Sure, there are lots of these properties in the MSBuild/TFS build target files,
and the purpose is to be able to extend the default behavior
and insert custom functionality at some point in the build process.
For example, in our TFS 2008 release builds, we have defined a build process by
extending most of the TFS extension points like this:
<GetDependsOn>
ReleaseBuildBeforeGet;
$(GetDependsOn);
ReleaseBuildAfterGet;
</GetDependsOn>
This will call the ReleaseBuildBeforeGet/ReleaseBuildAfterGet targets before
and after the standard Get functionality in the TFS build targets.
If you want to call a custom target somewhere inside the Get targets, you need
to find the definition of $(GetDependsOn) and override it:
<PropertyGroup>
<GetDependsOn>
BeforeGet;
ReleaseBuildBeforeCoreGet;
CoreGet;
ReleaseBuildAfterCoreGet;
AfterGet;
</GetDependsOn>
</PropertyGroup>
There is an important difference between doing this and just implementing the
<BeforeGet> and <AfterGet> targets, and that is that you can only have
one implementation of a target. This means that if you implement AfterGet in
one target file, and then you (or someone else) decides to implement AfterGet
in another target file this will override the default implementation.
By using the above “pattern” you make sure that your targets will always be
called, even is someone implement Before/AfterGet.
Hope that helps

Hi All,
Would someone be able to point me in the direction of the MS documentation on
GetDependsOn?
<GetDependsOn>
$(GetDependsOn);
</GetDependsOn>
I've had a look on the interwebs but nothing obvious jumps out.
Failing this - most likely :) - can anyone explain what this does?
Cheers Neil.
