Hi,
I am nut sure the problem is with Core. I do asp.net with webpages.
The actual error message is:
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: The CodeDom provider type “Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35” could not be located.
I have upgraded to V4.1.0 from V2.1.0, and there is no other version available
