I created a separate web service project using VS 2005. My first question is can I add more than 1 service (asmx) files and use them in single webservice project?

Hello, I have a web service that uses WCF. This web service has a single method that I want to be accessible from two different types of clients.

Following on from this question, would it be a wise idea to place a WCF service at the server side, between client and database to handle queries? The idea being that you take load of the network and reduce round trips to and from a database. I would use the Entity Framework to query the database in the service, and just send results t...
We have a few thousand Windows XP client machines on various customer sites that are all running some interactive software which is instrumented to collect anonymous usage data.

I'm looking for the best approach to share types (the actual classes, not proxies) between a WCF service and a client. To that end, I defined the classes in a separate assembly that both service and client reference. I selected "Reuse types in all referenced assemblies" when generating the service reference in the client, but Reference...
I have a project that I am experimenting with DI in. I am using Unity and things seem to work well for normal assemblies and the injections. I am trying to further break dependencies with WCF services. The WCF service that I want to inject is created at runtime currently without using DI and I don't use the VS .net generated proxies: ...

I could run a Windows Service hosted WCF service listening http://localhost:80/MyService while IIS was serving pages on http://localhost:80 and both works. But many places in the internet (like this and this) say that only a single process can listen each port simultaneoulsy. Are they wrong? ...
I'm using certificates to secure my communications between client and server (no code, just endpoint configuration). Certificates are currently stored in ACOS5 smart cards. Everything works very well except that every time when WCF creates a new channel to access the server, the ACOS5 driver asks user to enter “User PIN”. Unfortunately, ...

As also part of our IT's policy, for security reasons the web sites are not ...

Why does the ServiceBehavior attribute needs to be implemented on classes and not interfaces? Is there a way to make it global for all WCF services? Is there a way to specific the ServiceBehavior in the web.config file? I would like to have all of my WCF services to implement the InstanceContextMode == PerCall. Thank You, ...
