| Any WinForms books? (3 replies) |
| microsoft.public.dotnet.general |
| Hi, Could anyone recommend a good book that focuses on WinForms? Most of the ..NET books that I've seen are very broad explaining what the CLR is, how assemblies work, and how .NET compares to Java. I'd prefer a book that gives an in depth description of WinForms... I might be asking a bit much, since the product is still in Beta... but just thought I'd ask. David |
