I have an HTTPModule that I use to redirect traffic between a website in my data center and a website running on the Azure platform. This HTTPModule retrieves its redirect rules from Azure Table Storage.

Redirects work fine on my local dev machine as well as when running on Azure. However, when I deploy the module to my data center servers ( IIS 7, WS 2008 R2 Standard 64bit, .NET 4.0, ASP.NET 4.0 ) I receive the following error

Parser Error Message: Could not load file or assembly 'msshrtmi' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Line 124:                <add assembly="System.Web.DynamicData, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

Line 125:                <add assembly="System.Web.ApplicationServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

Line 126:                <add assembly="*" />

Line 127:            </assemblies>

Line 128:            <buildProviders>

Source File: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config    Line: 126 

"msshrtmi.dll" actually exists in my deployment bin directory.

If I remove this dll the data center site works fine but ---> System.TypeInitializationException: The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment' threw an exception.

 ---> System.IO.FileNotFoundException: Could not load file or assembly 'msshrtmi, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

   at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.InitializeEnvironment()

   at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment..cctor()

   --- End of inner exception stack trace ---

   at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.get_IsAvailable()the HTTPModule fails to load its configuration data from Table Storage and instead throws the following error

Also, I have manually included "Microsoft.WindowsAzure.ServiceRuntime.dll" as part of the deployment to ensure it is available on the data center servers.

Within the developer cmd:

gacutil /i "C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.0\bin\runtimes\base\x64\msshrtmi.dll"

gacutil /i "C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.0\bin\runtimes\base\x86\msshrtmi.dll"
