Hi Team,
We are upgrading from version 8.1.5 to 9.0 , we noticed that post upgrade our custom api has been missing.
As api designer is decommissioned in version 9.0 we are aware that we need to convert our api designer code in to custom dll.
when we are migrating the code to custom dll we are only only able to see the custom methods if we attach to existing apps like QER.CompositionApi.Portal.PortalApiProject or QBM.CompositionApi.AdminApi.AdminApiProject
but we implemented these methods under custom project in version 8.1.5 , what is procedure to create a custom API project in version 9.
