MSBuild TFS Build Number

I have been using SVN for a little while now. recently on a project I am using TFS. With the builds I like to append/update the build version number on the project output. I do this on the masterpage so that it is clearly visible on the application. Since the application could be running on multiple machines, it is handy information on which verison are running.

I achive this in SVN world as:

  <!-- Import of the MSBuildCommunityTask targets -->
    <Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" />
    <!-- to AssemblyInfo to include svn revision number -->
    <Target Name="BeforeBuild">
      <SvnVersion LocalPath="$(MSBuildProjectDirectory)" ToolPath="$(ProgramFiles)\CollabNet Subversion Client">
        <Output TaskParameter="Revision" PropertyName="Revision" />
      </SvnVersion>
      <Time>
        <Output TaskParameter="Year" PropertyName="Year" />
        <Output TaskParameter="Month" PropertyName="Month" />
        <Output TaskParameter="Day" PropertyName="Day" />
      </开发者_运维百科Time>
      <FileUpdate Files="MasterPage.master" Regex="svn revision: (\d+)\.(\d+)\.(\d+)\.(\d+)" ReplacementText="svn revision: $(Year).$(Month).$(Day).$(Revision)" />
    </Target>

As you can see above the "BeforeBuild" task updates the masterPage.master file with the YYYY.MM.DD.SVNVERSION stamp.

How can I achive this with TFS as the source control. How do I get the TFS build number?

Assuming you mean Team Build, the $(BuildNumber) property contains the current build number.

See http://blogs.msdn.com/aaronhallberg/archive/2008/02/12/team-build-2008-property-reference.aspx for a full reference of available properties.

If you're just running MSBuild, I don't believe it generates/applies an overall build number (each project will have an individual, possibly auto-incremented, version number in its AssemblyInfo.cs [by default] file). You can dynamically get this version number for a specific assembly using the System.Reflection.Assembly class at runtime.

Update

As of TFS 2010, the 'BuildNumber' variable is no longer automatically passed to the MSBuild process by TFS. TFS 2010 now uses Windows Workflow as its internal build engine, so if you want the build number, you'll have to modify your build definition to include it, as mentioned in this MSDN article.
