Bin为Web应用程序部署了DLL优先于GAC的DLL？

Question

I am having a problem where an older GAC'd assembly is being used instead of a newer version assembly in the bin.

Server:

Assembly version: ASP.NET MVC 3 RC 1 (3.0.11029.0)
Full name: System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Code base: file:///C:/WINDOWS/Microsoft.Net/assembly/GAC_MSIL/System.Web.Mvc/v4.0_3.0.0.0__31bf3856ad364e35/System.Web.Mvc.dll
Deployment: GAC-deployed 

Development machine:

Assembly version: Unknown version (3.0.20105.0)
Full name: System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Code base: file:///C:/Windows/Microsoft.Net/assembly/GAC_MSIL/System.Web.Mvc/v4.0_3.0.0.0__31bf3856ad364e35/System.Web.Mvc.dll
Deployment: GAC-deployed 

The newer RTM version (3.0.20105.0) is in the bin directory of the application. However, the application is using the one in the GAC instead of the local bin. My experience from windows applications is the local bin deployed DLL always takes precedence because the GAC is checked only if the DLL isn't found in the same directory as the application. This convention appears to not be the case for a web application.

How can I force it to use my newer version bin deployed DLL (3.0.20105.0)?

Edit: I actually did try a binding redirect like so:

<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="3.0.11029.0" newVersion="3.0.20105.0" />

I tried several variations on the oldversion such as 0.0.0.0-4.0.0.0 . In all my attempts usually it either loaded the older version, or gave me this exception message:

Could not load file or assembly 'System.Web.Mvc' or one of its dependencies. 
The located assembly's manifest definition does not match the assembly reference. 

The binding log didn't have any errors except this was last two lines:

WRN: Comparing the assembly name resulted in the mismatch: Build Number
ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing terminated.

Answer 1

Answered is SO Dll in both the bin and the gac, which one gets used? Note, you must run strong name hijack or it will use the GAC version. I would retag this, it is not MVC specific.

您可以修改.config文件以使用程序集绑定重定向 ，并强制运行时根据需要加载不同的版本。
