Umbraco 7.1.9 on Windows Server 2012 (Azure)

Question

We recently deployed a Umbraco 7.1.9 application on a Windows Server 2012 VM hosted by Azure. The application works #1 locally on our developer machines but when we deploy the website on the VM we get this error:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

We installed the latest version of .NET Framework, every updates on the server and we can't get it to work.

Anyone got a similar issue?

EDIT : Useful thread here...

This didn't help...

I haven't seen that problem yet but I'm diffing Web.config to upgrade from 7.1.4 to 7.1.9 today and I've noticed two things that might help you.

1. This was added recently:

    <add assembly="System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> 

2. There is nothing like this in Web.config for System.Web.Http:

    <dependentAssembly> <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0"/> </dependentAssembly> 

Makes me wonder if the answer to your problem might be adding this:

<dependentAssembly>
    <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>

Or this ( seen here ):

<dependentAssembly>
    <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.2.0" newVersion="5.2.2.0" />
</dependentAssembly>

Not sure it will be helpful for anyone else having this issue as it is very specific to our project.

We added the LowercaseRoutesMVC4 package that depends on AspNetWebApi.Core which is an unlisted package. It references a bad version of System.Web.Http . I uninstalled this package, used the LowercaseUrls property in my route configuration instead of the NuGet package and now everything works as expected.
