发布：找不到路径的一部分……\\obj\\DEV\\AspnetCompileMerge\\Source\\bin\\roslyn\\csc.exe'

Question

I recently added the new .NET compiler NuGet packages (Microsoft.CodeDom.Providers.DotNetCompilerPlatfor) to an existing older MVC.NET website. Now when trying to publish the website I get the following exception:

Could not find a part of the path … \\obj\\DEV\\AspnetCompileMerge\\Source\\bin\\roslyn\\csc.exe'

I have tried everything mentioned in this question , but nothing worked. It is, after all, a slightly different problem. The problem mentioned in that post is build exceptions, my solution builds fine locally. Uninstalling the NuGet packages works, but that's not really a solution.

The issue is basically the same as this one, but that also has no solution.

Publish output:

4>------ Publish started: Project: Jdn.ArticleCatalogue.Web, Configuration: DEV Any CPU ------

Any ideas on how to solve this one?

Answer 1

This was a known issue whereby the Roslyn binary wasn't being copied correctly to the publish directory. It should be fixed if you install Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.7 .

There seem to be some residual issues which are being tracked here .

Answer 2

Same problem accourred to me while publish MVC .NET application to my local path. I solved the problem delete Microsoft.CodeDom.Providers.DotNetCompilerPlatform by nuget package.
