I chose VisualStudio2013 theme, I click "Configure Project" on my project, chose controls and theme, after that, it appears strange error:

"Object reference not set to an instance of object" highlighting Application tag. Why?

Hello Dario,

I can suggest you clean and rebuild the project. Since you are changing dependencies, this can happen.
furthermore, you can try manually cleaning the content of the obj and bin folders of the project, clean and rebuild.

This error is actually non-breaking, and it should get resolved after cleaning that cache and restarting VisualStudio. You need not worry about it.
