I am working on upgrading my VS2008 Silverlight 3 application to VS2012 Silverlight 5. I have everything compiling, except that when I go to run it in debug mode, I get the error:
0x800a139e - JavaScript runtime error: Unhandled Error in Silverlight Application
Code: 2103
Category: InitializeError
Message: Invalid or malformed application: Check manifest
I have seen all the different posts about making sure the Startup object is set and everything, and it is. So I have some other issue. One thing is that isn't super normal is that the application is international.
The application is of no value without the backend, so anyone that would be willing to look at this, I would be happy to send you the whole project.
