ASP.NET Core MVC MiddlewareFilter exception not meaningful -
currently have problem thrown exceptions when enabling middlewarefilter. add filter developer exceptions quite meaningless (the complete stacktrace missing).
services.addmvc(options => options.filters.add(new middlewarefilterattribute(typeof(myfilter)))) public class myfilter { public void configure(iapplicationbuilder applicationbuilder, requestlocalizationoptions options) { applicationbuilder.userequestlocalization(options); } } stacktrace filter:

microsoft.aspnetcore.diagnostics.developerexceptionpagemiddleware.<invoke>d__7.movenext() so i'm unable track down exceptions when enabling filter. have ideas how correct this? (i need use middlewarefilters)
after checking middlewarefilterbuilder implementation looks "expected" behavior...
// ideally want experience of middleware pipeline behave same if registered, // in startup. in scenario exception thrown in middelware later in pipeline gets propagated // earlier middleware. // check if later resource filter threw exception , propagate middleware pipeline. if (!resourceexecutedcontext.exceptionhandled && resourceexecutedcontext.exception != null) { throw resourceexecutedcontext.exception; } that explains why see
system.exception: test exception @ microsoft.aspnetcore.mvc.internal.middlewarefilterbuilder.<>c.<<buildpipeline>b__8_0>d.movenext() instead of
system.exception: test exception @ myproject.myrepository.<fetch>d__9.movenext() also noticed, above code in dev branch, not in master branch in aspnet/mvc repo...
all seems candidate question/issue in mvc repo.
