Visual Studio Hosting Process and “The operation could not be completed”

by

The problem with turning off this “hosting process” is that all the “run and rewrite” functionality is no longer available.

The Visual Studio Hosting Process is not needed to allow Edit and Continue. It is used for “Design time expression Evalutation” in the case where the project is a dll rather than an EXE. It is also used to provide debugging for partial trust scenarios. See the documentation for everything it does.

It is highly unlikely it does anything you need, so don’t feel bad turning it off.
