In order to interact with the Azure Devops (VSTS or TFS), you can use several approaches:
- Develop your own library through HttpClient that is not complicated, and the example can be found here.
- Use existing nugget packages: Microsoft.TeamFoundationServer.Client.
Example of the package installation and the result displayed below.

Connection through VssConnection may be reached with several methods:
- Connect to the Azure DevOps Server (TFS) using the current user:
VssConnection connection = new VssConnection(new Uri(ServiceURL), new VssCredentials());
- Connect to the Azure DevOps Server (TFS) using the custom user and password:
VssConnection connection = new VssConnection(new Uri(ServiceURL), new WindowsCredential(new NetworkCredential(User, Password)));
- Connect to the Azure DevOps using Personal Access Token:
VssConnection connection = new VssConnection(new Uri(ServiceURL), new VssBasicCredential(string.Empty, PAT));
For further interaction, you have to create clients:
WitClient = Connection.GetClient<WorkItemTrackingHttpClient>();
BuildClient = Connection.GetClient<BuildHttpClient>();
ProjectClient = Connection.GetClient<ProjectHttpClient>();
GitClient = Connection.GetClient<GitHttpClient>();
TfvsClient = Connection.GetClient<TfvcHttpClient>();
TestManagementClient = Connection.GetClient<TestManagementHttpClient>();
The list of the main clients:
- WorkItemTrackingHttpClient – a client to work with work items.
- GitClient – a client to work with the Git source code repository.
- TfvsClient – a client to work with the TFVC source code repository.
- TestManagementClient – a client to work with test plans, tests, etc.
- BuildClient – a client to work with builds and build definitions.
- ProjectClient – a client to work with team projects.
