c# - AssemblyBinding BindingRedirect not working for MVC4 app with T4MVCExtensions -

we have large .net web application mvc3, using t4mvc. upgraded mvc4, , except t4mvcextensions (version 3.6.5 nuget) still dependent on system.web.mvc version 3. runtime dependencies you're supposed setup in web.config should redirecting assembly bindings, don't seem be. following exception occurs:

index out of range. must non-negative , less size of collection. parameter name: index  description: unhandled exception occurred during execution of current web     request. please review stack trace more information error , originated in code.   exception details: system.argumentoutofrangeexception: index out of range. must non-negative , less size of collection. parameter name: index 

we've got following in our web.config file, should mapping it, doesn't seem -

<runtime> <assemblybinding xmlns="urn:schemas-microsoft-com:asm.v1">   <dependentassembly>     <assemblyidentity name="system.web.helpers"                       publickeytoken="31bf3856ad364e35" />     <bindingredirect oldversion="1.0.0.0" newversion="2.0.0.0" />   </dependentassembly>   <dependentassembly>     <assemblyidentity name="system.web.mvc"                       publickeytoken="31bf3856ad364e35" />     <bindingredirect oldversion="1.0.0.0-3.0.0.0" newversion="4.0.0.0" />   </dependentassembly>   <dependentassembly>     <assemblyidentity name="system.web.webpages"                       publickeytoken="31bf3856ad364e35" />     <bindingredirect oldversion="1.0.0.0" newversion="2.0.0.0" />   </dependentassembly> </assemblybinding> 

i've enabled fusion log, verify craziness really, , see that, yes indeed, seem trying use mvc3 binary, , not going 4:

any ideas rock, since i've burned bunch of hours on this.

i had similar assembly binding issue, after manually upgrading set of mvc3 projects mvc4. despite having assembly binding elements in web.config, getting errors similar t4mvc errors telerik mvc extensions.

the fusion log viewer useful confirmed 2 versions of system.web.mvc being loaded application domain.

in end, removing namespace root configuration element in project's root web.config resolved issue.

so, web.config this:

<?xml version="1.0" encoding="utf-8"?> <configuration xmlns="http://schemas.microsoft.com/.netconfiguration/v2.0"> <!--... elements deleted clarity ...--> </configuration> 

and after removing namespace looks this:

<?xml version="1.0" encoding="utf-8"?> <configuration> <!--... elements deleted clarity ...--> </configuration> 

this blog post has more information erroneous namespace: http://www.dotnetish.com/runtime/xmlnshttpschemas-microsoft-com-netconfigurationv2-0/
