Entity Framework - SQL Azure Retry Policy

Question

Could anyone guide me how to implement a retry policy with EF to SQL Azure, please.

This Azure Forum thread has some links to good resources that cover this topic. There doesn't seem to be anything 'official' quite yet. But there are some open source projects that give you a pretty good start.

I personally didn't use the library the blog mentions. Instead I was able to get away with a simple WHILE LOOP with a TRY/CATCH that watched for the specific SQL EXCEPTION Error Numbers which were safe to retry. There is also a counter which basically prevents it from 'retrying' forever.
