the assembly is in the GAC. If you are using the generated metadata for unmanaged visual Basic 6.0 or Visual C + + components, you can remove the generated assembly from the GAC if no reference is passed.
This version of the. NET framework requires special attention: if an assembly is loaded and the assembly file is accessed using System.Reflection, the file is locked in memory until the process is finished. Reflection is used when dynamically gener
The power of WEB services is interoperability. Because of the industry's collaboration in Web Services technology (SOAP, WSDL, UDDI), more specifically because of the Web Service Interoperability Organization (Web
, REST has become the most important Web service design model in recent years. In fact, REST has a very large impact on the Web, and because of its ease of use, it has generally replaced SOAP and WSDL-based interface designs.The concept of REST was 2000 by Roy Fielding at the University of California at Irvine during the academic paper "Architectural Styles and the Design of network-based software Architect

unmanaged COM + components cannot be published correctly using COM + WEB services. One of the purposes of COM + WEB services is to minimize the time and effort required to make such an assessment. By simply publishing an unmanaged COM + component as a COM + Web service, the
JSR-311, which has become an integral part of java™6.This article argues that the specific implementation of the most pure form of restful Web service that is attracting so much attention today should follow four basic design principles:
Explicitly use the HTTP method.
No status.
The URI that exposes the directory structure.
Transfer XML, JavaScript Object Notation (JSON), or both.

The student identity authentication module consists of one Web Service:

The business layer is usually the business logic
The data layer is designed to encapsulate data access and manipulation to provide an abstract data model at the business level.
Web services typically have remote procedure call (RPC) and restful (HTTP) classes, and now the dominant Web service is
managed or unmanaged wrappers that provide a compatible interface that can be published as a WEB service. In most cases, writing such a wrapper is much less work than rewriting the entire component. This minimizes the development and testing effort required to apply existing applications as XML Web Services.

DWS also supports an integrated test environment in which you can deploy and test the generated services with just a few clicks of the mouse.

For simplicity, the examples above all use VBScript to access the WEB service. The SOAP WSDL moniker can actually be written using Visual c+, Visual Basic 6.0, Visual Basic. NET, or C #. For example, Visual Basic. NET can also use compiled managed code to access the same object, as shown in the following example:

It is sufficient to provide general IIS services. However, you must follow the vs2005 or vs2008 computer to use Asp.net development server to provide IIS server.
But don't worry. Just copy a few key files and run Asp.net development server on a computer without a development environment.
Let's take a look at how to start the service of Asp.net development server.
