Getting all types that implement a custom attribute

hey, is using Assembly.GetTypes() and iterating them really the best way to get all types that implement a custom attribute? i was thinking i could just have a static enumerable in the attribute class like so:

class ExampleAttribute : System.Attribute
{
  private static readonly List<ExampleAttribute> implementingTypes = new();
  
  public ExampleAttribute()
  {
    implementingTypes.Add(this);
  }

  public static List<ExampleAttribute> ImplementingTypes => implementingTypes;
}

class ExampleAttribute : System.Attribute
{
  private static readonly List<ExampleAttribute> implementingTypes = new();
  
  public ExampleAttribute()
  {
    implementingTypes.Add(this);
  }

  public static List<ExampleAttribute> ImplementingTypes => implementingTypes;
}

object reference not set to instance of object on a static method call

so im trying to use an opengl binding package (Veldrid.OpenGLBinding) but, when i call any of the methods, it says "Object reference not set to an instance of an object". I'm guessing I'm not using it right but it has absolutely zero documentation so I'm lost

❔ generic class in generic method

im trying to have this method:

        public void AddPrefab<T, C>(C args) where T : Prefab<C> where C : PrefabArgs
        {
            T.Create(this, args);
        }

        public void AddPrefab<T, C>(C args) where T : Prefab<C> where C : PrefabArgs
        {
            T.Create(this, args);
        }

where each thing that inherits Prefab has a PrefabArgs generic type thing, like, a Prefab "player" could be Player<PlayerPrefabArgs>, and you can call this method like

AddPrefab<Player>(new PlayerPrefabArgs());

AddPrefab<Player>(new PlayerPrefabArgs());

but the problem im having is this just isnt working how id like it to, i have to do

AddPrefab<Player, PlayerPrefabArgs>(...);

AddPrefab<Player, PlayerPrefabArgs>(...);

like it doesnt know how to infer the type or something

Can someone please help me understand this StackOverflow answer?

I'm working with NAudio and am trying to get the full device name of a wavein device, but the device name is cut off at 32 characters. DirectSound lets me get the full name of the OUTPUT devices, but it doesnt even map properly. This stackoverflow post has the answer but im not smart enough to understand it https://stackoverflow.com/questions/1449162/get-the-full-name-of-a-wavein-device
