What happened?
I am trying to run the .NET Core version of this migration tool as I want to host it in my cluster. However when I want to generate the configuration.json it throws an error when looking for an assembly that implements IMigrationClientConfig (see MigrationTools._EngineV1.Configuration.EngineConfigurationBuilder => GetMigrationConfigDefault()), as there are no non-interface implementations of this class in .NET Core. There seems to be only one implementation in this entire solution of this interface, namely TfsTeamProjectConfig. This class is contained in a full framework project (MigrationTools.Clients.AzureDevops.ObjectModel), and can not easily be implemented in .NET Core due to dependancies not being the same across the two .NET versions (namely Microsoft.TeamFoundation.WorkItemTracking.Client which has been depricated https://learn.microsoft.com/en-us/azure/devops/integrate/concepts/wit-client-om-deprecation?view=azure-devops).

MigrationTools.Clients.AzureDevops.ObjectModel seems to be quite an important project containing all the objects used to read the JSON config. I'm quite surprised that no similar class library is included for .NET Core, or am I missing something?

Debug in Visual Studio

The core version does not yet function. We are dependant upon the TFS Object Model which is full framework only.

Thank you very much for the expedient answer.
