Getting error message ACCESS_DENIED when opening device handle through Metro app

Question

Metro app is throwing error message ACCESS_DENIED when trying to get handle to the driver.

Steps followed:

1. Install device driver successfully
2. Generate Metadata
3. Copy experience id from Metadata to the StoreManifest of the Metro app

Right now I have installed WDF driver with settings as mentioned in link (msdn.microsoft.com/en-us/library/windows/desktop/hh404264%28v=vs.85%29.aspx) enabled in both INF file and driver code

But still Metro app throwing error message 'Access_Denied'. I have following information:

1) Metadata file is not getting copied from WindowsMetadataStore to WindowsMetadataCache folder. Is this issue ?

2) Tried manually copying Metadata file to MetadataCache folder but still getting error message 'Access_Denied’.

Thanks.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
