MVVM Light “Type Not Found in cache”

Question

I\'m trying to convert my Windows Phone 8 Silverlight application to an 8.1 Phone app as part of a universal app. I don\'t know if thats relevant because this is the first t

Answer 1

In my case, the target class didn't implement a parameter-less constructor. The only constructor that the class contained accepted a byte type parameter, so I was getting:

Type not found in cache: System.Byte

My registration line was like this:

SimpleIoc.Default.Register();

I added a parameter-less constructor to MyConcreteClass and then applied [PreferredConstructor] attribute to it (this attribute is available in GalaSoft.MvvmLight.Ioc namespace) and got rid of the issue.

Hope this helps someone down the road.
