Every time i try to build a code and debug it keeps popping this error on the command-line and later will output build 0 - successful 1 - skipped
then microsoft visual studio will prompt error in build, run previous version?

If you're encountering this problem (@megactek @itrice), can you please download and run https://github.com/microsoft/msbuild/blob/2d82e1a861d890fce68c8e2d42b569e5bbaf5687/scripts/EnumerateMSBuild.ps1 and share the results? You might have a Visual Studio installation problem, or you might have MSBuild assemblies in your Global Assembly Cache (GAC). If it's the latter, the instructions from this feedback issue might help you.

Hello I have the same problem.

Exception has been thrown by the target of an invocation. The project file could not be loaded. Could not load file or assembly 'Microsoft.Build.Framework, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

The error occurs when I execute the nuget restore command. Nuget version 4.6.2. I have two ways to solve this problem.

1. Use Nuget 4.8.2 and higher.
2. gacutil /i "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\Microsoft.Build.Framework.dll

But I need a different solution. If the version of msbuild is lower than 16.5 - everything is correct.

Enumerate MSBuild result attached.
msbuild_versions.txt

@rainersigwald here is the result of the run:
msbuild_versions.txt

[rainersigwald]

The error occurs when I execute the nuget restore command. Nuget version 4.6.2.

@megactek This should be resolved by #5257 in Visual Studio 2019 16.5.5.

@newCoderNovice can you describe what you're doing when this happens?
