Question

I am trying example from this page, but get the error:

Error   1   The type or namespace name 'MarshalByRefType' could not be found (are you missing a using directive or an assembly reference?)  C:\Dropbox\development\snipplets-examples\dot.net\appdomain\MyAppDomain\MyAppDomain\Program.cs  34  13  MyAppDomain

Code:

// Create an instance of MarshalbyRefType in the second AppDomain. 
// A proxy to the object is returned.
MarshalByRefType mbrt = 
            (MarshalByRefType) ad2.CreateInstanceAndUnwrap(
                exeAssembly, 
                typeof(MarshalByRefType).FullName
            );

Answer 1

The definition of the MarshalByRefType class is given in the page you’ve linked.
