VisualizerDevelopmentHost Class 

Namespace: Microsoft.VisualStudio.DebuggerVisualizers
Assembly: Microsoft.VisualStudio.DebuggerVisualizers (in microsoft.visualstudio.debuggervisualizers.dll)

You can use this class to create a harness for testing and debugging a debugger visualizer. Visualizers are small custom applications called from the Visual Studio debugger to display data objects in a manner appropriate to their data type. The VisualizerDevelopmentHost class enables you to run a visualizer for testing and debugging purposes without installing the visualizer into Visual Studio. Using the harness makes debugging a visualizer much easier.

The following example code creates a visualizer development host and calls the host to show the visualizer. MyDataObject is the data object you want to show in the visualizer. MyVisualizer is the visualizer itself.

public static void TestShowVisualizer(object MyDataObject)
   VisualizerDevelopmentHost visualizerHost = new VisualizerDevelopmentHost (MyDataObject, typeof(MyVisualizer);

The calling code looks as follows:

String myString = "Hello, World!";  // Create an object to visualize
Visualizer1.TestShowVisualizer(myString);  // Call the host to visualize it
