<!--Inpired by: https://stackoverflow.com/a/13849011/84522 -->
<Target Name="GetLastModifiedTime" BeforeTargets="BeforeBuild">
  <PropertyGroup>
    <LastModifiedTime>%(IntermediateAssembly.ModifiedTime)</LastModifiedTime>
  </PropertyGroup>
</Target>

<Target Name="CheckWasBuilt" AfterTargets="AfterBuild">
  <PropertyGroup>
    <!--WasBuilt is true only if a build/rebuild occurred. Can be used as a condition on other Targets that only need
        to run when after a build actually occurred. Those targets should be configured with:
        AfterTargets="CheckWasBuilt", Condition="$(WasBuilt) -->
    <WasBuilt>false</WasBuilt>
    <WasBuilt Condition="%(IntermediateAssembly.ModifiedTime) != $(LastModifiedTime)">true</WasBuilt>
  </PropertyGroup>
</Target>
