Showing Runtime Error in MVC application after deploy

Question

I made a new MVC Project in Visual Studio 2015, then published that package and uploaded into my Windows hosting. After extraction when I browse my URL it shows me this error message. But my application runs on locally just fine.

Have you set `customErrors` to `Off` to see the actual error? — ramiramilu, Sep 16 '16 at 07:36
@ramiramilu now this is showing "System.PlatformNotSupportedException: This operation requires IIS integrated pipeline mode." this error. — Khaled Md Tuhidul Hossain, Sep 16 '16 at 08:40

The custom error pages are not enabled for local in your code, you have to add mode="On". So customErrors looks something like this:

<customErrors mode="On" defaultRedirect="Error" redirectMode="ResponseRewrite">
  <error redirect="Error/NotFound" statusCode="404" />
</customErrors>
