Viewing the output of Visual Studio's XSLT debugger

I'm using Visual Studio to debug a transform. If I am viewing the transform and select XML > Start XSLT Debugging, VS automatically opens the output file and as I step through the transform I can observe the output being written.

In my case however, because the transform is performed by an application that first sets some parameters, I am instead entering the XSLT debugger using the following code:

XslCompiledTransform xslTransform = new XslCompiledTransform(true); // enableDebug
XmlUrlResolver urlResolver = new XmlUrlResolver();
XsltSettings xsltSettings = new XsltSettings(true, true);
XsltArgumentList transformArgumentList = new XsltArgumentList();
// some arguments are set here
xslTransform.Load(transformFilePath, xsltSettings, urlResolver);             
using (XmlWriter writer = XmlWriter.Create(outputFilePath))
{
    xslTransform.Transform(inputFile, transformArgumentList, writer, urlResolver);
}

A breakpoint is set on the call to Transform. After starting the debugger, it breaks on Transform as expected. When I use F11 / Debug > Step Into, I enter the XSLT file and can step through it, but I cannot see its output.

Is there an option that I need to set in order to view the output as it is written, like in the former mode?

Not sure if this will help anyone, but here is Microsoft's "How to: Start Debugging XSLT" http://msdn.microsoft.com/en-us/library/ms255603%28v=vs.110%29.aspx

I'm not sure you can examine the stream in the debugger. Once XSLT debugging begins, you're no longer in the .NET world. My locals window only shows XSLT elements.

I made a feature request if you want to vote it up.

Unfortunately not that I am aware of.

I have to admit that I don't often need this, however you could replace writer with a MemoryStream backing stream (conditionally when debugging) which would at least allow you to see the xml output by examining the stream in the debugger.
