How to properly include app.config

Hello,

i am trying to use the Entity Framework in one of my EB Plugins. The Framework stores the configuration in an app.config file in the projekt. Now when i start the Plugin in EB and try to connect to the database i get the exception that the app.config file could not be found. Same goes for other frameworkes which depend on .config files (eg. Nlog or so).
I tried several things in the build config / assemblyobtions but none of them are working.

What am I missing? How can i deploy the app.config file? Has anyone experience with that kind of issue?

thanks
