How to find path of active app.config file?

Question

I\'m trying to finish this exception handler:

if (ConfigurationManager.ConnectionStrings[\"ConnectionString\"]==null)
{
    string pathOfActiveConfigFile = .         


        

Answer 1

The first time I realized that the Unit testing project referenced the app.config in that project rather then the app.config associated with my production code project (off course, DOH) I just added a line in the Post Build Event of the Prod project that will copy the app.config to the bin folder of the test project.

Problem solved

I haven't noticed any weird side effects so far, but I am not sure that this is the right solution, but at least it seems to work.
