Other than using XSLT as you've mentioned, there is also an option to do this on the send port:


Select the native XmlTransmit send pipeline
Add your processing instructions to the
XmlAsmProcessingInstructions property as per this
example


Create Processing Instruction in BizTalk Map
I've created an ASP.NET MVC 4 app using visual studio 2012 RC on Windows 8 release preview. I downloaded and installed the WIF toolkit and used the "Identity and Access" option in the solution menu to add my Access Control Service metadata endpoint. Tested locally and all is well. When I deployed to my free azure website however I get the yellow screen saying


  "Could not load file or assembly 'System.IdentityModel.Services,
  Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or
  one of its dependencies. The system cannot find the file specified."


These assemblies aren't referenced in the project, so I added them, sent to output to the bin folder and redeployed. I then got a message about the assembly probably being tampered with. Does anyone know how to overcome this?

EDIT
Adding local causes this error


  Could not load file or assembly 'System.IdentityModel.Services' or one
  of its dependencies. Strong name signature could not be verified.  The
  assembly may have been tampered with, or it was delay signed but not
  fully signed with the correct private key. (Exception from HRESULT:
  0x80131045)


In the web config the module is deinfed as

&lt;system.webServer&gt;
    &lt;validation validateIntegratedModeConfiguration="false" /&gt;
    &lt;modules&gt;
      &lt;add name="WSFederationAuthenticationModule" type="System.IdentityModel.Services.WSFederationAuthenticationModule, System.IdentityModel.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler" /&gt;
      &lt;add name="SessionAuthenticationModule" type="System.IdentityModel.Services.SessionAuthenticationModule, System.IdentityModel.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler" /&gt;
    &lt;/modules&gt;
  &lt;/system.webServer&gt;


Thanks
