How to add a Web service reference in a C # class library

This article is not a profound article, but only a small part of VS2008 application, but a small part of you will not necessarily, or you try:

I for the distributed development application is not much, this time there is a project to apply the Web service, my development environment is vs2008, the reason why do not choose the current hot WCF, I have the following reasons:

1: The team responsible for the development of Web service for VS2008 application is not much, not to expect coveted WCF.

2: The project development time is limited, you are not allowed to take the project to do experiments.

3: The project changes little, the Web service is enough to deal with demand.

Since our project is directly upgraded from 1.1 to 3.5, upgrade, the Web project directly into the class library, so no matter how much changes in the environment, as long as the compatibility of low-level version, all the original files are available, for example, 1.1 to create a Web page, there will be a RESX resource file, But the page created in 3.5 is Designer.cs, if you upgrade later, as long as the relevant new file types created, and then added to the class library, so you can enjoy the advanced version of the function, said the more ambiguous, do not know whether you understand.

Now to do is to reference the Web service in such a class library, intuitively think, just add a reference does not it? Is that really the case?

First: Right-click on the Web project, as shown in Figure I.
