Getting blank page after deploying ASP.NET MVC application on IIS

Question

I have deployed an ASP.NET MVC application on my windows 10 system IIS. I have given full permission to IIS_IUSRS of both the root folder and web.config file. i.e.

My web.config is:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
      <add key="webpages:Version" value="3.0.0.0" />

Browser console is :

You get a 500 server error on hitting the specified url. Nothing much over there. Can you create a new website and run it on a different port and see if it works. — Durga Prasad

500 is always a server issue. Meaning you have to look in logs server side. But it could be caused by client side passing in bad parms. Your trace doesn't like the 2 get requests. You iis logs can help but best place to check is the event logs. — JWP

you are getting the error 500.19 which is a configuration error. it means there is something wrong with your web.config file.

you could try to remove below code from your web.config file:

    <system.codedom>
      <compilers>
          <compiler language="c#;cs;csharp" extension=".cs" type="microsoft.codedom.providers.dotnetcompilerplatform.csharpcodeprovider, microsoft.codedom.providers.dotnetcompilerplatform, version=2.0.0.0, culture=neutral, publickeytoken=31bf3856ad364e35" warninglevel="4" compileroptions="/langversion:default /nowarn:1659;1699;1701" />
          <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="microsoft.codedom.providers.dotnetcompilerplatform.vbcodeprovider, microsoft.codedom.providers.dotnetcompilerplatform, version=2.0.0.0, culture=neutral, publickeytoken=31bf3856ad364e35" warninglevel="4" compileroptions="/langversion:default /nowarn:41008 /define:_mytype=\&quot;web\&quot; /optioninfer+" />
      </compilers>
  </system.codedom>

if you still face and issue enable detailed error in iis for your site.

Open the IIS console on the webserver machine.
Double-click the Error Pages option:

Select the Edit Feature Settings... option:

Change the default setting from the third option, Detailed errors for local requests and custom error pages for remote requests to the second option, Detailed errors:

5)restart iis .
