Is their any way to call DCOM server methods from WCF Services?

but i want information regarding conversion of COM application to WCF. My application consists of lots of C++ files.   AFAIK, there is no "built-in" tool to change the C++ files to WCF compatible classes/files. You need to rewrite it (either C# or VB.Net) after understanding the logic of C++ files.

You need to decide, which functions are need to be move first to the web service. Then start your coding accordingly. For a basic Webservice tutorial:   http://www.codeproject.com/Articles/337535/Understanding-the-Basics-of-Web-Service-in-ASP-NET     Also i would, suggest that instead of converting normal webservices, you can migrate your COM to WCF, which provides lot more flexibility than Webservices.   http://www.dotnet-tricks.com/Tutorial/wcf/cH1H200314-Difference-between-WCF-and-ASP.NET-Web-Service.html     Hope this helps!
