You are developing an XBAP application for your company intranet. During several development iterations, you manually copy the working executable, application, and deployment manifest files to the test Web server. You create an HTML file that has a hyperlink to the deployment manifest that you use for testing. During the next iteration, you enhance the XBAP application by making changes to the application.
When you use the hyperlink to the deployment manifest to test the deployment, you do not see the changes.
You need to ensure that the changes you make are visible when you test the deployment from your machine.
