Hi Paul,

Yes, Visual C++.NET does not implement partial template 
specialization or full Koenig lookup. 

However, several conformance-related and other issues have been 
resolved that may be of interest to library developers:

Q240862 BUG: C2555 On Virtual Functions with Covariant Return Types
Q240871 BUG: Explicitly Specified Template Functions Not Overloaded 
Correctly
Q241569 BUG: C2258 and C2252 on in Place Initialization of Static 
Const Members
Q241706 BUG: C2123 on Function Try Block Syntax
Q241940 BUG: C2954 on using class template as template parameter
Q242192 BUG: uncaught_exception() Always Returns False
Q243444 BUG: CSTDLIB Does Not Define the Namespace STD
Q167733 PRB: Operator New Doesn't Throw bad_alloc Exception on Failure
For loop variable scope
void return type
standard names added to std
aggressive inlining
debugger and STL types
conformance of header files and standard library
memory allocation diagnostics
template template parameters
member function template arg specification support.

The results of the survey so far have been discussed by the team.
We are actively addressing issues mentioned, and continue to be most 
interested in feedback from library developers and users.

Best regards,

David Wolfram
Visual C++ Compiler Team
