I have 2 programs from 2 different folders, currently, I have a class in SectionA.cs (namespace SectionA, class name Employee) and I want to reuse a method from the class in SectionB.cs (namespace SectionB), but I do not know how reference a class from SectionB.cs. I heard you have to use using SectionA; but it gives me this error
The type or namespace name 'SectionA' could not be found (are you missing a using directive or an assembly reference?) [SectionB]
The picture below shows the file directory, may I know how to reference the class in SectionA.cs to use it in SectionB.cs? Thank you in advance.
