ConfigurationManager.AppSettings - returns zero

Question

I am trying to read the settings from my app.config and I'm sure that it worked before that, but now it returns a nullReferenceException.

My code getting settings looks like this:

codeValueUtilRx = ConfigurationManager.AppSettings["CODEVALUE_UTIL_RX"].Split(';').ToList(); 

My app-congfig is as follows:

 <appSettings> <add key ="LOGFILELOCATION" value ="C:\\RuleEditor\\"/> <add key ="CODEVALUE_UTIL_RX" value="GCN;GRP;NDC;SPEC;TCC"/> </appSettings> 

I have a feeling, something that seems obvious, I just can not understand it. Ive tried moving app-config to different projects in the solution, and ive recreated the file, but no luck. Any ideas?

your code is correct (I tested), you need to make sure that your app.config file is in your main project (exe).
