• stephen terapak What is the proposed way to define references in .NET?

  Status ------ Currently we use two different methods to define references between managed components, namely project references and .NET references to reference assemblies (details below).  Both methods are not fully satisfactory.  We would like to know: (a) Is there is a better referencing mechanism available in VS8 (better than the ones described below), or (b) does MS plan to change the support for references in future versions of V ...Show All
