This is a modification of the WCF Binary Message Inspector. It provides two notable enhancements:

1. Uses a collapsible tree view instead of a textarea to display the decoded WCF binary message.
2. Allows editing and reissuing of captured WCF binary messages (thanks to HofmaDresu)

Copy the file BinaryMessageFiddlerExtension/bin/Release/BinaryMessageFiddlerExtension.dll (direct download) into C:\Program Files\Fiddler2\Inspectors and restart Fiddler.

Copy the file BinaryMessageFiddlerExtension/bin/Release/BinaryMessageFiddlerExtension_Fiddler4.dll (direct download) into C:\Program Files\Fiddler2\Inspectors and restart Fiddler.

The tree view provides the following shortcuts:

• Ctrl+c — Copy current node XML
• Ctrl+Shift+c — Copy tree XML
• Alt+→ — Expand node and all child nodes
• Alt+← — Collapse node and all child nodes
• Middle-click — Toggle expand/collapse of node and all child nodes

1. Capture a WCF binary message
2. In the sessions list, right click on the message and choose "Unlock for editing"
3. Edit the request
4. Reissue the request using the toolbar or the session list context menu

The project is a Visual Studio 2010 project, and requires a reference to your Fiddler.exe file in order to compile.
