How To Return A Class With Static Members

[Liagapi]

Suppose in my project I'm referencing another project as follows:

using static ProjectA;

Prior to using the static keyword in the using statement, one of my methods was able to create an instance object of a class called Products, set the values of its members, and return the instance object as shown below:

Product prod = new Models.Product();
prod.ID = unit.ID;
prod.Dept =unit.Department;
return prod;

Now I'm getting errors saystating that I cannot use an instance object to access members of the Product class. I tried to resolve this by going to the Product class in ProjectA and added the static keyword to the ID and Dept properties. But the big problem now is I do not have the instance object of the Product class so I cannot return it and I get an error related to that. How do I return the Product class instance in this situation?
