Hi @annelo-msft
Any progress on this?

Hi @DBojsen - yes, we are making progress on it, although I don't have an answer for you just yet on what the outcome will be. One thing that is different from when we initially corresponded about this is that I am now confident that we will be able to expose serialization capabilities publicly. We are working on the details in a way we can solve the problem holistically for the SDK, which is why there's a greater investment of time needed. Thanks!

Hi @rquackenbush

I solved my issue for the time being by using reflection. Perhaps that will work for you also?!

@annelo-msft I am assuming this issue is getting resolved as part of the model reader writer support.

The goal of this issue was to track the various model serialization issues in one place so that when we provided a solution they would all be addressed with one set of types. I assume @m-nash was aware of the design requirements and has been using them in the serialization work.

I believe this has been addressed with the new IPersistableModel<T> interfaces in System.ClientModel v1.0.0
