Background: I had Microsoft.CodeDom.Providers.DotNetCompilerPlatform 2.0.1' and tried to upgrade to the the newest version 3.6.0 in Visual Studio 2017 in my web project using the Nuget package manager and get the error:
Could not install package 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform 3.6.0'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any assembly references or content files that are compatible with that framework. I tried to go back to the version 2.0.1 and it won't install that now either, even though that was the version that was installed before I tried to upgrade. I can uninstall all of it, but then I 'think' I am not using the Roselyn compiler (do I need to?).Any help would be appreicated either to get the newest version installed, get 2.01 installed, or a clear answer that I don't need the Microsoft.CodeDom.Providers.DotNetCompilerPlatform package. Thank you!
