it doesn't resolve my issue.
https://social.msdn.microsoft.com/Forums/vstudio/en-US/fd220999-5761-475a-bf86-98dff6b35218/unable-to-compile-vsix-project-that-is-a-part-of-my-solution-using-amd64-msbuild-from-vs2015?forum=msbuild
Appreciate if someone can help me to resolve this issue.
Following is the build configuration used for the Build Solution task:
Following build variables are used to configure build parameters.
Build Error message:
packages\Microsoft.VSSDK.BuildTools.15.1.192\tools\VSSDK\Microsoft.VsSDK.targets
(633, 5)
packages\Microsoft.VSSDK.BuildTools.15.1.192\tools\VSSDK\Microsoft.VsSDK.targets(633,5):
Error VSSDK1077: Unable to locate the extensions directory. "Value

Update your Microsoft.VSSDK.BuildTools NuGet package to latest version 15.9.3032, just in case it is a problem already solved.
Release configurations can also generate PDB files (Project properties, Build tab, Advanced...button, Output > Debugging information). So, if the Release configuration works for you, you can keep using it while also generating a pdb file with full debug information.
The error is happening when, once compiled correctly, the generated VSIX output file is going to be deployed to the folder for extensions of the experimental VS instance, which is a required step to debug the VSIX file. A possible explanation of the different behavior for Debug/Release configurations is that maybe your .csproj specifies <DeployExtension>False</DeployExtension> for the Release configuration. By default, if not set, that property is set to true in the Microsoft.VsSDK.targets file:
<DeployExtension Condition="'$(DeployExtension)' == ''">true</DeployExtension>
Since likely you don't need to deploy the VSIX to the VS experimental instance when building on a build server (because you are not going to debug it), you can set that property to False to skip the deployment. This can be done with a 3rd build configuration (ex: "DebugBuildServer"), for which you specify DeployExtension to False in the .csproj file, or sticking to two build configurations but passing the /p:DeployExtension=false in the MSBuild arguments of the Visual Studio Build task of your build pipeline.
When I run my TeamCity build with the only build step being of runner type Visual Studio (sln), I get the following error:
C:\TeamCity\buildAgent\work\4978ec6ee0ade5b4\Test\Code\Test.sln(2, 1): error MSB4025: The project file could not be loaded. Data at the root level is invalid. Line 2, position 1.
This is on a dedicated CI server running TeamCity Professional 8.1.1 (build 29939). There are several other successfully-running builds on this server.
The odd bit is that the same build runs successfully on TeamCity on my dev machine. I followed an answer to a similar question, and copied the specified folders across, but that didn't help.
I'm sure the project/solution file isn't invalid because in addition to the build running on my dev box, I have opened the solution in Visual Studio and built it there with no problems.
Any suggestions?
I just fixed this.
Look inside the Test.sln file for Project or EndProject tags that aren't closed. For us, the EndProject was missing and it broke on teamcity, but no issues in Visual Studio.
It seems the TeamCity error message will occur for any number of root causes. In my case the problem occurred because a line inside the GlobalSection(NestedProjects) section was referring to a project Guid which didn't relate to any project defined in the Solution file.
As with the previous post I didn't have any issues building in Visual Studio. I only got a more helpful error message that allowed me to discover what the real problem was when I built using msbuild.
See https://therightjoin.wordpress.com/2014/07/04/msb4025-the-project-file-could-not-be-loaded-data-at-the-root-level-is-invalid-error-when-building-ssdt-project-in-teamcity for another example, and where using msbuild helped identify the true problem.
In our case, it was a duplicate project reference in the solution file (caused by near simultaneous commits and an automatic merge).
In our situation the problem was specifying a ToolsVersion that was not installed on that machine. (14 which VS2015 has but VS2017 does not have by default)
In my case, after merging, in .sln file, it was a mismatch of lines under
GlobalSection(NestedProjects) = preSolution
{6B971E15-6B61-4AA8-9B93-9639C23269C3} = {9A14E7EF-3FA1-4B9A-B413-C550B3E5AC62}
{54D14F01-D576-4DE6-9404-D21AD0DC4916} = {9A14E7EF-3FA1-4B9A-B413-C550B3E5AC62}
... (was some extra entry here )
...
EndGlobalSection
section. In clear words, there were some extra lines added after merging. So, If you have merged, please compare two solution files manually. You can start with total line numbers in both files.
In another Case
We had a blank lines - so make sure any blank lines are removed!
Hope this helps some else too!
I got this same error with Jenkins. It turns out the root Jenkins folder was set to C:\Program Files (x86)\ and it didn't have write access to bin and obj directories.
Error:
error MSB4025: The project file could not be loaded. Data at the root level is invalid.
I launched cmd as Administrator and ran this:
"C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" "C:\Program Files (x86)\Jenkins\workspace\BuildBI_1\Reports\Test\ReportsTests.sln" /t:Build /p:RunOctoPack=true
And that gave me clues about not being able to write to bin and obj.
