How to host custom Web Service in Dynamic CRM 4.0

Question

Desired Outcome: Expose my own Web Service in Dynamic CRM 4.0 (IFD), and accessible by external application

e.g.

CRM Web Server URL: https://Org.CrmServer.com/

CRM Web Service URL: https://Org.CrmServer.com/MSCRMServices/2007/CrmService.asmx

My own Web Service URL: https://Org.CrmServer.com/MyServices/Dummy.asmx

Problem Encountered:

1. By accessing my Service URL in the browser, it redirects me to the sign in page. I entered a valid credential, and then it redirects me back to the Service Description page. So far so good

2. In my external application (C#), I've added Web Service Reference, and tried to call my Web Service by

   MyService.Dummy d = new MyService.Dummy();

   string s = d.HelloWorld();

3. The code above throws exception with error message (a HTML doc with "Object Moved" to CRM sign in page. (It's like what I see in the browser, redirecting to sign in page)

4. Modified code to pass in the credential but still doesn't work

   MyService.Dummy d = new MyService.Dummy();

   d.Credentials = new System.Net.NetworkCredential("username", "password");

   string s = d.HelloWorld();

Questions:

• Have I hosted my Web Service in the correct manner? If not, what's the correct way of doing it?

• How to I consume my Web Service without being redirected to sign in page?

Thanks for the help.

Answer 1

I've hosted web services inside the CRM Website. But to do this, I put them in the ISV folder. Therefore my service urls look something like

https://CrmServer.com/ISV/MyServices/Dummy.asmx

You could try doing it this way. I have assumed you are doing this on an IFD.
