Global.asax parse error after minor change and revert to previous version

Question

The project in context is:

• ASP .NET Web Application
• .NET Framework: 4
• Platform Target: x86
• IDE: Visual Studio 2010 Ultimate SP1

Answer 1

Regular ASP.NET Web Application has 2 files in solution folder:

1. Global.asax
2. Global.asax.cs

Make sure that class in Global.asax.cs:

namespace YourWebAppNamespace
{
  public class MvcApplication : HttpApplication
  {
     ...

Has the same/right name in Global.asax:

<%@ Application Codebehind="Global.asax.cs" Inherits="YourWebAppNamespace.MvcApplication" Language="C#" %>

I got an issue with this when I manually changed class name in Global.asax.cs file, so as for result I had the same error as you and from my perspective, it should be more informative. I know that this question already was answered, but maybe my case can be helpful for someone.
