In my case, the issue was because I have a not valid fsproj. Look if your csproj is correct. Check your diff if you are using a source manager like git. Then, you can pass it through an xml validator then check it line by line with the doc. Good luck.

I have some libraries built on C# .NET Core 3.1.
When I execute the command
dotnet build "core\core.csproj"
I get the following error
C:\Users\christos.nuget\packages\visual-stylecop.msbuild\4.7.59\build\Visual-StyleCop.MSBuild.Targets(107,5): error MSB4062: The "StyleCopTask" task could not be loaded from the
assembly
C:\Users\christos.nuget\packages\visual-stylecop.msbuild\4.7.59\build..\tools\StyleCop.dll.
Could not load file or assembly 'System.Windows.Forms,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
The system cannot find the file specified. Confirm that the
declaration is correct, that the assembly and all its
dependencies are available, and that the task contains a public class
that implements Microsoft.Build.Framework.ITask.
But when I use msbuild
& 'C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\MSBuild.exe' "core\core.csproj"
it finishes without problems.
Any idea why?
thanks in advance for any help
When I type "dotnet build" the following error occurs:

I tried to add the package using:
dotnet add package Microsoft.CodeAnalysis --version 3.11.0
but it gives me this error:
error: nodename nor servname provided, or not known
Any idea how to fix this?
Solved the issue by changing microsoft.extensions.logging.abstractions version to v3.1.9 since I am using .net core version 3.1
I installed a XYZ package in my project of type class library. That new package depends on the file Microsoft.AspNetCore.Http.Abstractions.
When I do the deployment in OpenShift I have the following error:
"Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly >'Microsoft.AspNetCore.Http.Abstractions, version=3.1.0.0, Culture=neutral, >PublicKeyToken=xyzxyzxyz'. The system cannot find the file specified."
Has anyone seen this problem?
Thanks!
I am running a UWP app for windows iot core. I dropped in some code from a .net framework. I have converted most of the errors that occurred (most was compatible with the new update build 16299). I am now getting the error
System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Runtime.WindowsRuntime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.'
I keep seeing in some of the nuget packages i have installed:
Microsoft.NETCore.UniversalWindowsPlatform v6.0.6 that
System.Runtime.WindowsRuntime (>= 4.0.11) is covered.
I am not sure why it is looking for v 4.0.0.0.
Saw this thread but its slightly different: UWP application: Could not load file or assembly 'System.Runtime.WindowsRuntime, Version=4.0.14.0
Does anyone have any ideas?
I installed the 4.5.2 framework onto my R2 dev server last week, and have been getting this error, ever since. The files contain no reference to VisualStudio.Shell. Any ideas?

So I spent about 2 days trying to figure out what the heck was going...
The way I was able to fix it is by adding Microsoft.VisualStudio.Shell to
C:\Windows\assembly
But the only way to do that is using gacutil.
gacutil -i Microsoft.VisualStudio.Shell.dll
That fixed it for me. Hopefully it helps someone with the same problem.
