DataTemplates and generic types

Question

I have a generic class

public abstract class BaseViewModel

Since I am trying to create a DataTemplate that will be applied to all clas

Answer 1

I would create a non-generic version of BaseViewModel and let the generic one inherit from it:

public abstract class BaseViewModel
{
    // members that are not T-specific, if any
    // (not required, but could prove useful)
}

public abstract class BaseViewModel<T> : BaseViewModel
{
    // T-specific members
}

By doing this, your DataTemplate is going to work.
