runtime error running metro store app with SmbiosInformation.SerialNumber

Question

I tried to get serial number by calling an API, like this: "string serialNum = Windows.System.Profile.SystemManufacturers.SerialNumber ",  it throws an exception saying "Access is denied".

I am using VS 2013RC, running this app on Windows 8.1 Preview. Can anyone give me help? Thanks.

Answer 1

Hi lisarom,

The SerialNumber property securely retrieves the serial number from the SMBIOS for the system. This property is partial trust, so in a Windows Store app, you must specify the app in the system's metadata before retrieving any properties.

the words comes from: http://msdn.microsoft.com/en-us/library/windows/apps/windows.system.profile.systemmanufacturers.smbiosinformation.serialnumber.aspx

If you do not specify this app in your system metadata you could not get any properties and an "Access Denied" will be thrown.

Thank you for your quick reply.

I've still got the same error when I tried to specify the app for SMBIOS in metadata. Could you please check the following steps, tell me what are the correct steps.

1.run Device Metadata Authoring Wizard->Package Type(Internal device) ->Device Categories(Notebook)->Locales(en)->Device Info(model name:XX, Manufacturer:XX)->Hardware Info(import from this computer)->App Info(store Package name:xxx, Publisher name:xxx)->check "Copy the metadata package to the metadata store on the local computer"

2. After that, I got three files, which are Device manifest file and Device Metadata file and StoreManifest.xml 

3. add the StoreManifest.xml to the application.

Thanks.

Hi lisarom,

Read this for more information, the steps are detailly described: http://msdn.microsoft.com/en-us/library/windows/hardware/hh454247(v=vs.85).aspx.

I do not have experience on using Device Metadata Authoring Wizard, but I think the document I provide you can help you solve your question. Hope it works.

Hi Eric,

Sorry for the delay.

No. We just want to provide some unit info such as serial number, model number etc to customers.

This is unfortunately not supported for this scenario.

Dear Eric,

  let me jump in here; we're facing the same issue - and are working on behalf of an OEM who asked us to develop a metro app that can be aware of the serial number of the notebook to display info on the warranty, etc.

Can you help? What should we do?

Best,
