class Foo{}
Foo obj = new Foo();

Before an instance of Foo is created, CLR will look up the loaded type, in this case it will look for the type Foo to see, if it exists. If Foo type is not loaded, it will load the type and get the MethodTable address. It will create the object instance and populates the object instance with the TypeHandle value which will be the pointer to the just obtained MethodTable data structure. The JIT complier generated code uses TypeHandle to locate the MethodTable for method dispatching since the MethodSlotTable within MethodTable has the information on type’s method.

Alright so enough about MT, when you want to dump all the objects of a type on managed heap, you get the method table address by executing “dumpheap -type ” . once you have the method table address, you can execute ‘dumpheap -mt ” to get the objects on managed heap
