如何从Visual Studio 2015中启用IIS Express中的详细错误

Question

Using VS 2015 and Firefox browser. When my code runs into an error I see it in the Output window, but would prefer seeing it in the browser. Right now all I get is a 500 error with no stack.

Thanks!

You'll want to look into the <customErrors /> of your web.config (example below):

<configuration>
   <system.web>
      <customErrors defaultRedirect="GenericError.htm"
                    mode="RemoteOnly">
         <error statusCode="500"
                redirect="InternalError.htm"/>
      </customErrors>
   </system.web>
</configuration>
