Some Important Features of Dot Net
1. Interoperability support (Interop)Migrating to . NET from existing languages and platforms
has been made much easier; Especially if that environment is COM or Java. COM, Interop is
built into the framework, and C# will be very familiar for those developing in Java currently. In
fact, Microsoft has a migration utility to automatically migrate existing Java source code into
2. Common language runtime (CLR)
This is the engine that is shared among all languages supported in . NET, including C#, VB.
NET, Managed C++, J#, and others to come. With the help of the CLR, the developer can write
base classes in VB. NET, child classes in C#, and aggregate this tree from Managed C++ (this
is just one example). You choose the language during implementation.
3. Base class library (BCL)
What makes Java so appealing besides the managed environment and cross-platform support is
its class library. The . NET framework takes the class library concept a step further by
supporting it across any language and extensible for future platform variances. Now BCLsupported
features such as remoting, string manipulation, exception handling, and collection
management construct is the same from any language conforming to the CLI.
4. Common type system (CTS)
This addresses the supported data types within the framework and how they are represented in
metadata format. Each supported . NET language need only support a subset of the total data
type set. Typically, it will be those types used most frequently (e. g. , integer, short, long, string,
char, boolean, object, interface, struct, etc. )
5. Simplified deployment
Say goodbye to DLL hell and the nightmare of Windows registration. Applications can now be
deployed by a simple XCOPY of the assemblies, ASP. net files, and configuration files.
6. Full Web service and SOAP support
Complexities are optionally hidden for building Web service providers and consumers in . NET.
Details of the syntax and protocol surrounding XML Web services can be fully customized if
needed, however. It is truly the best of both worlds.
7. XML at the core
Serialization, streaming, parsing, transforming, and schema support are only some of the
“baked-in” XML features of the . NET runtime.
8. Object-oriented ASP. NET
Use script for your clients, not your server-based code! Leverage your existing OO framework
from ASP. NET and enjoy improved Web application performance due to compiled server
