Hello, It seems that the source code mostly uses contracts pre and post-conditions of the form: Contract.Requires(x != null); Is it a deliberate choice to limit yourself to such kind of simple...

Hi vaucouleur, Good point. Contracts was originally introduced as a way to replace our hand-rolled pre-condition checks. But we recently discussed this as a team and decided to extend our use of...

Hi Dwin, Sorry for taking some time to get back to you. I can see no real reason why this cannot be made public if it is needed to make the Power Tools change work efficiently. Thanks,Arthur

Hi XIU, Thanks for the additional info. I'll bring up the idea of making ObejctContext implement IObjectContextAdapter with the team and get back to you. Thanks,Arthur

Hey guys I did a few tests around the comparative performance of the different SQL insert methods which show up some of the details around Query Plan calculation, SQL bulk copy and how all of this...

Hi Luke, That's some great information. One thing I'm curious about is how these numbers change as the latency between the app and the server increases. What is your current setup in terms of where the...

Hey Arthur Yeah those tests were to a machine less than a millisecond away (on local gigabit). Ill grab a latency generator and try a few more scenarios, we use a few for work already as NZ is a long...

Hey Arthur I've done a few tests around how latency affects insert performance and the results are about what you would expect, IE when you batch multiple statements into a single statement or...

In all honesty, who's going to insert 10K rows over a 100ms latency connection? Be aware that batching only has benefits in bulk inserts.

Hi Frans I can tell that you do not want to modify the query generation for Entity framework, however I am unsure why you are so concerned about the proposed modifications. When testing often its...
