AppBuilder class

hello there iam currently trying to think of a solution so i can make myself a AppBuilder without needing to reference all projects directly basicly i have a Program.cs from a wpf app in Project B but in project A i want to be able to say something like

cs 
builder.AddSingleton<LoggerForProjectA>();

cs 
builder.AddSingleton<LoggerForProjectA>();

how could that be done?

}

public static class Extensions
{
  public static void AddWpfApp(this IServiceCollection collection)
  {
    collection.AddSingleton<...>();
  }
}

in project A: builder.AddWpfApp();

its not only about logging its just as an example

project B gets to control what gets registered even though project A actually does the registration

this would be in project B then right? never heard of that

it's what you see a lot of libraries do like automapper has an extension method AddAutomapper() which handles all the registration for you uhh, the other way around actually i think, now that i re-read your post project B is the app you're actually running, right and project A is some kind of library or whatever? in that case you would have an extension method with AddSingleton<LoggerForProjectA>() in project A somewhere and call the extension method in project B

the entire project is a 3 Layer wpf application having 3 main parts UI Core and HostProcess HostProcess is the first thing that starts wich boots up the entire application and launches the Launcher wpf project the wpf project might need some parts of core then wich is a class library same with other ui components one other side part we also have which is the plugin managment like for logging we make a own project wich implements our plugin structure and load it in with the host process before the wpf apps start

sounds like it'll still work then yeah

iam refactoring the entire solution architecture for the 3rd time now as the team still isnt happy with it xd

Have the bootstrapper be separate from the core so it can reference projects directly Or include it in the outermost layer @Dropps

DroppsOP•3y ago

its not having a bootstrapper its not a web app

Doesnt matter, if you are encountering circular references, you need to change something I use bootstrapper as a generic term to describe the code that initializes and starts your app It should be in your presentation layer Or separate from the three distinct layers
