Question

I have updated to Microsoft.Web.Infrastructure package to version 2.0, but site fails when trying to load version 1.0

John Marshall 15

I have a Visual Studio project that has a reference to Microsoft.Web.Infrastructure version 2.0. I updated from version 1.0 using the Package Manager. Now the website gives me an error during startup:
Could not load file or assembly 'Microsoft.Web.Infrastructure, 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)

The package.config has an entry for version 2.0.0

The web.config has a <dependentAssembly> with a version of 2.0.0.0.

I have searched the entire project for 'Microsoft.Web.Infrastructure' and every place its found has version 2.0

Why is it trying to load version 1.0?

Hello, which version of Visual Studio are you using?

You can go to project Properties > Application > check “Auto-generate binding redirects” option.

For me, it was related to updating the Microsoft.SqlServer.Types...

Ridiculous.

Same problem here, cleaning bin and obj did no work, I'm not able to find reference to Version=1.0.0.0.

I'm able to build, the error arrises when I try to publish.

It seems that upgrading of this assembly does not add the reference to the web.config file. I have added following lines to my web.config:

 <dependentAssembly>
    <assemblyIdentity name="Microsoft.Web.Infrastructure" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-2.0.1.0" newVersion="2.0.0.0" />
 </dependentAssembly>

It resolved my problem

Hi @John Marshall,

Welcome to Microsoft Q&A!

Please close all running Visual Studio Instances and manually delete the bin and obj folders in your project folder.

Then, rebuild your solution.

Sincerely,

Anna
