+- Method signatures with pointers aren't supported.
 
-2. Sealed classes or static methods can't be stubbed because stub types rely on virtual method dispatch. For such cases, use shim types as described in [Use shims to isolate your application from other assemblies for unit testing](../test/using-shims-to-isolate-your-application-from-other-assemblies-for-unit-testing.md)

 ## Change the default behavior of stubs
 
-Each generated stub type holds an instance of the `IStubBehavior` interface (through the `IStub.InstanceBehavior` property). The behavior is called whenever a client calls a member with no attached custom delegate. If the behavior has not been set, it will use the instance returned by the `StubsBehaviors.Current` property. By default, this property returns a behavior that throws a `NotImplementedException` exception.

 The behavior can be changed at any time by setting the `InstanceBehavior` property on any stub instance. For example, the following snippet changes a behavior that does nothing or returns the default value of the return type: `default(T)`:
