Why is my Target not executed?

I have the following Targets file that is imported into my .csproj file, One of the targets (AfterAddPostAction) never fires. Why not? (Sorry it's so verbose but MSBuild is shit at abstraction and CallTask doesn't see Property values set inside the Target containing the CallTask element.)

Solution

DependsOnTargets is the primary way to chain tasks into the sequence. But if you have sequence A->B->C implemented via DependsOnTargets (B depends on A) and call target A, then B and C will not be executed. But if you call C, then both A and B are executed.

On the contrary the target that has target A mentioned in AfterTargets attribute will be executed after A is executed.

That's why in your case if you want to use DependsOnTargets it is important which target you execute.
