Remove unused namespaces from Visual Studio

When we add any new class file, Visual Studio 2008 by default adds few namespaces depending on the project type. But, in real time – we will not be using one or all of the namespaces.

At the same time, most of us know only few namespace of the objects that we are going to use. So, it is a bit difficult to identify and remove the namespace. So, how can we make the code clean?

Fortunately, Visual Studio allows to Sort, Remove and Remove & Sort unused namespaces. The following pictures shows you how the class file looks like before and after removing the unused namespaces:

This is a very cool and useful feature

Behavior of dynamic type in C# 4.0

If you wish to get the type of any object dynamically and then invoke its methods are properties at run time, then C# 4.0 provides a new type called dynamic.

With this dynamic type, we can avoid compile time exceptions for method or property call. Compiler will just ignore dynamic types at the time of compilation. However, they will be evaluated at run time.

During the compile time, the variables of dynamic types are compiled into “object” type. So, type “dynamic” exists only at compile time, but not at run time.

This dynamic type can be used in following scenarios:

• A private field
• A public property
• Method return type
