Windows Services - Best practice question???

I also wanted to add that the reason I'm asking is because I'm rewriting services that were written in C++. So I wanted to know why in .NET the traditional way of creating services changed? In what scenario would you want to go the route of having multiple services in one process? Unfortunately there isn't much written on this subject. So any help would be highly appreciated. Thanks In Advance...

It is a long running executable. If you create a new windows services project and use the template. It states the following; More than one user Service may run within the same process. To add another service to this process, change the following line to create a second service object. For example, ServicesToRun = new System.ServiceProcess.ServiceBase[] {new Service1(), new MySecondUserService()}; So my questions are: 1. When would you want to do this? 2. Why would you do this versus the more traditional way which is one service to one process? 3. What are the benefits of having multiple services in one process? 4. If in the above example one service crashes will it crash the other service or will it hinder the other service's performance? 5. Do you know of any good books for Windows Services? The only one I could find was written for VB and I'm using C#.

Hi What do you understand under a windows service? I think, also in .net, there is one process per windows service. Maybe i don't understand you correctly... Simon
