I am trying to add some middleware so that any unhandled exceptions I catch and log it but experiencing some difficulties in doing so. Not been able to find a lot on this and for some odd reason my code doesn't seem to be entering the catch block. Seems like it is gracefully handling this and even interrogating the dictionary I can't see the exception.
What I want to happen is, enter the catch block grab the exception and log the stack trace.
The code:
public class Startup
{
public void Configuration(IAppBuilder app)
{
var config = new HttpConfiguration();
app.Use(typeof(FooHandler));
app.UseWebApi(config);
}
}
public class FooHandler : OwinMiddleware
{
private static readonly ILog Logger = LogManager.GetLogger(typeof(FooHandler));
public FooHandler(OwinMiddleware next) : base(next)
{
}
public override async Task Invoke(IOwinContext context)
{
if (Logger.IsErrorEnabled)
{
try
{
await Next.Invoke(context);
}
catch (Exception ex)
{ // DOESN'T FALL INTO HERE!
Logger.Error(message, ex);
}
}
}
}
public class FooController : ApiController
{
public Task<IHttpActionResult> Get()
{
throw new Exception("Foo Bar");
}
}
