Hi there!
It is by design and we'll be happy to explain why and also how to work around.
First off, you absolutely can create .url file just like with Cassini. Application redirector at port 7756 is still there.
Now, regarding the issue at hand. Your physical location parameter, "path", should be pointing to the folder with the root web.config file. For example, if your root web.config is in the /src folder, you should change path parameter value to "C:\Program Files\Software Productivity Research LLC\KnowledgePLAN\Src". If your web.config is in the "C:\Program Files\Software Productivity Research LLC\KnowledgePLAN", then the you've done everything correctly, except setting default document.
Default document is not meant to be used as default redirect to another folder document. Default document tells server which document in the folder should be served when URL ends with folder names, and therefore it should be always pointing to a document in the root folder. The fact we have not enforced that and let you register the application with ".\src\Default.aspx" is our fault, and it's now a bug to be fixed.
If you would like your application to start with URL pointing to ~/src/, then your
default document in the site root should be redirecting to it. We also will add an ability to use any document in any folder to our redirector web application.
We are sure that if you pointed your browser to the /src/, the the login page would have an address with "?ReturnURL=/src/Default.aspx" query string. Currently it is probably "?ReturnURL=/Default.aspx" when you request application root folder. So the bottom line, you might need to make your default application document redirect to the ~/src/.
P.S. In UWS, unlike IIS, default document is applicable to all folders in the application. However, if you leave default document unspecified, UWS will look for any of the usual default document names, including Default.aspx, index.htm, etc.
