Automatically Register Minimal APIs in ASP.NET Core

There is another interesting way to register API controllers. I was experimenting with
<pre><code class="language-csharp">var assembly = Assembly.Load(&quot;ExternalControllers&quot;);
builder.Services.AddControllers().AddApplicationPart(assembly);
</code></pre>
and it’s very promising. You can automatically register controllers from another assembly.

This is great! Conveniently came across this while working on a Minimal API project
