Dealing with SPUpdatedConcurrencyException

SPUpdatedConcurrencyException is an exception thrown by the SPPersistedObject Update() method. It indicates that another processes has updated the SPPersistedObject you have just modified and are trying to update.

I have found that best practice is to wrap all calls to Update on any SPPersistedObject to iterate until successful. Of course it is folly to iterate forever, so I have my code give up after 10 tires. Here is a snip:

int count = 0;
while (true)
{
    try
    {
        MySPPersistedObject obj = FindMyObject(id);
        obj.SomeOperation();
        obj.Update();
        break;
    }
    catch (SPUpdatedConcurrencyException)
    {
        count++;
        if (count > 10)
        {
            throw;
        }
    }
}
