Pass Authentication to Async Web Service Method Call

[Bob]

I have a web service that has been running nicely for four years now. I need
to update the Web Application that consumes it to use Silverlight. I don't
much want to write the web service. The service web methods pass credentials
in the SOAP header.

So the old app goes something like this:-

MyService srv = new MyService();
MyService.MyCredentials cred = new MyService.MyCredentials();
cred.UserName="foo";
Cred.Password = "bar";
MyService.MyCredentialsValue = cred;
string[] results = MyService.GetMyData();

Now we are in a Silverlight Page and I have to use the async methods
something like this:-

MyService srv = new MyService();
srv.GetMyDataCompleted+= new GetMyDataCompleteHandler...;

There is no MyService.MyCredentialsValue.

So is there a way to pass the header credential info to the method?

There was no way for you to know it (except maybe by browsing through
some of the previous questions before posting yours - always a
recommended practice), but this is a classic (COM-based) asp newsgroup.
ASP.Net is a different technology from classic ASP. While you may be
lucky enough to find a dotnet-savvy person here who can answer your
question, you can eliminate the luck factor by posting your question to
a newsgroup where the dotnet-savvy people hang out. I suggest

microsoft.public.dotnet.framework.aspnet.

There are also forums at www.asp.net where you can find a lot of people
to help you.
