Phil has a great post showing how we can have scripted views stored in database. Phil’s example avoids the classic approach using VirtualPathProvider and it can be run in medium trust.
As usual, Scott Hanselman has a great article on how to integrate ELMAH with ASP.NET MVC.
Jimmy Bogard has a great post about tips on development with MVC. I highly recommend you to read it!
Ayende started a few days ago an interesting talk about the repository pattern and its use. Between Greg and Ayende started a debate on each one’s blog. Greg says that the repository pattern offers a clean separation like a boundary and it easily facilitates the replacement of the persistence framework. He supports Ayende’s idea that Query objects should be used instead of named query methods as they are not SOLID as the repository’s interface is modified each and every time a method is added or changed. On the other hand, OO principles should be followed IN GENERAL but as the repository can be seen as a boundary, he acknowledges the fact that by having a repository with query named methods, the replacement of the persistence mechanism would be much easier as everything is described in the repository’s interface. With query objects we would have additional concerns with building dynamic criteria. Greg recommends command and query separation and the use of a separate layer for querying purposes only leaving the repositories concerned only with commands.
Ayende tries to clear things out and I think he did a great job. I think that both of them where speaking about things in different contexts each one being right in his own context.
The bottom line in my opinion is that one should not use the repository pattern unless a layer/tier boundary is needed. This is the case when for example one might think of changing the persistence mechanism. Otherwise, the persistence frameworks out there have become smart enough to be used directly.
Anne Epstein talks about multi tenant applications where multiple databases are used saying that Ayende’s opinion from a few months back was correct.

Muhammad wants to propose a new approach for eager loading in EF using a class similar to DataLoadOptions from LINQ to SQL.
In complement to my previous post on resources for learning the new features available in .NET 4.0, Daniel Moth just pointed out that Eric Eilebrecht has started a series of posts on ThreadPool improvements in CLR 4.0.
A few days ago, I have linked to the MSDeploy team’s announcement about the RC release of MSBuild. Today, the team has posted a new article about the changes in the release.
