Hi bper_dlt,
Welcome to the MSND forum.
If the folder has a .sln and .suo file, you can double cilck .sln to open that solution. So I'm a little confused about your issue. If you want to build a new project in your folder, you can try to build the project and change the location to your folder.
Then Add-> Existing Items to your project so that you can add files into solution explorer.
Please show us more details about what you need , maybe you can show us some screenshots to describe.
If you have any udpates, please feel free to let me know.
Best regards,
Barry Wang [MSFT]
