COM + integration scheme of existing programs and WCF programs.

WCF is the next generation of Microsoft's support and implementation of Web and distributed technologies. How can I integrate with existing COM + programs using WCF? We have considered the following centralized methods.

1. It is still a common. NET program to call COM + existing programs. For. NET, directly reference the ServicedComponent call. For an unmanaged program, you want to call a common COM.

2. When Queud Component is used, the client accesses the same Queue as the client.

3. Expose the COM + program as the Remoting Service. The client is called using remoting CAO (client activation method.

4. Use the COM + integtration provided by WCF. Expose the COM + program as a standard HttpBinding-based Web service. Interface that can be displayed. In this way, all the WCF clients can call the API. This scheme can be based on http or net. pipe. The service program can host in com + or web program.

For the fourth method. WCF used a tool named comsvcconfig.exe, installed in C: \ WINDOWS \ Microsoft. NET \ Framework \ v3.0 \ Windows Communication Foundation
For existing COM + programs, it can help you generate a WCF Service configuration and install it.
