OAuth.dll using higher version than referenced assembly of webMatrix.data and webmatrix.webdata

Question

I am getting this error:

Assembly 'Microsoft.Web.WebPages.OAuth, Version=3.0.0.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35' uses 'WebMatrix.WebData, Version=3.0.0.0, 
Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version 
than referenced assembly 'WebMatrix.WebData, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35'

1. I have followed this post Could not load file or assembly 'WebMatrix.Data` from the stack overflow and installed it

   PM> Install-Package WebMatrix.Data but not working.

2. then i deleted packages folder and restore it that also not working.

3. I tried the following:

   PM> Uninstall-package Microsoft.AspNet.WebPages.OAuth then installed it again.that's also not working.

First thing notice able, if I tried to install the nuget packages seperately----

 PM> Install-Package WebMatrix.WebData

and

PM> Install-Package WebMatrix.Data

Then its providing me only this vrsion 2.0.30506

I don't know how to resolve this issue. The web.config file is something like this.

<dependentAssembly>
<assemblyIdentity name="WebMatrix.Data" publicKeyToken="31bf3856ad364e35" culture="neutral" /> 
<bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" />

Answer 1

take a look at Nuget listing for WebMatrix.WebData and WebMatrix.Data

https://www.nuget.org/packages/WebMatrix.Data/

https://www.nuget.org/packages/WebMatrix.WebData/

notice that they were

last updated on Friday, May 31, 2013

These assemblies were moved into

Microsoft ASP.NET Web Pages Data 3.2.3 https://www.nuget.org/packages/Microsoft.AspNet.WebPages.Data/

Microsoft ASP.NET Web Pages Web Data 3.2.3 https://www.nuget.org/packages/Microsoft.AspNet.WebPages.WebData/

Because the names of the assembly names have remained the same, but the locations have changes, Nuget Package Manager gets confused -- failing to correctly add / remove the references from your project.

What to do?

• in references , remove any reference to WebPages.Data and/or WebPages.WebData
• in package manager, run

Install-Package Microsoft.AspNet.WebPages.WebData

Install-Package Microsoft.AspNet.WebPages.Data

• in your Web Project , right click on "references" -> click "Add reference" -> click "Browse..." navigate in your packages directory to packages\\Microsoft.AspNet.WebPages.Data.3.2.3\\lib\\net45 double click WebMatrix.WebData.dll
• in your Web Project , right click on "references" -> click "Add reference" -> click "Browse..." navigate in your packages directory to packages\\Microsoft.AspNet.WebPages.Data.3.2.3\\lib\\net45 double click WebMatrix.Data.dll

finally:

in your Web.config , remove or comment out any references to dependentAssembly named WebMatrix.Data and/or WebMatrix.WebData

Re-build and run

Answer 2

So the problem was: the package Microsoft.AspNet.WebPages.WebData was not installed properly, so I uninstalled and re-installed it (along with all the dependent packages).

To do this, I ran:

Uninstall-Package Microsoft.AspNet.WebPages.OAuth  
Uninstall-Package DotNetOpenAuth.AspNet  
Uninstall-Package DotNetOpenAuth.OAuth.Consumer 
Uninstall-Package DotNetOpenAuth.OAuth.Core 
Uninstall-Package DotNetOpenAuth.OpenId.RelyingParty 
Uninstall-Package DotNetOpenAuth.OpenId.Core  
Uninstall-Package DotNetOpenAuth.core 
Uninstall-Package Microsoft.AspNet.WebPages.WebData 

Install-Package Microsoft.AspNet.WebPages.WebData 
Install-Package DotNetOpenAuth.core 
Install-Package DotNetOpenAuth.OAuth.Core 
Install-Package DotNetOpenAuth.OpenId.RelyingParty 
Install-Package DotNetOpenAuth.OpenId.Core  
Install-Package DotNetOpenAuth.OAuth.Consumer 
Install-Package DotNetOpenAuth.AspNet  
Install-Package Microsoft.AspNet.WebPages.OAuth  

I then used the instructions from Dave Alperovich above to add the correct version of the references. Now the error is gone.
