The Common Type System (CTS) is a component of the CLR and provides a common set of data types, each having a common set of behaviors. In Visual Basic, for example,

the String data type maps to the CTS System.String class. Therefore, if a JScript .NET client needs to communicate with a component implemented in VB .NET, the client doesn't have to do any additional work to exchange information because it's using a type common to both JScript .NET and VB .NET. The CTS eliminates many interoperability problems that exist outside .NET. .NET programming languages take advantage of the CTS by enabling developers to use their language's built-in data types the .NET compilers convert the native data types' into their equivalent CTS types at compile time. Developers can also use CTS types directly in their code if they wish. Table 1-2 describes each standard CTS data type.

.NET Class Library In an earlier section, "Consistent programming models across programming languages," the .NET Class Library was described as containing hundreds of classes that model the system and services it provides. To make the .NET Class Library easier to work with and understand, it's divided into namespaces. The root namespace of the .NET Class Library is called System, and it contains core classes and data types, such as Int32, Object, Array, and Console. Secondary namespaces reside within the System namespace. Examples of nested namespaces include the following: System.Diagnostics: Contains classes for working with the Event Log System.Data: Makes it easy to work with data from multiple data sources (System.Data.OleDb resides within this namespace and contains the ADO.NET classes) System.IO: Contains classes for working with files and data streams Figure 1-2 illustrates the relationship between some of the major namespaces in the .NET Class Library.

Figure 1-2: Organization of the .NET Class Library The benefits of using the .NET Class Library include a consistent set of services available to all .NET languages and simplified deployment, because the .NET Class Library is available on all implementations of the .NET Framework. Unifying components Until this point, this chapter has covered the low-level components of the .NET Framework. The unifying components, listed next, are the means by which you can access the services the .NET Framework provides: ASP.NET

Web Forms
Developers not familiar with Web development can spend a great deal of time, for example, figuring out how to validate the e-mail address on a form. You can validate the information on a form by using a client-side script or a server-side script. Deciding which kind of script to use is complicated by the fact that each approach has its benefits and drawbacks, some of which aren't apparent unless you've done substantial design work. If you validate the form on the client by using client-side JScript code, you need to take into consideration the browser that your users may use to access the form. Not all browsers expose exactly the same representation of the document to programmatic interfaces. If you validate the form on the server, you need to be aware of the load that users might place on the server. The server has to validate the data and send the result back to the client. Web Forms simplify Web development to the point that it becomes as easy as dragging and dropping controls onto a designer (the surface that you use to edit a page) to design interactive Web applications that span from client to server.
