Two great products have turned to RTM/W and available for immediate download. One is my favorite and much anticipated Enterprise Library v5.0 and the other being SQL Server 2008 R2 Express (Standard and Advanced Services editions). Needless to say, Enterprise Library 5.0 is compatible with VS 2010.
Get Enterprise Library 5.0 and SQL Server 2008 R2 Express (Advanced Services) for full joy!!
