About Meta-Me


My name is Alex James, a Program Manager working on the Data Services team at Microsoft.

My current focus is OData and improving the usability of Data Services, both client and server side.

Previously I worked on the Entity Framework team where I helped create EF 4.0, and CodeOnly.

I'm also really passionate about Metadata, hence the name Meta-me.

    Rolling your own SQL Update on-top of the Entity Framework - Part 3
