Question

Now is time to write all for web-based applications? Write web applications is slower than winforms-based applications?

When to write web based and when to write desktop based?

Answer 1

You should write all your applications with the logic in a separate layer so that you can easily write a web interface or a winforms interface depending on changing business decisions.

On a more serious note. You should create a web application when you need lots of users accessing and changing lots of shared data. You should build desktop apps when there is very little shared data, or when the sharing of data is simple enough that emailing files back and forth is sufficient. Web applications are usually a lot more difficult to get right, so you should only take on the extra work if necessary. It’s a lot more work to to the programming right, and it’s a lot more work to maintain the application server and database. However, web applications are instantly updateable, so you can start with something small, and everybody using the application can get new features and fixes as they are finished. So you have to decide which is more important. There are a few trade offs no matter which you choose.
