compile this program with gmcs, and run pedump --verify code on the resulting
assembly. THe verifier will reject it saying:
Error: Invalid generic type instantiation of type .SerializerItemProxy`2
(generic args don't respect target's constraints) at 0x0000
While MS's peverify thinks it is fine.
public class SerializerItemProxy<TBaseClass,TActualClass> :
SerializerProxy<TActualClass> where TBaseClass: class where TActualClass:
class, TBaseClass
{
}
public class SerializerProxy<T>
{
static SerializerProxy<TItem> MakeItem<TItem>() where TItem:class,T
{
return new SerializerItemProxy<TItem,TItem>();
}
}
