I have 2 applications, App A and App B.

App A has class CLASS1 with properties and methods

App B has class CLASS2 which has different methods that uses CLASS1

I have no problem creating a reference of the namespace that has CLASS1 on CLASS2 on the BLL of App B

But I also use CLASS1 on the presentation layer of App B, is there a way to pass all the properties and methods of CLASS1 to the presentation layer of App B using CLASS2 or any other way without having to rewrite the CLASS1 on the BLL of App B again?

Thanks, help must appreciate it.

It looks like you might need to change your architecture. Since AppA and AppB are different applications and need related classes (class 1 and class2), it is best to create a separate class library project having both these classes in it and then reference this project in AppA and AppB.

This way you can use both the classes in both the projects without needing to rewrite them.

HTH,
