System.Web.MVC reference



The current release has a reference to System.Web.Mvc 2.0.0.

If you deploy any app to a shared hosting environment where MVC2 is not installed and your app is on MVC3 or MVC4, LinqtoTwitter will fail to load correctly.

You're correct, but what happens when you use an assemblyBinding with a bindingRedirect, like this:
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="" newVersion="" />
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="" newVersion="" />
        <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="" newVersion="" />
The tradeoff is that I can support later versions with a config file setting. However, if I upgraded to MVC 4.0, then lower versions are no longer supported and break for existing applications. If I remove the MVC authorizer, then users have an extra dependency on another DLL.

I'm open to your ideas, but need to be cautious about creating a situation that causes problems.

Hi JoeMayo,

Actually i was getting the following exception;

Could not load file or assembly 'System.Web.Mvc, Version=, 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)

I tried the assemblyBinding with a bindingRedirect with no success at all, my case was very special indeed, the hosting provider denied to install MVC2, i end up downloading the source code and build LinqToTwitter referencing the System.web.mcv dll.
