I copied your code that was installed with the Nevron software.
That is C:\Program Files (x86)\Nevron Software\Nevron .NET Vision 2019.1 for VS2019\Examples\Chart\Mvc
I chose the solution Nevron.Examples.Chart.Mvc.VS2017.sln since it was the most recent version in the example.
I am running visual studio 2019 community edition. The first problem I have overcome that was four corrupted references.
System.Web.Http.WebHost
System.Web.Razor
System.Web.WebPages
System.Web.WebPages.Razor
I found I had to delete them and re-establish the references but on running the application another error occurred.
GlobalFilterCollection was undefined in FilterConfig.cs
the reason for this was the reference to System.Web.Mvc was missing and on adding that reference the code would compile but a further error occurred and it would not run.
Parser Error Message: Could not load file or assembly 'System.Web.Mvc, Version=4.0.0.0, 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). So I have the incorrect file referenced. Currently I have an asp.net application and I wish to change to MVC.
