Open project / solution will open a .csproj file which contains a list of the files included in your projects, among other settings. Website is just a folder with files / subfolders in it. You can't control which files are included , it just take the whole base directory content.

It's the difference between a web project (aka web application) and a website.

A website in visual studio doesn't have an associated project file - it is just a collection of directories and files. Everything in it is part of the site.

Open Website: Here you do not need to create a associated solution file.

Open Project Here you can create a solution and in one solution can add many projects or websites. when you open solution then it will load all projects and websites that are included in solution.
