DeploymentManager CSharp Sample Getting COM Execeptions

[mjfusa]

I'm getting the following errors with the DeploymentManager sample: Are these APIs, working properly, or is there an issue with the sample?

Scenario 1: GetStatus: Result Status: PackagelnstallRequired Result ExtendedError. System.Runtime.lnteropServices.COMException (Ox80070490): Element not found. (Ox80070490)

Scenario 2: Initialize: Result Status: PackagelnstallFailed Result ExtendedError. System.Runtime.lnteropServices.COMException (Ox800700E8): The pipe is being closed. (Ox800700E8) Initialize() failed to ensure the WindowsAppRuntime.
