> I want to learn asp.net and C#. I donot know how to start and what books to buy. I don't want to end up buying some tough and not easy to understand books. Can we download some free programming language to start with or I need to purchase the programming languages. Please guide.

Hi Bharat. I would consider the following

1) Try out the free videos at http://www.learnvisualstudio.net/ and if you like them sign up for a membership and get the rest.

2) Download the sample chapter of ".NET For Visual FoxPro Developers" http://www.hentzenwerke.com/samplechapters/scnetvfp_2_8.zip
If you like it you can buy it from here http://www.hentzenwerke.com/catalog/netvfp.htm

3) You can buy Visual C# For $87, http://www.amazon.com/exec/obidos/tg/detail/-/B00008I9K3
If you like it and want more features, you can move onto the more expensive Visual Studio

I'd be hesitant to recommend the free Web Matrix since it is different that Visual Studio.
