c# - Overwrite settings file in test project -

I love versus settings.settings tools vs. I like a type of safe, which I have given the name to get the prescribed variable, are you there? The biggest problem with me when moving forward from General AppSetting / Configuration Manager is that I need my test project to overwrite those settings

It seems that when I try the settings.settings file in the test project I do not overwrite the settings.settings file in the main project. Can I complete this anyway?

In addition, I am using a web project, which means that I have to configure from the web. In the main project from config, but download them from an app. Is this change any of the config exams?

If I'm not mistaken, then the settings should be explicitly saved, Is done through the Save method.
