'System.ServiceModel.FaultException`1' occurred in mscorlib.dll Error C#

Good Morning.

As a part of my ongoing project for an in house integration, I need to push some data into our MS Dynamic CRM erp from a custom application.  My code was working fine until yesterday, when I started getting the error :

A first chance exception of type 'System.ServiceModel.FaultException`1' occurred in mscorlib.dll

I am calling a webservice from a C# windows client.

My code is as below

private void button1_Click(object sender, EventArgs e)
            testAX.TelephoneRevenueClient tel = new testAX.TelephoneRevenueClient();
            testAX.Alle_TelephoneRevenueData rev = new testAX.Alle_TelephoneRevenueData();

            tel.ClientCredentials.Windows.ClientCredential.Domain = "dddd";
            tel.ClientCredentials.Windows.ClientCredential.UserName = "testuser";
            tel.ClientCredentials.Windows.ClientCredential.Password = "mtestpassword";

            tel.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

            DateTime dt1 = new DateTime(2015, 05, 01);
            DateTime dt2 = new DateTime(2015, 05, 28);

            rev.parmAcctNum = "045013771";
            rev.parmCustAccount = "500725";
            rev.parmDepartment = "015";
            rev.parmLOB = "010";
            rev.parmPeriod = "201405";

            //rev.parmRevFixed = Convert.ToDecimal(pfRev);
            //rev.parmRevUsage = Convert.ToDecimal(puRev);

            rev.parmSDate = dt1;
            rev.parmEDate = dt2;

            tel.insertRevenue(new testAX.CallContext(), rev);

In Visual Studios, do you have debugging enabled for exception assistant and "Just My Code (Managed Only)"?

In Visual Studios, go to Tools -> Options (of the Integrated Development Environment):

Enable the exception assistant,
Enable Just My Code (Managed Only)

If the above are unchecked, I don't know what the problem is.  But based on your description (with the problem rearing its head upon a client connecting), I bet the above are checked.  You could try unchecking them and see if the problem goes away.

Disabling the error option in the Visual Studio Editor Tools->Option menu of IDE

- Uncheck  Visual Studio Editor Tools -> Option -> Debugging -> General -> Enable the exception assistant.
- Uncheck  Visual Studio Editor Tools -> Option -> Debugging -> General -> Enable just my code.

After that you will get the actual error which was throw by web service instead of FaultException.

Hi Phil.

These were already checked. I tried unchecking. However still the same issue.

find the <bindings> section in webservice configuration and write it here with obfuscated values.

Hi Fareed.

                <binding name="NetTcpBinding_TelephoneRevenue" />
            <endpoint address="net.tcp://test12314:8202/DynamicsAx/Services/TeleRevenue"
                binding="netTcpBinding" bindingConfiguration="NetTcpBinding_TelephoneRevenue"

Write the code here you used to register the TCP Channel and client channel. I need to check the channel registeration.

The issue was resolved by re-compiling the webservice in MS Dynamics AX.
