I have a number of classes that wrap Windows.Devices.Enumeration.Pnp.PnpObject to provide easy accessors for properties I expect to be included in the Properties member. In the transition from .net framework 4.6.1 to .net 5, I started hitting an access violation: #635
As a work around to that issue, I started making a managed copy of the properties as part of the constructor for my wrapper classes. This seemed to work fine until recently. I don't have multiple test environments to verify but it seems as though updating Windows has caused this because it repros with the old nuget version I was using 1.1.4, and the latest 1.2.6. What happens is that named Pnp properties like "System.Devices.ContainerId" sometimes return an object of the wrong type.
I have attached a simple repro that executes the same code in a .net framework project referencing the winmd and a .net 5 project using the latest CSWinRT nuget package to illustrate the difference.
