Failed to successfully launch or connect to a child MSBuild.exe process. Verify that the MSBuild.exe

Question

First time this happens to me.

Ran the build and got this error.

When I rebuild other sln all works fine.

Error 1 The build stopped unexpectedly because of an internal failure. Microsoft.Build.Exceptions.BuildAbortedException: Build was canceled. Failed to successfully launch or connect to a child MSBuild.exe process. Verify that the MSBuild.exe "C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\MSBuild.exe" launches successfully, and that it is loading the same microsoft.build.dll that the launching process loaded.

退出并重新打开Visual Studio为我解决了这个问题。

Answer 2

Just had the same issue this morning. This error usually appears when your system is running low on memory. If quitting and re-opening VS doesn't do the trick, try closing some of the other applications that are currently running. If all else fails try restarting your system.

If you have tried everything in this post (restart, reboot, etc.) and nothing helps. Try Running VS2012 as Administrator and see if that helps.
