Getting a csc.exe error with the .NET samples from the site. Running in a Windows 10 x64 environment; projects came in as Win 8 and were required to be retargeted to 8.1. Now the projects don't build. Turned on diagnostics logging to get the detail. Is there a way to get the full command line that is being invoked on build?

Description "csc.exe" exited with code -532462766. Project File C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.CSharp.CurrentVersion.targets Line 246

this is a generic CLR exception code 0xE0434352. capture a crash dump of csc.exe (procdump -ma -i C:\dumps) and analyze it with windbg (at end of this link: ig2600.blogspot.de/2009/07/…) – magicandre1981

I have the exact same error with a similar setup. Were you able to solve this issue? There is very little info about it online. – Xavier Peña
In my case it might look like it is a compiler error that is not recognized by Visual Studio. Other projects work just fine, but after applying a big refactoring to the project I'm working on this error suddenly happened and it won't go away. – Xavier Peña
Nevermind, I have solved it by re-doing the refactoring from scratch. This time it works perfectly. – Xavier Peña

Install-Package Microsoft.Net.Compilers -Version 1.2.1

This error can be generated by NuGet packages when some .dll are not available.

Delete packages folder and compile. It should restore all the NuGet packages.

I couldn't find out the reason of this, but a rollback of project settings to default solved the case for me. I guess Visual Studio 2015 somehow mixed up it's settings.

Go to tools -> options -> projects and solutions -> build and run

and change both MSBuild project build output verbosity and MSBuild project build log file verbosity verbosity levels to Normal, build your project again and watch the output window, if nothing new shows up change verbosity level to a higher one.

so easy, you just have to delete folder "bin" in your project and restart visual studio

This was happening to me yesterday.

Not sure if it was related, but this problem started for me soon after a /bin and /obj folder delete to cure another build issue.

I tried every suggestion on here and elsewhere, but in the end the only thing that worked was closing all my code files that were open in the IDE. Seems bonkers to me that this is really the cure, but if it saves someone 6 hours of their life then it's worth a shot.

If you are getting this error:

Try to execute the command on nuget packgae console:

Install-Package NuGetEnablePackageRestore
