Q:

Does MSVC10 Visual Studio 2010 support C++ explicit conversion operators

Does Visual Studio 2010 MSVC10 support explicit conversion operators, or is the safe bool idiom still required to be implemented?
This code does not compile:
  explicit operator bool() const
  {
    return Traits::invalid() != value;
  }

Compiler error:
error C2071: foo::operator bool' : illegal storage class 

A:

No, VS2010 has a very limited C++0x support. Here is a list of features that are supported by VS2010.
