Visual Studio 2017 bin\roslyn files locked during build

Question

I am running VS2017 version 26430.13 and every time I try to build a web project I get errors that access to the files in the bin\\roslyn is denied. Over a period of about 5 mi

Answer 1

I have VS 2017 Enterprise and for me the issue was resolved by this:

1. Downgraded Microsoft.Net.Compilers from 2.3.1 to 2.3.0
2. Downgraded Microsoft.CodeDom.Providers.DotNetCompilerPlatform from 1.0.5 to 1.0.4.
