ORM Profiling Tools for the .NET Platform

Sadly the terms “ORM” and “performance problems” often travel together. By hiding the underlying SQL from the developers, ORMs can offer a huge productivity boost. Unfortunately they also make it easy to generate ridiculously bad queries without realizing it. And without stored procedures to cross reference, finding the offending code without an ORM-specific profiler can be quite tricky.

ADO.NET Entity Framework Providers for Oracle

Microsoft’s vision for .NET is a wide one. In addition to support for all programming languages, MS wants to bring together all communication frameworks and data storage engines.

LINQ to SQL, The Next Step

by Jonathan Allen on  Dec 04, 2008 4

Despite the numerous problems with Microsoft ORMs and the plethora of alternatives such as LLBLGen, nHibernate, and OpenAccess, many developers are forced to use Microsoft tech because that is why their company or customer wants. And between the two offerings, it seems most developers believe that Entity Framework is not a viable option. So what are they do to?

No Change Tracking for ADO.NET Entity Framework 2010

by Jonathan Allen on  Nov 24, 2008 2

One of the biggest complaints about ADO.NET Entity Framework was that it did not support change tracking. Despite everything from ADO.NET DataSets to every single non-Microsoft ORM having support for this out of the box, Microsoft has no intention of fixing this in the .NET 4.0/VS 2010 timeframe.
