Say you are creating new Windows Application Project using Visual Studio 2010,
the project created successfully but I am unable to see the solution created in
the solution explorer window due to this I am unable to add another project to
the existing solution.
Finally I got the Solution and fix the issue, please follow the steps to fix
this issue…
Step1: Open Visual Studio 2010, and select Menu Tools -> Options
Finally I got the Solution and fix the issue, please follow the steps to fix
this issue…
Step 2: Now go to Projects and Solutions -> General section in the tree view on left side of options window and check the checkbox “Always show solution” as shown below
That's it now again try to create the project you will be shown by the solution
so that you can add as many projects you can.
