Visual Studio Solution shows (0 projects)

All I had to do to get this working is I had to right click the project and click reload project. Somehow my project got unloaded. When your circumstances look like this, it is possible that this happened.

try this:

• right click on the solution name
• select 'Add'
• select 'Existing Project'
• in browser window go to your project folder and select 'YourProjectName.csproj' file (.csproj file of project)
• and the project will be added! so Done!

Best Regard.
