DbProviderFactories and machine.config in Framework/Framework64 fun

11 Sep 2012 1 mins .NET, Firebird, Life

Fun today. I was trying to use FirebirdClientFactory from FirebirdClient installed in GAC. Because it was used globally I was not editing app.config/web.config but machine.config. I went to Framework etc. directory and modified machine.config. And … and it still wasn’t working. Fast forward, I spent maybe an hour trying to figure out what’s wrong. I was hopeless. Everything seemed fine. Randomly cd-ing through directories and thinking what I’m missing, I realized I didn’t modified machine.config in Framework64. Stupid mistake.

Sure after I corrected myself everything started working. Hope my story will save you time.
