i have a general question. I want to develop a Web Application for business process modelling. The application was build using c# and WPF as Desktop Application Software and now i would like to develope it as Web Application. what technology should i choose?
I’ve tried to find it myself but there are many different opinions about that topic. Is there any general rule or methodology which can help me decide?
Your question is not quite constructive. You need to talk to some Architect to understand your business and the requirements to fill up the gaps of choosing a technology. It is quite vague to answer your question whether to choose ASP.NET webforms/MVC or probably a different platform than .NET to suit your needs.
On a general answer, if you are planning to port your whole application developed on desktop using WPF, you can consider porting to Silverlight which might cut down your cost to 90% (probably), where you will able to reuse all codes you have written so far. But that’s totally your call and your business needs.
