I am testing dhtmlxGantt with Asp .net MVC for the first time but unfortunately I have this error.
Anyone can help me please.
Thank you.
Hello Sonya,
I don’t specialize in ASP.NET so I’m not familiar with that error.
Maybe the following answers to that question will help you:

If that doesn’t help you, please send me the archive with your project so that I can reproduce the issue locally and check if there is something wrong with the configuration.
