Change Application.ResourceAssembly in WPF?

This is a question that puzzled me.

In beginning, Application.ResourceAssembly is null;

Application.ResourceAssembly = assembly1;  // it's ok
Application.ResourceAssembly = assembly2;  // It will has a error.

A first chance exception of type 'System.Xaml.XamlObjectWriterException' occurred in System.Xaml.dll

So, can Application.ResourceAssembly be assigned if it isn't null??

The problem is that you are trying to set Application.ResourceAssembly twice. You can only set it ONCE.

Here is the MSDN quote from Application.ResourceAssembly Property page:

ResourceAssembly can only be set once because it is unlikely that the resource assembly will change after the WPF assembly is loaded.
