Could not load file or assembly 'WebMatrix.Data, Version=3.0.0.0

Question

Could not load file or assembly 'WebMatrix.Data, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Answer 1

I had a similar problem, and I fixed it by doing the following:

1. Installing the package via package manager console(from visual studio) Use the following commands:

   PM> Install-package WebMatrix.Data

   PM> Install-package WebMatrix.WebData

2. Add a binding Redirect in Web.config file Between <runtime></runtime> tags:

   
   
   
   <dependentAssembly>
       <assemblyIdentity name="WebMatrix.Data" publicKeyToken="31bf3856ad364e35" culture="neutral"/>
       <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
   
   

3.I've copied both dlls from: /YourProject/packages folder to /YourProject/bin folder

(Optional) If you can't find the dlls in /YourProject/packages folder, try search for the dlls in /YourProject/bin/Debug folder, and copy/Paste them into /YourProject/bin folder instead.

It solved the problem for me.
