Passing URL parameters to a WPF browser application
A colleague asked:

So, can you pass in URL parameters to a WPF browser application (.XBAP)? Sure you can. However, only if the XBAP is deployed over HTTP. You cannot launch an app from a UNC share and expect to pass it HTTP request parameters.
Here's how: You need to specify
This functionality will not be available when you run the app within Visual Studio (i.e. hitting F5 or Ctrl-F5) because WPF applications launched from within Visual Studio are not ClickOnce-deployed.

I have a task on my plate to change the StartURI for our app based on query parameters to the xbap app. Is that possible?
We have one app (which combines Foo and Bar), but when users launch "myapp.xbap?view=Bar", I’d like to show a different initial UI.

Here's how: You need to specify
<TrustUrlParameters>true</TrustUrlParameters>
in the project file and use System.Deployment.Application.ApplicationDeployment.CurrentDeployment.ActivationUri property to get to the URL and pull the request parameters from it.

Unfortunately there isn't support in loose XAML to get to the activation URI (and by extension to the request parameters). We're looking at solving this in a future version.

Do you have to publish the site to get the URI?
Can you do it by opening C:\project.xbap?

I am trying to pass the binary string which represents a .png file to an xbap. The length of this file is longer than is usually allowed by a query string. So is there another way to pass parameters to an xbap?
Thanks.
