In reference of this question
I've read this blog entry, but I can't see any functionality to set metadata template in the sdk.
Related to work with custom template parameters I only know search functinality with BoxMetadataFilterRequest object in the SearchAsync
method.
There is any news about this functionality to set or recover with the sdk (https://github.com/box/box-windows-sdk-v2)? Or only with Restsharp (or similar) messages I can use this?
Currently this functionality is not supported through the Windows SDK.
As you mentioned, you would have to call the metadata endpoints directly using a REST client like Restsharp.
Here is the documentation for the relevant Box Content API endpoints:
