Completely deleting Visual Studio website solutions
visual-studio, visual-studio-2013
Solution
The reason VS thinks the website still exists is because it's looking at the IIS Express applicationhost.config file.
In VS 2015
Visual Studio 2015 uses an applicationHost.config per solution. There is a a .vs folder in your solution. So the solution has a .vs\config\applicationhost.config file
Prior Versions
Look under `%userprofile%\documents\IISExpress\config\applicationhost.config`. Your old website is still registered under IIS Express, so VS generates a unique name for the new one.
Problem
When I create a new website project in Visual Studio 2013, even after completely removing the directory in Visual Studio 2013/Projects and also Visual Studio 2013/Website, VS 2013 still thinks it exists. As a result, it appends an incrementing index to the end of the solution name: How can I completely remove all traces of the solutions (like unloading a normal project)?
