LicenseInitializer leaks memory when call are made to a SQL server using LINQ.
The code below leaks finalization handles, one for each data context created. I believe that the esri licence system is listening for database connection events and firing an event handler. I expect this is required to check licencing of SDE databases. The SQl server I am using does not have an SDE, it is a vanilla MS SQL server, Evidently the fired event handler creates a number of objects that are not finalized/disposed correctly and accumulate in memory as they can't be garbage collected.
Adding a "GC.WaitForPendingFinalizers();" in the for loop, after the DataContext has been destroyed seems to release the offending objects but this is computationally expensive.
I believe this is a bug in esri's licencing system. Has anyone seen this previously.
Thanks
Steven
