Hi GoodTekken,

Welcome to MSDN forum.

According to your description, I suggest you could go to your project path and check if this NuGet package: Microsoft.CodeAnalysis.FxCopAnalyzers v… exists.

If this NuGet package exists, please remove this NuGet package and check if this issue persists.

If not, then go to this path: C:\Users\user name]\nuget\packages and check if this NuGet package exists and remove it if you could find it.

If this issue still persists, according to this thread: Csc.exe exited with code -1073741819 (it’s an old thread but maybe helpful and you could refer to it) do you have more than one instance of VS running on your computer? If yes, try to stop it. Also check for other apps or services on your computer that may be accessing the files in your project (such as antivirus software).

You could try to reboot your computer and maybe try to start VS in Safe Mode via Developer Command Prompt for VS 2017 -> enter devenv /safemode and check if this issue persists.

Hope all above could help you.

Best Regards,

Tianyu

I have tried to reinstall Visual Studio Community 2017, and still shows the same errors.

How could I do for this exception?

And upgrade .net Framework to 4.8.0. but shows the same errors. Even just build("Hello World" ).

I can't move forward.

It happened by the antivirus software. Thank you very much.
