AddMediator(config => ..) not working

[dschreib42]

The namespace and scope configuration is not respected in v.2.1.7, but in version v2.0.30 it's working fine...

 var builder = WebApplication.CreateBuilder(...);

 builder.Services.AddMediator(config =>
 {
     config.Namespace = "Foo.Generated";
     config.ServiceLifetime = ServiceLifetime.Scoped;
 });

Hi!
I just checked out the 2.1 branch, and ran this code

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddMediator(
    options =>
    {
        options.Namespace = "SomeNs";
        options.ServiceLifetime = ServiceLifetime.Transient;
    }
);

builder.Services.AddControllers();

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

var mediator = app.Services.GetRequiredService<SomeNs.Mediator>();

based on the ASP.NET Core sample in this repo. This worked fine, the generated mediator ends up in SomeNs and the lifetime is transient. I'll need more information to help you debug, for example what environment you have, .NET version etc..

I was using .NETt v6.0 with AutoFac on Windows 11

I added a sample for this using Autofac and .NET 6, seemed to work find here, unless I'm missing something..

Same issue. Cannot post repro but the abstractions and generator are installed in separate projects. I am not using autofac.

builder.Services.AddMediator(options =>
{
    options.Namespace = "Properties.API.Mediator";
    options.ServiceLifetime = ServiceLifetime.Scoped;
});

produces:

" Invalid configuration detected for Mediator. Generated code for 'Singleton' lifetime, but got 'Scoped' lifetime from options. "

Meanwhile using

[assembly: MediatorOptions(Namespace = "Properties.API.Mediator", ServiceLifetime = ServiceLifetime.Scoped)]

works properly

Mediator.SourceGenerator 2.1.7
.NET SDK 8.0.100