This worked for me-
You can install Build Tools for Visual Studio 2017, make sure to select C++ tools, Windows 10 SDK and MSBuild and your set.
Use MSBuild to identify the underlying problem:
$> msbuild mysolution.sln
Gave me this beauty with the correct error line number:
If msbuild cannot be accessed like that from the command line / powershell, try to find the MSBuild.exe shipped with VisualStudio, e.g. C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\amd64\MSBuild.exe.
VisualStudio itself seems to be very "tolerant" against errors / inconsistencies in the solution file, so having it open in VS is no guarantee for the sln file being correct.
I fixed it by updating the solution file.
Another possible problem (and resolution): I had a stray unused solution file in my repo, pointing to who-knows-where, and the MSBUILD step in my Azure DevOps pipeline was set to **\*.sln.
Building my Jenkins/MSBuild solution gives me this error
c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(483,9): error :
The OutputPath property is not set for project '<projectname>.csproj'. Please check to
make sure that you have specified a valid combination of Configuration and Platform
for this project. Configuration='Latest' Platform='AnyCPU'. You may be seeing this
message because you are trying to build a project without a solution file, and have
specified a non-default Configuration or Platform that doesn't exist for this project.
[C:\<path>\<projectname>.csproj]
Any ideas?
EDIT
I have this in my .csproj file
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Latest|AnyCPU'">
<OutputPath>bin\Latest\</OutputPath>
</PropertyGroup>
I have figured out how it works (without changing sln/csproj properties in VS2013/2015).
if you want to build .sln file:
/p:ConfigurationPlatforms=Release /p:Platform="Any CPU"
if you want to build .csproj file:
/p:Configuration=Release /p:Platform=AnyCPU
notice the "Any CPU" vs AnyCPU
check the code analysis, fxcop, test coverage(NCover) targets, as well as the MSBUILD should be located properly. In my case its:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319
but it can be different as you can see microsoft has given 6 cmd options to build code base::AMD (with cross plt, x86 & x64 options) and Windows(cross, x86, x64) and that also when code development happened with default JIT (it can be PreJIT ngen.exe, econoJIT)
I think more than this troubleshooting can be handle using power shell + msbuild. May be helpful for someone ...
Open up your csproj in a text editor and see if you have a property group section, should look something like this:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Latest|AnyCPU' ">
<DebugSymbols>true</DebugSymbols>
<DebugType>full</DebugType>
<Optimize>false</Optimize>
<OutputPath>bin\Latest\</OutputPath>
<DefineConstants>DEBUG;TRACE</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
<TreatWarningsAsErrors>true</TreatWarningsAsErrors>
</PropertyGroup>
Do you have a 'Latest' build configuration? If not add the above section to the csproj.
As mentioned by perlyking, rather than editing the csproj XML The following worked for me. Here are the steps I used.
Open the Project Properties.
Select the Build Tab.
Under the Output section, Check that an output path is set. (if not set one, save the project and it should work).
If it is set, click on the "Browse..." button of the output path.
When the folder selection dialog opens, Navigate up one level in the
file browser and then re-select the output folder and click
the "Select Folder" button.
Save the project properties and it should work.
To add to what #James said, I found that if I looked at the project Compile properties in VS2013, the Build Output Path was specified. But when I examined the .csproj file directly, the OutputPath element was missing for the relevant build configuration. So in VS I simply made and reversed a minor edit to the output path, saved it, and that kicked the value into the project file, and I was then able to build.
I was using MSBuild to build multiple .sln files, and had added a new step to build a .csproj file as well, when I encountered this error.
#Saurabh's answer highlighted the root of the problem. However, when fixing it, adding /p:Platform=AnyCPU to the MSBuild Arguments section didn't fix it. I actually needed to update the Platform value on the build step.
All other build steps were using the $(BuildPlatform) variable value (which happened to be "any cpu", with a space in it).
(Had I been building multiple .csproj files, I probably would have created a second variable for the AnyCPU platform.)
For me the answer was to fix all the projects in Build > Configuration Manager.
If you have some projects where the name or platform does not match the solution configuration, you should change it so they all match.
I was running into this issue while updating an older project with additional project configurations for per-environment config transforms.
It turns out that when the project configurations were added to the csproj file, they were inserted after an Import element which caused the issue.
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'ProjectName.Dev|AnyCPU'">
...
Moving the Import element after all the PropertyGroup definitions fixed the problem for me.
Relevant similar case: https://stackoverflow.com/a/31072208/2452820
I got this error only when I was publishing my web project. I had mistakenly selected the wrong build configuration when setting up the publish profile.
I had same issue. I have updated my windows platform by using command line. Currently i got updated to windows#5.0.0 version. Then you need to search for file name "SQLite3.UWP.vcxproj". Try to change "v141" to "v140". Currently I am using Visual Studio 2015 professional. If it's Visual Studio 2017, then there is no need to change version in SQLite3.UWP.vcxproj file.
In my case this error happened because the output folder included a dot to make it relative to the current directory. The problem was solved by removing the dot.
