XBAP – content files

 

Test the difference between these and explain was the different “Build Action”’s do to these types of loading

// In project itself = "same directory on the server as my .xbap file"  
Uri uri = new Uri("pack://siteoforigin:,,,/StorageSCP.ass.xml");
// In project itself = compiled into main exe  
Uri uri2 = new Uri("pack://application:,,,/StorageSCP.ass.xml");
// In project itself = included as "loose content"  
Uri uri3 = new Uri("StorageSCP.ass.xml", UriKind.Relative);
StreamResourceInfo assXML = Application.GetRemoteStream(uri);
StreamResourceInfo assXML3 = Application.GetRemoteStream(uri3);
StreamResourceInfo assXML2 = Application.GetContentStream(uri2);

 

Also see what this does ?

Application.GetResourceStream(uri)

XBAP - SiteOfOrigin Files

 

I used this little snippet after a couple of hours hunting MSDN forums

StreamResourceInfo f = Application.GetRemoteStream(new Uri("pack://siteoforigin:,,,/"+fileSolutionPath));

//f.Stream //to your IO with this

Note: siteoforigin files are downloaded from the host on demand, so should be downloaded as needed.

Cool little beasty

I actually used this to copy some configuration files, DICOM Server Association files, to my Full Trusted XMAP home. I had made the Full Trust XMAP home (Environment.CurrentDirectory) a Temp folder i.e. System.IO.Path.Combine(System.IO.Path.GetTempPath(), "MyAppName") and needed to get the association list for a Storage SCP.

Thus

f.Stream.CopyTo((File.OpenWrite(Path.Combine(Environment.CurrentDirectory, fileSolutionPath))));

XBAP – Full Trust on the net

Full Trust XBAP Deployment

Starting in WPF 4, the ClickOnce elevation prompt is also enabled for XAML Browser Applications (XBAPs) in Intranet and Trusted Zones, making it easier to deploy full-trust XBAPs. For XBAPs that require security permissions greater than the minimum code access security (CAS) permission grantset of the Intranet and Trusted Zones, the user will be able to click 'Run' on the ClickOnce elevation prompt when they navigate to the XBAP to allow the XBAP to run with the requested permissions.

While developing DVD Burner Application, I wondered how many people are going to use the application then I came across XBAP and Full Trust. Although not a standard application of a Web App, it seems that XBAP is allowing me to get Full Trust via the internet. Very promising…

The key testability point for me was the “Intranet” AND “Trusted Zones”.

I could deploy the application on my laptop with IIS7.0 over the internet, and test it using my remote IP. This allowed me to test without being on a domain.

The only thing to do was to add my Remote IP to the “Trusted Zones” in IE, as long as your app is signed.
