Someone asked me if I had a simple sample of how to read/write documents into a database table using FILESTREAM in SQL Server 2008. I set about it. Firstly, I had to find out how to switch FILESTREAM on in the RTM of SQL Server. At times like this you Read More...
I produced a new set of short videos around ADO.NET Data Services and dropped them on to Channel 9. You can find them here; http://channel9.msdn.com/tags/UK and that list will grow as time goes in ( specifically, it'll grow if I can get the publishing Read More...
This is similar but not at all identical to this post about LINQ to SQL because it's using a different framework and that has different capabilities. Someone mailed and asked how we can detect concurrency problems with Entity Framework in order to ensure Read More...
I came across a bit of a glitch in using timestamps for checking concurrency violations in LINQ to SQL and thought I'd share. Say I've got a table like; create table Person ( id int identity primary key , firstName nvarchar(30), lastName nvarchar(30), Read More...

Something that I came across today - if you're trying to surface a LINQ to SQL data source via the latest build of ADO.NET Data Services and you're running datasvcutil.exe on the metadata of the service then you might find yourself with a whole bunch Read More...
