Moving to a WIN 10 machine from a WIN 7 and getting Could not load file or assembly 'System.Web.Mvc,

Daniel Main asked on March 26, 2019 21:30

Running into an odd problem, Got a new development machine running windows 10, was on a Win 7. We house our changes in TFS, and I have installed the version of Kentico we are using 9.X onto my new development machine.

So I grab the latest version of the site and clean it then build it in VS, then I attempt to run it...

Here i the full error I am getting:

Server Error in '/' Application.
Parser Error

Any ideas on what is happening? This refrence:

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0"/>
</dependentAssembly>

is commented out in the web config (works in WIN 7) and the site is running on .net 4.5.

What .Net Framework version is installed on your machine?

Did you get any errors during package restore?

Currently it is supposed to be 4.7.2 but as you can see in the copy it seems to be using Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.7.3163.0

I did mange to resolve one issue, but another has crept up, I got the reference that was commoneted out fixed, but now coming up with this:

Server Error in '/' Application.

It is almost looking like LinqToTwitter does not like Win 10.

Ok, after some more fiddleing, I may have narrowed down the problem, seems to be residing in the System.Linq not sure how that reference fell off, in the version that is on the Win7 box it is alive and well.

Currently stumped.
