Application Development with Microsoft .NET

The Microsoft .NET Framework is used to access and manage a variety data sources. ADO.NET includes data providers for connecting to a database and executing commands. Data can be transported data over the Internet using XML web services or across process boundaries using .NET remoting. ASP.NET runs web applications using MS IE: Internet Explorer. ASP.NET includes facilities for managing session state, security, and HTML generation using ASPX. Server-side web controls can be matched using custom tag ASP tags. Web controls encapsulate reusable user interface logic and facilitate web programming.

CLR: Common Language Runtime

The CLR runs managed MSIL code. The unmanaged code is pointer-based and runs outside the CLR. The Windows operating system does not automatically support a CLR. The .EXE runs because the CLR is first loaded by the shell executable CLR host, which then runs the user program in the loaded CLR. A CLR host is an application that sits between the CLR application and the operating system process. The host is responsible for loading the CLR into the operating system process and creating logical partitions in the OS process so that individual applications can reside in those partitions.

The .NET Framework provides these hosts:

Every CLR host comes with a piece of unmanaged code that must be run before it can load the CLR. In order to interact with the operating system for the first time, the CLR host must run some unmanaged pointer-based code. After this code is run, the CLR is loaded and the host creates a default partition for running managed code. A user’s application is not run in this default partition; instead, the CLR host creates partitions for running these end user programs. Traditional applications are separated by OS process boundaries, and this means that one application to share resources with another application you must make an out-of-process application.

The .NET application domain partitions applications within a single process in order that they do not directly share any resources, thereby preventing one application from affecting the execution of another application. Application domains are flexible and allow individual applications to be started and stopped without affecting the other applications running in the same CLR instance.

For organizations with substantial investments in mainframe infrastructure, there are a number of strategic decisions which have to be addressed when designing and developing a new .NET platform.

The .NET Framework class library is a collection of reusable types that tightly integrate with the common language runtime. The class library is object oriented, providing types from which managed code can derive functionality. The objective is to facilitate the utilization of the .NET Framework for reducing the time associated with learning new features.

The .NET Framework provides the capability to accomplish a range of common programming tasks such as string management, data collection, database connectivity, and file access.
