Parser Error Message: Could not load type 'XXX.Global'

[yashgt]

I have a web application which has two projects in one solution. The
proper build order and dependencies have been set. The solution
compiles and builds properly. But when I invoke any URL from the
application, I get the following error:
Server Error in '/NSTO' Application.

Parser Error Message: Could not load type 'NSTO.Global'.

Source Error:
Line 1: <%@ Application Codebehind="Global.asax.vb"
Inherits="NSTO.Global" %>

Source File:
C:\TNM-Application\BroadcastRooms\GeneratedMRs\NSTO\globa l.asax
Line: 1
--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.2032;
ASP.NET Version:1.1.4322.2032

The root namespace for the application has been correctly set to NSTO.
What might be the reason behind this problem? What is the solution?

Thanks,
Yash
