While I was working on some code today and found that some NuGet packages where out of date. So I went to update tab in Manage NuGet packages window and updated all of them. MySql.Data package (not important which package, just an example) was also updated in that from version 6.7.8 to current / latest (6.9.6). I tried to run the application to test the updates made in referring packages. I encountered following error: TypeInitializationException was unhandled An unhandled exception of type 'System.TypeInitializationException' occurred in Unknown Module. Additional information: The type initializer for '[Application Name]' threw an exception. Looking at this exception, it doesn't seems to be obvious what is going wrong here.

Did you encountered following exception / error when trying to run ASP.NET MVC web application? The view must derive from WebViewPage, or WebViewPage or Type 'ASP._Page_Views__ViewStart_cshtml' does not inherit from 'System.Web.WebPages.StartPage'.
