And that’s a rap. The 2010’s Most valuable Professional Summit is now over. It took place in Bellevue & Redmond, Washington, and for those who couldn’t be there for all the good stuff in the agenda, well, eyes wide open for blogs, tweets and streams.
In the meantime, get yourself on the run for that distinguished MVP title and get your ticket to next year’s summit as well as your trophy-kit. The girls will love it… I guess :o)
Next, on April 12th, Microsoft will be pairing with DevConnections for the Visual Studio Launch at the Bellagio Hotel and Casino...

Microsoft released MSXML 4.0 Service Pack 3. MSXML SP3 Core Services are a complete replacement of MSXML 4.0, MSXML 4.0 Service Pack 1 (SP1) and MSXML 4.0 Service Pack 2. MSXML 4.0 SP3 provides a number of security and reliability bug fixes:
Max Element Depth
MSXML4.0 SP3 supports using MaxElementDepth to limit the element depth of an XML document to be loaded into a DOM object. A zero (0) value means no limits on the element depth of an XML document. A non-zero value specifies the maximum depth. The default value for MSXML4.0 SP3 is 5000.
This property helps to avoid denial of...
Microsoft released today the .NET Framework 3.5 SP1 GDR (General Distribution Release). This release addresses some issues and should only be installed if you have some kind of issue. Otherwise, it is not recommended to do so. You better wait.
In case you don't know what a GDR is, here's a quick explanation:
A GDR addresses an issue that has a broad customer impact, that has security implications, or that has both. It is determined and issued by Microsoft as appropriate and when appropriate. GDRs are kept to a minimum and cannot be requested by a customer. Microsoft internally determines whether a...
Devart, formerly known as Core Lab) just released a new version of their ADO.NET providers, now with full support for .NET Framework 3.5 Service Pack 1 and Visual Studio 2008 Service Pack 1. From what I've read, they are the first to do so!
Devart is a software development company specializing in native connectivity solutions and development tools for the most popular databases, including Oracle, SQL Server, MySQL, PostgreSQL, InterBase, Firebird, and SQLite.
Check their announcement here.
There were a number of changes to the Entity Framework and the UI designer between Visual Studio 2008 SP1/ .NET Framework 3.5 Beta and the RTM that require updates to existing source code. These breaking changes are listed below, courtesy of the ADO.NET teamblog. These include the mitigation for adjusting to the new behavior, and a side by side comparison of Beta code and RTM code.
Provider Changes
1. The Function property of DbFunctionCommandTree is renamed to EdmFunction.
Affects:
- Provider writers
Mitigation:
- Replace ".Function" wtih ".EdmFunction"
SP1 Beta Code:
funcTree.Function
SP1 RTM Code:
funcTree.EdmFunction
2. DbExpression, DbAggregate and DbModificationClause no longer have...
During a programmer's lifetime, a top priority when developing new software is performance. New architecture is good, new technologies are good, but lets not be hasty: in this domain, "easier" and "new" sometimes leads to "slower". The CompiledQuery class let's you optimise your entity framework query expressions in an easy way, and that's what i'll be showing in this article.
I've recently come across a problem that I thought it would be simple to solve by using Entity Framework. I wanted to duplicate an object in order to make things easier for me, but I guess my assumption was incorrect. After some tests with reflection, google searches and a lot or brainstorming I've reached the conclusion that in Entity Framework there isn't a built-in or clear method that allows developers to clone objects and then persist the newly created object with some changes. In this article I'm presenting a solution to this.

The Entity Framework team is starting, from today, to develop the new Entity Framework v2.0. They will be posting design notes, pattern and architecture discussions every time there's something to be decided, so that everyone's opinion and insight can be taken into consideration and everyone can contribute to achieve the best Framework possible, considering every real world scenario.
Their blog already has its first post and there's more to come. So, in order to be a alongside the project development and even be "part of project", stay tuned with this blog.
I think this will be usefull for most people starting to develop over the Entities Framework. I'll explain how you can accomplish this by using the Skip and Top builder methods, and how it translates to Entity SQL and Transact SQL. You can read the full article here.
