    This software does not compile due to the use of “List”, according to the compiler, “Using the generic type ‘System.Collections.Generic.List’ requires ‘1’ type arguments”

    I am not familiar with C# and I’m having difficulty with this particular code. Specifically, with the private List _observer declaration. Should that be of some form List? I really do not know what to do with it and can’t seem to find the answer anywhere.

    such as List ?
