Resolved.

    OutputWriter::WriteLine(TEXT("Calling InitializeForBackup")); 
    CHECK_HRESULT(pBackupComponents->InitializeForBackup()); 

    //Try to set the context so that we could see it as a persistent snapshot for Exposing it.
    CHECK_HRESULT(pBackupComponents->SetContext(VSS_CTX_APP_ROLLBACK | VSS_CTX_BACKUP));

. . OutputWriter::WriteLine(TEXT("Exposing Snapshot")); 

        PWSTR wszExposed;

        CHECK_HRESULT(pBackupComponents->ExposeSnapshot( snapshotId, NULL, VSS_VOLSNAP_ATTR_EXPOSED_LOCALLY, L"N:", &wszExposed));

Glad you resolved it, but this isn't technically a hobocopy issue. Happy to help with stuff like this over on the mailing list, though.
