designing an application in winforms ????

[Mahesh Kumar.R]

I'm into designing an application in winforms but in near future my client may request the same thing in webforms. so

(1) what are all the design guidelines and ways are there to migrate easily in future (winforms -> weforms)...?

(2) how can i design my application which can be accessed in both winforms and webforms by not writing much of code for the same business logic. ?

(3) which is the cost effective method ?

Please guide me to design in such way that (1) I can migrate easily (2) I can run winforms and webforms parallely
Thanks,

The basic concept is to separate out the presentation logic from the
business
logic. The key is that the business logic knows nothing of the
presentation
implementation. eg don't pass a textbox to the business logic.

If you use an n-tier architecture, using well established design
patterns (look up Gang of Four, Patterns of Enterprise Application
Architecture - Martin Folwer). You can use an architecture which will
allow you to completly seperate business and data logic from the
presentation. If your client wants a web front end all you need to
develop is a the front-end your back end should be completly re-usable.
When you are developing the windows form application you could use web
services to allow the client to communicate with the server making the
backend code web-enabled and ready for developing the web front end at
a later date.
Hope this helps.
