Recently, i had a very interesting problem with my colleague, we were unable to see the sln file in his Visual Studio 2010’s Solution Explorer. He was unable to add another project into the solution. We tried to open and close the solutions and alot different ways….

Apparently, what we have to do is just to go into Tools > Options in Visual Studio and go into Projects and Solutions and select General. There is an option called “Always show solution“. Check it and save and you will see your solution file!
