Getting TFS to put the changeset in the assembly version

Question

I have got a Team Foundation Server Build running cleanly. It produces several assemblies and I would like the assemblies versions to have the last number to be the changset number. That is, if I commit with a changeset11667 for example the assembly version number should be "x.y.z.11667". I've checked the availible macros, but none is the changeset number.

I would still like to be able to build the solution file on my dev machine as normal, just using the checked in version number.

How would I go about getting this in place?

Answer 1

In the end a colleague of mine wrote the following MSBuild task that solved the problem.

public class GetNextBuildNumber : Task
{
    [Required]
    public string TfsCommand { get; set; }

    [Required]
    public string TfsArgument { get; set; }

    [Output]
    public int BuildNumber { get; set; }

    public override bool Execute()
    {
        BuildNumber = GetLatestVersionNumber();
        return true;
    }

    private int GetLatestVersionNumber()
    {
        var process = new RunProcess();
        var result = process.ExecuteCommand(TfsCommand, TfsArgument);

        return ParseResult(result);
    }

    private int ParseResult(string result)
    {
        const string changeset = "Changeset:";
        const string user = "User:";

        if (string.IsNullOrEmpty(result) || !result.Contains(changeset))
        {
            // Invalid result
            Log.LogWarning("Could not get latest build number. Reason: " + result);
            return 0;
        }

        var indexOfChangeset = result.IndexOf(changeset, StringComparison.InvariantCulture) + changeset.Length;
        var indexOfUser = result.IndexOf(user, StringComparison.InvariantCulture);
        var revision = result.Substring(indexOfChangeset, indexOfUser - indexOfChangeset).Trim();

        return Convert.ToInt32(revision);
    }

}
