is there any online training for c# /asp.net via skype ?

Yes one more website which name is www.facetofacestudy.com is there you will able to take online training for C#/asp.net with our personal software which name is whiteboard software.

I personally am registered on that site, however has not started trainings yet. Also I assume since the reviews posted there would be legitimate and you can trust those reviews for choosing the best trainer. Along with it, I guess they have some initial sessions free of cost just to check whether the trainer is competent. Hope this helps !

thanks, i knew this website but want to know any names based on their real feedback from this forum.

Rahul, You can find great trainers on https://www.urbanpro.com/. This website has different options for training locations such as online, class room based, etc... Give it a shot and accept my answer if you think it helped you. Thanks
