Does Entity Framework/LINQ to SQL Implment ITypedList?

As I looked into the ITypedList interface I realized that perhaps everything I needed was already implemented as my business objects are generated by Linq-To-Sql? The answer turns out to be “sort-of”.
I’m taking a peek at both the Entity Framework and LINQ to SQL, and while I like the systems (and of course the LINQ [...]

EDMX Issues With Visual Studio 2010 Beta 1 to Beta 2

Scenario: Important meeting! Too much coffee! Bad lighting! In walks the killer! Wait…
No, that’s wrong. In walks Visual Studio 2010 Beta 2 with an inability to open an EDMX created with Visual Studio 2010 Beta 1, asking if I’d like to open the file in an XML editor. Ack! A previously printed paper diagram (for [...]

SqlCommand Timeout Exception with ADO.Net Data Services

When my ADO.NET Data Services web service started throwing SqlCommand timeout messages I hit up Google and finally found a post in German(?) that pointed me in the right direction.

InitializeService in ADO.NET Data Services

Need to debug an ADO.NET Data Service?
Another interesting point has to do with error handling. The option for error handling is set during InitializeService.

Sybase working to improve NHibernate support | Elegant Code

NHibernate keeps looking more and more like the enterprise .NET solution to choose…
But support in NHibernate for Sybase is not great. The basics work but some of the more advanced features are not implemented at all or are done poorly. Fortunately we have an excellent relationship with our vendor and have had for many years. [...]

xSQL Profiler – Free Sql Server Profiler

One of my biggest complaints about the Express versions of Sql Server is that Sql Profiler is specifically excluded, a full Sql Server license is required instead. I managed to do without Sql Profiler just fine until I was working on some Entity Framework code and wanted the see the sql getting generated. It certainly [...]
