Why can't I get to a project method

[simsenVejle]

Hi,
I am starting on a solution, with several projects. ViewModel, Model, Views, DAL and the UI project.

In ViewModel I have made a folder called it Account and the cs file called CategoriViewModel.cs - In this I have a method called LoadCategories. Here I want to get to the DAL layer.

I have made a project reference to the DAL. In the CategoriViewModel.cs file I have made a using DAL.Account;

then in LoadCategories I want to go through DalCategory to get to the method GetCategories by writing DalCategory.GetCategories - vs accept the DalCategory but not the method. When writing the dot I only get to choose between Equals and ReferenceEquals. I have double checked that the GetCategories is public. And it is. Now I do not know what to do - I hope one of you can help me explaining what to do.

Best regards

Simsen

It is an instance method and you're trying to use it as a static method.

Thank you very much. I have now googled it, and I think I have understood the difference between an instance and a static method
