Tom Hollander sent out a note this morning soliciting input for the next version of Enterprise Library. So, what would you like to see in EntLib going forward? New blocks or changes to existing blocks to take advantage of some of the new capability in .NET 3.0? Improved performance? New providers? Better documentation? More bling?
Personally, I'd like to see better design-time support for each block via DSLs, and perhaps some investment in a Software Factory for Web Clients. There's been quite a few suggestions posted already as comments to his post, so be sure to check them out.
