		<title>Tools - Part 8 - Add-ins - “Model First” in Entity Framework</title>
		<description><![CDATA[In Tools Part 6 I covered SQL-DDL generation from Linq-to-SQL models using Huagati DBML Tools. The L2S version is incremental, meaning that it compares the L2S model to the underlying database and generates the DDL code necessary to change the database to match the model. This is effectively a reverse implementation of the update/sync feature [...]]]></description>

		<title>Offtopic: Thanksgiving, the turkey holiday&#8230;</title>
		<description><![CDATA[Since I&#8217;m not American, and I don&#8217;t live in America I normally don&#8217;t celebrate American holidays. However, I really like eating turkey so when I bought some food this morning and happened to pass a bunch of turkeys I decided to make an exception and roast a turkey. So I guess that technically makes me celebrate [...]]]></description>

		<title>Tools - Part 7 - Add-ins - How to deal with the Entity Framework designer and orphaned entities</title>
		<description><![CDATA[A problem frequently plaguing those brave enough to us the Entity Framework v1 is mapping exceptions. Whoa, that sounds negative. But the fact remains: it relatively easy to use the EF designer to turn the model into something that will throw a MappingException error at runtime.
In short, the cause of this is that despite EF being [...]]]></description>

		<title>Architecture - Linq-to-SQL and set-based operations: Delete statements</title>
		<description><![CDATA[A few weeks back I published a code sample showing an implementation of set-based update operations using Linq-to-SQL. I also promised a followup showing batch deletes, and &#8220;insert into&#8230;select from&#8221; so I guess it is time for a followup. This time I will cover set-based deletes.
To avoid unnecessary duplication the code in this article is [...]]]></description>

		<title>Tools - Part 6 - Add-ins - &#8220;Model First&#8221; in Linq-to-SQL (and Entity Framework)</title>
		<description><![CDATA[A question frequently asked on community sites such as stackoverflow.com and in the MSDN forums is &#8220;how do I generate DDL scripts with model changes&#8220;. Translated: some people want to use a model first approach with the Linq-to-SQL designer or the Entity Framework designer as the modelling tool.
This is a nice idea that I absolutely [...]]]></description>

		<title>Data Model - Basics - Part 11 - The HuagatiRes data model converted to &#8220;M&#8221;</title>
		<description><![CDATA[Happy over Microsoft&#8217;s new commitment to data modelling, I have been playing around a bit with the &#8220;Oslo&#8221; CTP. It is time they come up with a replacement for Visio 2003 EA. The latest thing I tried was a conversion of the HuagatiRes datamodel into an M script. There&#8217;s not much to say about it - [...]]]></description>

		<title>Architecture - Linq-to-SQL and set-based operations: Update statements</title>
		<description><![CDATA[Data manipulation with OR mappers usually ends up with records being to be pulled back from the database to the business logic tier or client, changes applied and record-based update statements generated by the OR mapper and sent back to the db server. This is fine when working with a small number of records or when the data [...]]]></description>

		<title>Quiet blog, gone fishing, is Linq-to-SQL dead?, etc</title>
		<description><![CDATA[It has been a while since I posted anything on the blog. Did I stop blogging? Nope, just been having fun with other stuff. Like optimizing indexes for an oracle database, adding new features to my L2S/EF toolkit etc.
Gone Fishing
Right now I am &#8220;busy&#8221; fishing. It is Sunday and we&#8217;re at our vacation house on the [...]]]></description>

		<title>Tools - Part 5 - Add-ins - Documentation features in Entity Framework vs Linq-to-SQL</title>
		<description><![CDATA[EF Designer - Documentation Features
A couple of weeks ago I mentioned that the ADO.NET Entity Framework designer has a new documentation field that allows entity types and members (classes and properties) to be documented right in the designer.
I think this is a useful feature - once descriptions have been typed in for all classes and properties, the code editor [...]]]></description>

		<title>Tools - Part 4 - Add-ins - Adding functionality to the Entity Framework EDMX designer</title>
		<description><![CDATA[After playing around a bit with the ADO.NET Entity Framework designer in Visual Studio 2008 SP1 I was a bit disappointed with its&#8217; user friendliness (or lack thereof). I guess this can be read between the lines in my previous entry on EF.
Instead of waiting for the next service pack for Visual Studio I figured it is more constructive to [...]]]></description>
