如何从应用程序的证书库中删除证书？

Question

I've got Windows Store/Phone universal app that will have to store certificates. I have no trouble loading the certificates into the app's CertificateStore, and using them. But when it comes to deleting them I have trouble.

For example, the following code works great to find my certificate in the Windows Store environment:

async Task<Certificate> FindMyCert()
{
    var query = new CertificateQuery();
    query.FriendlyName = "mytestcert";
    var certificates = await CertificateStores.FindAllAsync(query);

    if (certificates.Count != 1)
    {
        return null;
    }
    return certificates[0];
}

Now, lets say I want to remove that certificate from the store. The only "Delete" I know about is on the CertificateStore object. So I need to fetch the certificate store and then do the delete:

var s = CertificateStores.GetStoreByName("MY");
if (s != null)
    s.Delete(c);
Assert.IsNull(await FindMyCert());

There is only one problem. If you look at the documentation for GetStoreName 1 , however, it says that the name of the certificate store can't be "MY".

The irony is this works sometimes and other times it doesn't work. I would guess there is an accepted way to do something like remove a cert from the store. But I have not been able to figure it out.

Many thanks in advance!

We were facing the same problem recently and opened a support ticket on that case. According to MS, this is not possible in Windows Phone 8.1, I'm sorry. It should be supported in Windows 10 though.
