c# - Global exception handler in Web API not getting called -

-

similar question asked here issue concerning 404 error.

i have added elmah global handler described here. if raise error in code elmah catches fine, if have sql error ef via controller example, not caught - exception message returned in json 500 error.

according article there few cases exception can't caught case doesn't seem 1 of them.

can please explain why global error handler in webapi won't catch sql exception?

here's handler:

public class unhandledexceptionfilter : exceptionfilterattribute {     public override void onexception(httpactionexecutedcontext context)     {         elmah.errorlog.getdefault(httpcontext.current).log(new elmah.error(context.exception));     } }

and here's it's registered in webapiconfig.cs

public static void register(httpconfiguration config) {     ----     config.filters.add(new unhandledexceptionfilter()); }
