I have enabled my WCF service for Windows Authentication. How can I pass Credentials to Service from From Silverlight application.
For Credentials I can get User name and domain by code WebContext.Current.User.DisplayName. But how I will get client password through code.
serviceClient.Credentials = newSystem.Net.NetworkCredential("UserName", "Password", "Domian");

It should be done automatically if you have configured the client to use Windows authentication mode, please read following link:

What's likely happening is that SignalData is indirectly changing the subscribers dictionary under the hood during the loop and leading to that message. You can verify this by changing

foreach(Subscriber s in subscribers.Values)

foreach(Subscriber s in subscribers.Values.ToList())

If I'm right, the problem will disappear.

Calling subscribers.Values.ToList() copies the values of subscribers.Values to a separate list at the start of the foreach. Nothing else has access to this list (it doesn't even have a variable name!), so nothing can modify it inside the loop.

The best way for me has been forms authenication...using ASP.NET application services.

Basically you expose 3 *.svc files in your WCF service that handle authenication, roles, and profiles. There is no code behind because it's built into the .net assemblies. You will have to do some configuration in the .config (see link) to enable them.

Side Note on ASPNETDB.MDF

Normally all the user accounts and profiles will be in ASPNETDB.MDF which is located on a local file in the APP_Data folder but I find this clumsy especially with permissions so I kept it in my primary WCF database but you can choose another if you have the connection string. To initialize it I ran "C:\Windows\Microsoft.NET\Framework\v2.0.50727\a spnet_regsql -C *Data Source=localhost;Initial Catalog=MYDB;Persist Security Info=True;User ID=**;Password=****;" * -A all" to include the ASP.NET membership tables and sprocs into the db of my choice. If you do you this..ensure you override the default LocalSQLServer connectionstring or it won't find the db like this in web.config of your asp.net website

To actually add user accounts and roles

1) from Visual Studio 2) Click on your ASP.NET website 3) There should be a menu above called Website that shows up...select ASP.NET Configuration and your browser will start with the configuration website that will edit your config and update the configured database with accounts and roles

I hope this helps
