i am using visual studio2010. i am facing a problem that when i create a new web project then visual studio makes project and don\'t show its solution in solution explorer. And
you can make the solution always show by Options dialog
Essentially you should follow this link to create a new solution:
http://msdn.microsoft.com/en-us/library/zfzh36t7.aspx
It also tells you how to add existing projects to new solutions is well. There really isn't that much to it.
Your issue isn't you cannot see the solution. It is that you have created a project only and not a solution. So I would create a new solution and then add existing projects to it.
Also as mentioned by @Devjosh in the comments when creating a new project you can say create new solution with the checkbox.
