There are many way to debug WCF/Cloud service hosted in Azure and you can refer the below tutorial but I prefer to debug the service old and easy way by deploying the service in local IIS then publish to Azure.

https://docs.microsoft.com/en-us/azure/vs-azure-tools-debug-cloud-services-virtual-machines

https://docs.microsoft.com/en-us/azure/vs-azure-tools-debugging-cloud-services-overview

In Part 1, I explain how to create and deploy WCF Restful service in Azure.

https://arvindcsit.blog/crm-and-azure-integration/

I will use the same existing code and will add another POST method to explain debugging.

I am going to create one POST method which takes User Name and Password as request body and return predefined token.

So I added below code in Part 1 source code.

Contract: ICRMService.cs

Under ServiceContract

[OperationContract]
[WebInvoke(Method = “POST”,
UriTemplate = “/getauth”,
ResponseFormat = WebMessageFormat.Json)]
CRMTokenResponse GetCRMToken(CRMTokenRequest tokenReqeust);

DataContract
[DataContract]
public class CRMTokenResponse
{
public CRMTokenResponse()
{
this.Token = “”;
this.Error = “”;
}
[DataMember(IsRequired = false)]
public string Token { get; set; }
[DataMember(IsRequired = false)]
public string Error { get; set; }
}
[DataContract]
public class CRMTokenRequest
{
[DataMember]
public string Username { get; set; }
[DataMember]
public string Password { get; set; }
}
CRMService.svc.cs
public CRMTokenResponse GetCRMToken(CRMTokenRequest tokenRequest)
{
CRMTokenResponse resp = new CRMTokenResponse();
if (tokenRequest != null)
{
string userName = WebConfigurationManager.AppSettings[“CRM.Username”];
string password = WebConfigurationManager.AppSettings[“CRM.Password”];
string tokenId = WebConfigurationManager.AppSettings[“CRM.Token”];
if (tokenRequest.Username == null || tokenRequest.Password == null)
{
resp.Error = “Enter UserName and Password”;
return resp;
}
if (tokenRequest.Username.Equals(userName) && tokenRequest.Password.Equals(password))
{
resp.Token = tokenId;
}
else
{
resp.Error = “Invalid Username & Password”;
}
}
else
{
resp.Error = “Request is Null”;
}
return resp;
} 

Web.config

Add these three lines under <appSettings></appSettings> tag.
<add key=”CRM.Username” value=”Arvind” />
<add key=”CRM.Password” value=”Singh” />
<add key=”CRM.Token” value=”8178746c24b9f5544d259f2a38d7c1a785bc70a2″ />

We are done with code changes, make sure you build the project in Debug mode and deploy in local IIS.

Browse the service and make sure the service is running without any error. I will use PostMan to hit and debug the service.

Set the breakpoint and attached to W3WP process. Select the Content Type and Request Body as below.

Then Click “Send” and cursor will stop at breakpoint as shown below.

you can see the token value while debugging as below

Finally, you get output in output window of PostMan as below.

Similarly, you can debug it for GET method. Once your service is working fine, you can publish your service to Azure using steps mentioned in PART 1 (https://arvindcsit.blog/crm-and-azure-integration/)

Hope this helps you.
