InitializeError #2103 - Invalid or malformed application

Code# 2103

Invalid or malformed application: Check manifest

Now what does that mean?

This is not easy to interpret, but is very easy to fix :)

This error pops up because of mismatch in the Namespace at following places:

• Silverlight Project Properties
• App.Xaml.cs
• App.Xaml

So just make it to one namespace and there you are... it starts working!
