C:\il\a.vb(4) : error BC30390: 'yyy.i' is not accessible in this context because it is 'Private'. The 'friend' access modifier signifies that none other than the entities in the same dll or assembly can access its variables. Since the instance variable i is being accessed from another assembly named 'a', an access violation is reported.
These are access specifiers to provide security to applications. here is a guideline to the difference of each. The keywords 'internal' and 'protected' are access modifiers. If any member in a class is qualified with access modifier 'internal', then it is friend to the current assembly but not outside of it. This means any member or class (but not the dervied classes) within the current assembly can access it.
