System.InvalidOperationException: Timeout expired exception in EPiServer 7.5

by mstrid on May 15th, 2014

Today I encountered an exception when developing a new site based on EPiServer 7.5 CMS:

Timeout expired.  The timeout period elapsed prior to obtaining a connection from the pool.  This may have occurred because all pooled connections were in use and max pool size was reached.

The cause was very simple but maybe not that inutitive, I had used the wrong connection string. Maybe this short blog post could help someone else.
