Framework issue maybe? Is your app pool set to .net framework version 4 not 2?

Or are you missing a dll file from your server maybe?

Thanks

Thank you very much for your suggestion Carl.

I think you may be on to something because I think (?) this started when I reimaged my machine and moved to Windows 10.

I have checked IIS Manager and the application pool used for my web site in IIS uses .Net CLR V4.0 (V4.0.30319).

However this error occurs when recompiling in Visual Studio BEFORE I even try and run the site using IIS or VS Debug.

So I still have not solved the issue and would appreciate any more suggestions, particularly considering that I have just moved to Windows 10.

Maybe try running nuget package restore?

How many projects are in your solution? Are there any conflicting dependencies there.

Also, are you targeting .net 4.0 or 4.5 + in your solution?

Thanks

Hi again Carl,

Do you mean to run a Nuget "package restore" on what package ? Umbraco ? or .Net ? or what ?

I have only one "Project" in my "Solution".

When I select "Properties" on that project, the Target Framework is ".NET Framework 4.5.1"

So I can not see any conflicting framework conflict ? I am not sure what to try next ?

What can you supply the code from one if the mentioned view files?

Thanks

Hi again

I have an update on the symptoms of this problem

(1) I have copied my solution back to a machine running Windows Server 2012 R2 and Visual Studio 13 and found that the error does not occur in that environment

(2) Another (new) error has emerged :

    Error CS1061 'HtmlHelper<RenderModel>' does not contain a definition for 'RenderPartial' 
     and no extension method 'RenderPartial' accepting a first argument of type 
     'HtmlHelper<RenderModel>' could be found (are you missing a using directive or an assembly 
     reference?) TeraTastic02 C:\Clancy\A_TeraTastic\Dev\TeraTastic02\TeraTastic02
     \Views\TTMaster2.cshtml 88

This error also does not occur on Windows Server 2012 R2 and Visual Studio 13.

This adds weight to the hypothesis that the error is caused by the move to Windows 10 and Visual Studio Enterprise 2015. Any help resolving this would be appreciated.
