This code:
Type.GetType(\"namespace.a.b.ClassName\")
returns null.
and I have in the usings:
using nam
You can also get the type without assembly qualified name but with the dll name also, for example:
Type myClassType = Type.GetType("TypeName,DllName");
I had the same situation and it worked for me. I needed an object of type "DataModel.QueueObject" and had a reference to "DataModel" so I got the type as follows:
Type type = Type.GetType("DataModel.QueueObject,DataModel");
The second string after the comma is the reference name (dll name).
