Project builds but can't publish

Question

I have an MVC project that for an uknown reason refuses to publish to a local folder in the PC.

The log says the following:

3>------ Publish started: Project: Admin, Configuration: Release Any CPU ------ 3>Connecting to D:\Deploys... 3>Project "Admin.csproj" (GatherAllFilesToPublish target(s)): 3>    Building with tools version "14.0". 3>    Target "ValidateMSBuildToolsVersion" skipped. Previously built unsuccessfully. 3>Done building project "Admin.csproj" -- FAILED. 3> ========== Build: 2 succeeded, 0 failed, 1 up-to-date, 0 skipped ========== ========== Publish: 0 succeeded, 1 failed, 0 skipped ========== 

I haven't had a problem debugging on either release or debug config.

Answer 1

So I made it work.

The problem was the version of the "Microsoft.Net.Compilers". I downgraded from v2.6.1 to v2.4.0.

I don't know why so if someone knows it would be cool to know.
