UPDATE 10:29 MST on 11/7
Oddly enough if I move the attribute out of the ComponentModel folder back into the root of the Common project the code works fine. I can't imagine what's possibly referencing the old namespace after all of the references were refactored for the InflowHealth.Common.ComponentModel namespace.
It's almost like there is some reference hiding somewhere that's not code-based but rather runtime and dynamic, but I sure don't see it when looking through all find results of InflowHealthErrorContext.

Of new interest, when I commented out the line to use the custom attribute to inherit routes, and use the default one, it still blew up. Of further interest, the namespace it's looking for InflowHealth.Common.InflowHealthErrorContextAttribute is actually the old FQN before I refactored it and moved it to a folder (and namespace) ComponentModel.
UPDATE 07:42 MST on 11/6
I believe I've identified that the issue is related to another custom attribute I'm using to inherit actions. This attribute is added to the HttpConfiguration like this:
public static void MapInheritedAttributeRoutes(this HttpConfiguration config)
{
config.MapHttpAttributeRoutes(new InheritanceDirectRouteProvider());
}
The implementation of that attribute is pretty simple:
public class InheritanceDirectRouteProvider : DefaultDirectRouteProvider
{
protected override IReadOnlyList<IDirectRouteFactory> GetActionRouteFactories(HttpActionDescriptor actionDescriptor)
{
return actionDescriptor.GetCustomAttributes<IDirectRouteFactory>(true);
}
}
It appears that inheriting this InflowHealthErrorContext attribute is causing issues, but I'm not sure exactly what the issue is. I've tried:
- Removing
Inherited = falseso that it is inheritable. - Removing
AllowMultiple = truejust because that was misconfigured.
Those did not change the error.
ORIGINAL POST
I have a very simple attribute in a Common assembly shared by a couple Web API applications. As simple as this is I just can't figure out what would cause this exception.
I have tried to collect Fusion logs on this, but it's not logging them.
This is the Attribute:
using System;
namespace InflowHealth.Common.ComponentModel
{
[AttributeUsage(AttributeTargets.Method, Inherited = false, AllowMultiple = true)]
public sealed class InflowHealthErrorContextAttribute : Attribute
{
// This is a positional argument
public InflowHealthErrorContextAttribute(string errorContext)
{
ErrorContext = errorContext;
}
public string ErrorContext { get; }
}
}
This would be used on a route to later provide some extra context to the automated error logging done inside of a filter:
[Authorize(Roles = Roles.ALL_ADMINS)]
[Route("api/ControlPanelApi/PayerClassifications")]
[InflowHealthErrorContext("Error getting payer classifications.")]
public IHttpActionResult GetPayerClassifications(int clientId, bool showAllRows)
{
return Ok(GetData(payerClassificationManager, clientId, showAllRows));
}
Upon loading the application, when Web API Routes are registered, it fails. Here is the line it's breaking on:
GlobalConfiguration.Configure(WebApiConfig.Register);
It's throwing this exception:
Could not load type 'InflowHealth.Common.InflowHealthErrorContextAttribute' from assembly 'InflowHealth.Common, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
