I need to develop a forms application with a DB backend. In future this may be linked to ASP.NET page. I was thinking of doing this as an MVC and reuse later.
So, What kind of MVC frameworks do you use?
I am interested in building forms quickly and any frameworks that link/bind control to database fields.
In my knowledge there isn't a specific mvc framework for winforms, as for web applications (mvc2) . You'll have to implement the mvc (or better mv presenter) pattern by yourself. See this link http://msdn.microsoft.com/en-us/magazine/cc188690.aspx
MVC is really only a pattern to structure your code around.
If you are really going to take your app and port it to be available over the web later on then may I suggest that you code it as a WPF application using the MVVM pattern as this will involve less work in the long run.
Alternatively if use ASP from the start.
There are no really famous MVC frameworks for Windows Forms. There is probably a good reason for this - it's really difficult to implement MVC with Windows Forms due to the nature of the technology. I think you're much better off using MVVM with Windows Forms and I'm saying this as a huge fan of MVC.
Otherwise you need to give us more details of what you're doing and then we could probably offer some better advice.