The offending Build output path was:
.\bin\Output
The problem was solved by changing it to
bin\Output
The build output path can be found in the Build tab of the project properties, and there is a different path for each combination of Configuration and Platform.
Just had the issue for some service fabric stuff in MSBuild.
First step was right clicking each affected project and pulling up their Properties, selecting the Build tab, then setting the platform target to x64.
Second step was to go into the configuration manager and set each project to also use x64 for Debug and Release.
This was for a VS2017 project.
I had the same problem on a few projects. After adding a new configuration to the projects, the PropertyGroup was added at the very end of the Project file.
Moving the PropertyGroup to right after all the other configurations PropertyGroup fixed the issue.
I hope this helps.
I had this witha slightly unusual SLN/CSPROJ file arrangement:
I had project files:
A.csproj, with configurations "Dev" and "Production"
B.csproj, with configurations "Dev" and "Production"
C.csproj, a "common" library used by both A and B with configurations "Dev" and "Production"
And I had SLN files:
AC.sln, with configuration "Production" - this is used by jenkins to build project A and the common library
BC.sln, with configuration "Production" - this is used by jenkins to build project B and the common library
ABC.sln, with configuration "Dev" - this is used by developers in VS to write new code without having to keep opening different solutions (this answer is a simplified view of a 55-project solution)
I'd made an edit to the common library and introduced a dependency on project A. AC.sln would still build in jenkins but BC.sln gave an error saying:
The OutputPath property is not set for project 'A.csproj'. Please check to
make sure that you have specified a valid combination of Configuration and Platform
for this project. Configuration='Debug' Platform='AnyCPU'.
It was initially puzzling because we don't even have a Debug config anywhere in any project; find in files for Debug| turned up 0 hits
ABC.sln that the human developers use in VS would also build fine. Building BC.sln gave an error that A.dll wasn't found
When the circular irresolvable problem of C depending on A was removed, everything started working again
This error is misleading and can be caused by a different issue. Check the entire message:
The OutputPath property is not set for project 'myproject'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='myconfig' Platform='AnyCPU'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform.
My build configuration was missing this node in the csproj:
<PlatformTarget>AnyCPU</PlatformTarget>
Despite saying AnyCPU was the selected Platform in the dropdown, the actual xml was not there. Adding it fixed the mismatch between the project and the other project it was referencing.
The OutputPath property is not set for project error message will appear if a Platform environment variable exists (as seems to happen on HP laptops) and the target of MSBuild contains a reference to another Visual Studio project.
After renaming the Platform environment variable my build now works.
It seems the parameter /p:Platform="Any CPU" gets applied to the target solution but doesn't 'carryover' to referenced projects. In my instance, the error message indicated referenced projects were using the environment variable Platform=MCD.
I had two project configs, Debug and Release. When the Release build was used, it was throwing this error. The issue I found was that in the csproj file, the Debug config was near the top and the Release config was all the way at the bottom.
Manually moving the Release build just below the Debug build fixed it.
I'm assuming I did something incorrectly when setting up my build configurations because this doesn't feel like something I should have had to manually adjust.
Edit the properties of the project:
Make sure "Configuration Properties->General->Output Directory" is not blank. Note, it's not called OutputPath here. You can probably copy the value from Intermediate Directory.
I encountered the same problems when build TheXTech (https://github.com/Wohlstand/TheXTech/wiki/Building-on-Windows#building-in-visual-studio-201520172019-and-cmake) recently. And finally I found it is a cmake -A issue. The correct arch for 64 bit on windows is x64, not Win64.
For some more reference, see https://cmake.org/cmake/help/v3.16/generator/Visual%20Studio%2016%202019.html#platform-selection, https://cmake.org/pipermail/cmake/2019-April/069379.html.
Go to Solution properties and change the configuration to Any CPU or X64 or X86, and if build is checked uncheck that for what you are getting error for. By default, project build that for build configuration in solution and throw error as mentioned when building the project.
My MSBuild build script executes fine on all the development machines, but fails to run on the build server, except for the Trunk build. Branches all fail with the following warnings indicating the source of the problem:
Target "ResolveProjectReferences":
C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets (0,0):
warning : The referenced project '..\..\..\Class Library\
Company.BusinessModel\Company.BusinessModel.csproj' does not exist.
I can't understand why this error is even appearing - I have verified that (relative to the csproj being processed) the referenced project does exist. Copying (file copy) the checked out code to my local machine and running the script, the build completes as expected.
Is there anything obviously wrong here? Anything I can check to try and resolve this mystery?
EDIT:
I've tried running MSBuild against the project raising the build error in isolation, so it's not the rest of the solution which is the problem, just something about this specific .csproj file.
I actually found the problem. It's a bug in Visual Studio 2010 with path names totalling 259
http://support.microsoft.com/kb/2516078
Have you run msbuild in diag mode. That should give you some hints about the current path, and the relative path that MSBuild is trying to search.
msbuild myproj.msbuild /v:diag
