"The Visual Studio hosting process improves debugger performance and enables new debugger features, such as partial-trust debugging and design-time expression evaluation"
In real world:
Sometimes, vshost.exe always running, and you can't even kill it from Task Manager. (After killed it, it restores automatically, need to quit Visual Studio)
Need to disable this feature/bug by following steps:
Properties of project =>
"Debug" tab =>
uncheck "Enable the Visual Studio hosting process"
