You work in an international company which is named TXTWIN. And you’re in charge of the company network and use Microsoft BizTalk Server 2006 R2.
An orchestration and a custom Microsoft.NET Framework assembly are created by you. An error is thrown when the orchestration calls a method named Identify in the custom .NET assembly. When the method is called from the orchestration, you have to step through the Identify methods code in the .NET assembly. So what should you do?

A.
You should find an instance of the orchestration, and open the Routing Failure Report by using the BizTalk administration console.
And then step through the orchestration and into the Identify method of the custom .NET assembly.

B.
You should find an instance of the orchestration, and open the Orchestration Debugger by using Health and Activity Tracking (HAT).
Set breakpoints as needed.
Run an instance of the orchestration, and step through the Identify method.

C.
You should use Microsoft Visual Studio 2005 to open the custom .NET assembly project, and on the Identify method, set a breakpoint.
On the Debug menu, click Attach to Process.
From the list of available processes, select the BTNTSvc.exe process.
Run an instance of the orchestration.

D.
You should use Microsoft Visual Studio 2005 to open the orchestration project, and on the Identify method, set a breakpoint.
On the Debug menu, click Attach to Process.
From the list of available processes, select the BTNTSvc.exe process.
Run an instance of the orchestration.
