Recently I completed my Btech and I got a job as dot net developer. I have a visual studio 2010. I removed it from my computer and then I re installed it. This time visual studio 2010 software is asking that you do not have microsoft .net framework 4 in your computer. So I have to download it from internet but the main problem is Microsoft is asking for money to download microsoft .net framework 4. I want a website address which will provide me free of cost.
