What is dotnet 35sp1?

Hi

In order to run .Net programmed applications, you have to have .Net Framework installed in your computer.

It depends that the programmer programmed with which version of .Net?

.Net Framework's versions are:

.Net Framework 1.0

.Net Framework 2.0

.Net Framework 3.0

.Net Framework 3.5

.Net Framework 3.5 Service Pack 1 (SP1)

.Net Framework 4.0

Usually, a .Net programmer has all of these .Net versions installed in his computer. But, as a client you have to have the .Net version that your programmed is coded by.

Usually, the programmer makes the application installation file equipped with.Net Framework, so it installs on your computer and you don't have to do anything more.
