Expected Behavior

NOTE: This issue appears inconsistently. With the same Terraform configuration and the same commands, this configuration will sometimes apply and destroy as expected. Other-times not.

Applying this plan should consistently create a project under my organization in Azure Devops and consistently be tracked in the Terraform state.

Actual Behavior

NOTE: This issue appears inconsistently. With the same Terraform configuration and the same commands, this configuration will sometimes apply and destroy as expected. Other-times not.

1. Applying this plan led to Terraform throwing the error:
   Error: Provider produced inconsistent result after apply

2. The project is created and viewable in the UI

3. When running apply a second time Terraform throws this error indicating it is not tracking the resource state:
   Error: Error creating project: TF200019: The following project already exists on the Azure DevOps Server: TEST_PROJECT_00. You cannot create a new project with the same name as an existing project. Provide a different name.

4. terraform destroy (as expected) does not have any trackable resources to destroy

Steps to Reproduce

1. terraform apply
2. terraform apply
3. terraform destroy

@bb-josh Thanks for the feedback. I can reproduce this error by manually change the service response. The project has been created but when provider try get the project, service response indicate that this project was not found. In this scenario, the ADO provider will set resource ID to empty string to notify Terraform that this resource should be deleted from the state file. One way to fix this issue is enhance the get project logic, a retry logic should be helpful here.
