Now, I see that PGO will not be supported in the express products :-(. I realize that PGO is not going to make a huge difference, but an additional 20% aer always appreciated in board game prog ...Show All

  WinFX is now .NET Framework 3.0, does this mean Linq is also 3.0 or will it be 4.0 or ... I won't be surprised if in future Microsoft renamed LINQ to ADO .NET 3.0, as .NET 3.0 is the name officially reserved for WinFX (Indigo). As said by one of our FRIEND ( Mark Blomsma)  in his previous post that LINQ might get renamed to C# 4.0, I feel it will not be possible because LINQ support has alread ...Show All
