Order of global filters in ASP.NET Core

Question

I have two global exception filters in Startup ``` config.Filters.AddService(typeof(ExceptionFilter)); ``` and ``` config.Filters.AddService(typeof(JsonExceptionFilter)); ``` I was always under impression that if the same filter is added first it is executed first. But when I've added `ExceptionFilter` first it is executed second. UPDATE 1 `ConfigureServices` method: ``` services .AddMvc( config => { config.Filters.AddService(typeof(ExceptionFilter)); config.Filters.AddService(typeof(JsonExceptionFilter)); }); ```

Accepted Answer

With MVC, you can specify an order value that determines the order of execution for your filters. I don't know if the same applies to ASP.NET Core, and I don't have an IDE in front of me to check. Would you mind trying this?

```
config.Filters.AddService(typeof(ExceptionFilter), 2);
config.Filters.AddService(typeof(JsonExceptionFilter), 1);
```

Even if that isn't it, check to see if there is another overload of `AddService` that does accept a parameter to specify the order.
