How to add 'src' folder at solution root : <p>This is going to sound like a silly question, but Visual Studio does not seem to let me do this simple organization which I see all the time on github.</p>

<p>I start with new empty solution.</p>

<p>I then want to add a "src" folder which will contain project multiple projects.  If I right click and select "Add Folder" VS adds a virtual folder, not an actual folder.</p>

<p>If I use Windows Explorer to create a new folder in the desired location, VS ignores it and does not let me "Add to solution"</p>

<p>If I add a project, it adds the project at the root, not in the desired folder.  </p>

<p>So, how do I add this folder?</p>
