ASP.NET MVC and the Managed Extensibility Framework (MEF)

Tue, 21 Apr 2009 22:46:14 GMT

Microsoft's Managed Extensibility Framework (MEF) is a .NET library (released on CodePlex) that enables greater re-use of application components. You can do this by dynamically composing your application based on a set of classes and methods that can be combined at runtime. Think of it like building an appliation that can host plugins, which in turn can also be composed of different plugins. Since examples say a thousand times more than text, let's go ahead with a sample leveraging MEF in an ASP.NET MVC web application.

Interesting Observation of ON Clause on LEFT JOIN

Mon, 16 Mar 2009 21:16:19 GMT

Very simple explanation of : Although the placement of such predicates does not make a difference for INNER joins, they might cause a different result when OUTER joins are involved. This is because the predicates in the ON clause are applied to the table before the join, whereas the WHERE clause is semantically applied to the result of the join.

Interesting Observation - Effect of Clustered Index over Nonclustered

Tue, 24 Feb 2009 04:46:05 GMT

Query optimization is one art which is difficult to master. Just like any other art this requires creativity and imagination as well understanding of subject matter. Let us look at interesting observation which I came across. In our example we have one query which is not using any index. On the same table there is already nonclustered index created, which is also not being used. Now when we created clustered index on the same table, our query suddenly started to use nonclustered index which was so far it is not using. The interesting part of this is that query is using nonclustered index when clustered index is created on the same.

IRepository<T>: one size does not fit all

Mon, 19 Jan 2009 09:21:53 GMT

One pattern that has recently become popular in mainstream .NET is IRepository<T>. Originally documented in PoEAA, a repository is an adapter that can read and write objects from the database as if it were an in-memory collection like an array. This is called persistence ignorance (PI), and lets you forget about underlying database/ORM semantics.
