ASP.NET (C#) Question

Error Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

I have a small web application. Which was working fine until I added two genericHandler in my application.


I have made the following changes for the http handler

<system.web>
<authentication mode="Forms" >
<forms protection="All" timeout="720" defaultUrl="Default.aspx" loginUrl="Login.aspx" >
</forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>
<compilation debug="true" targetFramework="4.0" />

<httpHandlers>
<!--Code Log Handler-->
<add verb="*" path="*.aspx" type="System.Web.UI.PageHandlerFactory" />
<add verb="*" type="InfoDomeNewUI.Handler.SendOWA" path="SendOWA.ashx" />
<add verb="*" type="InfoDomeNewUI.Handler.SendSOS" path="SendSOS.ashx" />
</httpHandlers>
<customErrors mode="Off">
<error statusCode="404" redirect="Templates/PageNotFound.html" />
</customErrors>
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<!--Code Log Handler-->
<add name="LogHandler1" path="SendOWA.ashx" verb="*" type="InfoDomeNewUI.Handler.SendOWA"/>
<!-- SMS SENDER-->
<add name="SendSOS" path="SendSOS.ashx" verb="*" type="InfoDomeNewUI.Handler.SendSOS"/>
</handlers>
</system.webServer>

I am using asp.net4.0 and C#. I am not using MVC

On local host it is working fine.

But when I am hosting the published code it is giving me the above error.

Stack Trace:-

Answer

I found the problem. Instead of adding a class (.cs) file by mistake I had added a Web API Controller class which added a configuration file in my solution. And that configuration file was looking for the mentioned DLL (Microsoft.Web.Infrastructure 1.0.0.0). It worked when I removed that file, cleaned the application and then published.
