Wrong cached value pulled from cache

[Purtzel]

Hello,

when getting informations for the following two methods:

void Test( int test, bool bvalue );

void Test( bool bvalue = true );

When using ToContextualParameter on the parameter of the second overload, I'll get the information from the second parameter of the first overload which is wrong.
The property information for the parameter of the second method is drawn incorrectly from the dictionary because the cache key is not selective enough to distinguish between the two overloaded methods.
