Broadly speaking, Ruptura's packages can be split into three different categories of functionality:
Vezel.Ruptura.Injection and Vezel.Ruptura.Hosting provide the ability to inject the CoreCLR runtime and managed assemblies into a target process.
Vezel.Ruptura.Memory provides function hooking, memory manipulation, and call tracing capabilities.
Vezel.Ruptura.System provides managed wrappers around operating system APIs and kernel objects.
You can pick and choose which of these packages you would like to use. For example, if you already have a working solution for injection, you may want to just use Vezel.Ruptura.Memory for its function hooking APIs, or Vezel.Ruptura.System for convenient Win32 API access. You could also use Vezel.Ruptura.Injection and Vezel.Ruptura.Hosting to inject your managed assembly, but choose to implement your own function hooking method.
Either way, simply use dotnet add package <name>
to add the relevant package(s) to your project and start writing code. No further configuration is required.
