@vkmohan1689 for this to work, you are going to need some general MSBuild knowledge and know the appropriate places to hook into the build process. This isn't going to work out of the box. We can offer suggestions, but the docs here are probably the place to start:

• https://learn.microsoft.com/dotnet/android/building-apps/build-targets
• https://learn.microsoft.com/dotnet/android/building-apps/build-properties

$(AfterGenerateAndroidManifest) is an example of a build-time extension point.

If ".NET Reactor" is a product, they could build this support for you. I imagine it would be a NuGet package that supports all .NET MAUI platforms.
