Upgrading WebGrease to version 1.3.0 causes error only on production server (4)

First off, answers to this question,do NOT solve my error:

Upgrading WebGrease to version 1.3.0 gets me error

I have the following bindingredirect on my production server:

<dependentAssembly>
    <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-1.3.0.0" newVersion="1.3.0.0" />
</dependentAssembly>

I have the following DLL's on my production server that are required for the Microsoft ASP.NET Web Optimization Framework:

  1. System.Web.Optimization.dll 1.0.0.0 (this is NOT pre-release version)
  2. Antlr3.Runtime.dll 3.3.1.7705
  3. Webgrease.dll 1.3.0.0

I am getting the following error:

Could not load file or assembly 'WebGrease, 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)

I have checked the GAC, I have deleted all Temporary ASP.NET folders, I have tried removing the newVersion attribute from my config <bindingRedirect>. I am not sure what is telling ASP.NET to look for WebGrease 1.0


Finally figured out why this was not working for me despite other users saying that it was working for them.

I had the following binding redirection in my web.config file to force the System.Web.Optimization assembly to use the newer version instead:

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-1.3.0.0" newVersion="1.3.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

</configuration>

It was just like other users had, but it didn't work. Then I used the fusion log viewer (Fuslogvw.exe) to figure out more information and discovered that the binding process didn't even look at the redirect instruction.

Finally figured out that there must not be an XML namespace on the root ... . If I remove the following from my <configuration> element it works: xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"

Also, just make sure you have the following XML namespace specified on the <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> element.

Finally!!


I got the same problem. I have a solution with different projects within. I have disinstalled Microsoft.AspNet.Web.Optimization and WebGrease from all projects, and deleted manually all bin and obj folders.

Then I have installed Microsoft.AspNet.Web.Optimization only in the project that need this package.

At this point I have deleted all files from packages folder.

When I had opened Visual Studio again it had started to reinstall all packages from scratch.

In the end I did a git-diff and this was the result:

Change the upper code in Web.config to the following

<assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-1.3.0.0"/> </dependentAssembly>

Cannot start default project

Try installing WebGrease in your project. You could achieve this by going to Tool> Library Package Manager> Manage Nuget packages for solution and than search webgrease at online category.
