  <p>I'm using TFS 2017 update 1 on premises (I'll upgrade to Dev Ops Server 2019 update 1 asap) in a very large project with hundreds of users and after two years we collected more than 10000 work items in a single Team Project (10661 to be precise). I hope that I will able to add new work item in the future without limits in the same Team Project (I think it's reasonable to have a limit like 500000 or 1 million of work items but no with only 10000 work items). I'm afraid that I'll see an error message like "TFSXXXX: max number of work items reached".</p>
