In this post, I just want to help those of you out there that have upgraded from 2008 and need to bulk update all of your definitions. In this particular example, I will be updating the retention policies to remove the deletion of the label with the deletion of the build. This code is not complicated but does pull in a lot of different areas. So, I wanted to provide an example for everyone...

Here's the code:

using System;

using System.Collections.Generic;

using Microsoft.TeamFoundation.Build.Client;

using Microsoft.TeamFoundation.Client;

using Microsoft.TeamFoundation.Server;

 

namespace UpdateAllDefinitions

{

    class Program

    {

        static void Main(string[] args)

        {

            Uri serverUrl = new Uri("http://jpricket-test3:8080/tfs/defaultcollection");

            TfsTeamProjectCollection collection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(serverUrl);

            IBuildServer buildServer = collection.GetService<IBuildServer>();

            ICommonStructureService css = collection.GetService<ICommonStructureService>();

 

            // Get a query spec for each team project

            List<IBuildDefinitionSpec> specs = new List<IBuildDefinitionSpec>();

            foreach (ProjectInfo pi in css.ListProjects())

            {

                specs.Add(buildServer.CreateBuildDefinitionSpec(pi.Name));

            }

 

            // Query for all the definitions

            IBuildDefinitionQueryResult[] results = buildServer.QueryBuildDefinitions(specs.ToArray());

 

            // Update all the definition objects

            List<IBuildDefinition> definitionsToSave = new List<IBuildDefinition>();

            foreach (IBuildDefinitionQueryResult result in results)

            {

                if (result.Failures != null && result.Failures.Length > 0)

                {

                    // print out the errors

                    foreach (IFailure f in result.Failures)

                    {

                        Console.WriteLine(f.Code + ": " + f.Message);

                    }

                }

 

                // There still might be some definitions to modify in this result

                foreach (IBuildDefinition definition in result.Definitions)

                {

                    // Check for null, but we have already printed the error for this bad result above

                    if (definition != null)

                    {

                        ChangeRetentionPolicies(definition);

                        definitionsToSave.Add(definition);

                    }

                }

            }

 

            // Save all the definitions back to the server

            buildServer.SaveBuildDefinitions(definitionsToSave.ToArray());

        }

 

        private static void ChangeRetentionPolicies(IBuildDefinition definition)

        {

            // Update the retention policies to not delete labels

            foreach (IRetentionPolicy rp in definition.RetentionPolicyList)

            {

                rp.DeleteOptions = rp.DeleteOptions & ~DeleteOptions.Label;

            }

        }

    }

}

Hope this saves you some time!
