Certified metro App not work with device Metadata RRS feed

  • Question

  • I first build a Metrop DeviceApp and a device metadata package (I use FX2 device access sample). They work well. I then do PROJECT->Store->Create App Packages to create a developer certified App package. After this, the App will get access denied error trying to connect to device driver.

    Even though I tried to use VS12 to rebuild App and deploy it, it will get "access denied" error.

    To make it work again, I modified .CSPROJ file to remove line 


    The question is: how to make a certified metro App to work with device metadata package?

  • My case is different. Metadata works with device access. It has problem with "Access Denied" only if I make my Metro App as developer certified Metro App. These are steps from Access OK --> Access Denied --> Access OK.

    1. Using Metadata authorization Wizard to create and submit metadata package.

    2. Build a Metro App (use FX2 device access sample) and deploy the App. Access OK.

    3. PROJECT->Store->Create App Packages to create a developer certified App package. Access Denied. Even though I rebuild and deploy it from VS12, access is still denied.

    4. Modify .CSPROJ file to remove line <PackageCertificateFile>CustomerDeviceAccess_TemporaryKey.pfx</PackageCertificateFile> (line is added by VS12 at step 3), rebuild and deploy through VS12. Access OK.

    The issue here is "a certified metro App does not work with device metadata package".

    I tried the steps mentioned in URL you listed. Issue is same. A strange senario is that I removed all cached files from ..\dmrcache\multiproc, and the metadat package from ..\DeviceMetadataStore\en-US,  reboot after taht, the device access is still working.
