用于测试/生产版本的EF6连接字符串

Question

I'm sure this sounds familiar: An application is in production and connects to a live database. Meanwhile, the next version of that application is used by developers (their own executables and a development database) and testers (test executables and a test database).

In EF6, the connection string is either specified in app.config or passed in as a parameter to the DBContext constructor. Whenever a test version is released, I need to manually replace that app.config (or the connection string) with the test version and the same needs to happen when we implement.

It seems there must be a better (automated and less risky) way of doing this, but I have not figured out what that would be. Am I missing something elegant and built-in, or is there a best practice that I should know about?

You can use XSLT transformations, or SlowCheetah . Personally I've only used XSLT transformations, and the only thing was that the app.config needs to be writeable which didn't work nice with TFS in commandline local builds.
