Could not load type 'Microsoft.ApplicationInsights.Telemetry.Web.ApplicationInsightsModule'

Question

I have a Azure service which I developed using the C#.Net. When I compiled the solution it does it without any errors.

But when I run it, it throws the below error:

Could not load type 'Microsoft.ApplicationInsights.Telemetry.Web.ApplicationInsightsModule'

The following is the section where it points to when I run the solution .

<system.web>
     <compilation debug="true" targetFramework="4.5" />
     <httpRuntime targetFramework="4.5" relaxedUrlToFileSystemMapping="true" />
     <customErrors mode="Off" defaultRedirect="/Error/Error.html" />
     <pages controlRenderingCompatibilityVersion="4.5" />
     <httpModules>
        <add name="ApplicationInsights" type="Microsoft.ApplicationInsights.Telemetry.Web.ApplicationInsightsModule" />
     </httpModules>
</system.web>
