MSBuild Obfuscation Task

It is quite easy to integrate obfuscation to a build process with the help of the MSBuild obfuscation task, that is implemented by the NuGet package: https://www.nuget.org/packages/ArmDot.Engine.MSBuildTasks/

🛈 Task Parameters

You can find description of all available parameters of the task here.

After adding the MSBuild obfuscation task to a project, you are to modify the project file to activate the task:

<Target Name="Protect" AfterTargets="AfterCompile" BeforeTargets="BeforePublish">
  <ItemGroup>
     <Assemblies Include="$(ProjectDir)$(IntermediateOutputPath)$(TargetFileName)" />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
    Inputs="@(Assemblies)"
    ReferencePaths="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')"
    SkipAlreadyObfuscatedAssemblies="true"
  />
</Target>

Often a release build is the only one to be obfuscated. To enable obfuscation for the release build only, use MSBuild condition:

<Target Name="Protect" AfterTargets="AfterCompile" BeforeTargets="BeforePublish"
  Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
  <ItemGroup>
     <Assemblies Include="$(ProjectDir)$(IntermediateOutputPath)$(TargetFileName)" />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
    Inputs="@(Assemblies)"
    ReferencePaths="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')"
    SkipAlreadyObfuscatedAssemblies="true"
  />
</Target>
