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!
