Can I make add on for RMS using .Net ?

Of course you can. I know for sure it can be done in Vb.net so I imagine C# would be the same of course with different syntax. If you know .net enough the code in the customisation guide should be easily translated into C# code.

Hope this helps

Thanks a lot, yes this has helped me a lot... Just want to know other than being a RMS partner is there any other way to get customisation guide ??

Thanks >
