Upgrade to 4.7.0 - Recaptcha missing assembly reference

Hey guys,

I'm dealing with an assembly reference exception when upgrading an Umbraco install from version 4.5.2 to 4.7.0. (Win 2003, .NET Framework 4, ASP.NET 4)

When I look at the debug/trace on the home page, I'm getting following error message for each macro:

Unable to load one or more of the types in assembly 'Recaptcha, Version=1.0.4.0, Culture=neutral, PublicKeyToken=null'. Exceptions were thrown:
System.IO.FileLoadException: Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

  at umbraco.macro.GetXsltTransformResult(XmlDocument macroXML, XslCompiledTransform xslt, Dictionary`2 parameters)
  at umbraco.macro.loadMacroXSLT(macro macro, MacroModel model, Hashtable pageElements)

What I would like to understand is:

1) Why is the error being thrown in each macro? There are no XSLT extensions that use Recaptcha nor do any of the macros on the page use Recaptcha.

2) ASP.NET MVC 1 has not been installed on the server (and it has not been GAC'ed) neither are there any MVC dll's in the bin folder - how can this have worked in 4.5.2?

3) I managed to workaround by copying the MVC 2 dll's to the bin folder, and adding an assembly binding entry in the web.config like so:

<dependentAssembly>
   <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
   <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
</dependentAssembly>

I think this is kind of hacky however, perhaps one of you smart guys know of a better solution? :-)

I am getting an assembly reference exception when I want to add a new XSLT file in the umbraco backoffice. I go to the Developer section, rightclick + create the XSLT folder, type a name in the box that appears, submit, and this is what I get. I am not using ReCaptcha, nor am I using MVC.

Hi,

Check out this thread for a fix to that error: http://our.umbraco.org/forum/developers/xslt/19383-referencing-catcha-dll-breaks-xslt

I think you must have the Recaptcha DLL in your /bin/ somewhere, maybe from the Contour Contrib package?

Okey Dokey,

I hit this error on .net 4 running Umbraco 4.7.1.1.

This is the full runtime node so you can get a bit more context but I only had to add the last dependentAssembly node and it was fixed.

  <runtime>
    <!-- Old asp.net ajax assembly bindings -->
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
