    Thanks Griff for your reply. I tried right clicking on Engine3 in the At the moment Engine.dll is stored at Documents\Visual Studio 2015\Projects\SuperAdventure3\Engine3 But if I create a new project called such as Test010119 then I want to copy the Engine3.dll over to my new project so I can reuse some of the classes in Engine3. I don't know where to move Engine3.dll so it's recognized by the new program. Brian

    BTW Brian, you do realize you can have a better username than "Member 14154627" if you want? It's easy to do, just hover over your username at the top right and select "Settings" - change "Your Display Name" to one that is free ("Brian" is taken, but "Brian The Great" isn't for example - though that last may be a little presumptuous :laugh: ). Click "Save My Settings" and you have a new display name

      Using a step by step guild I created a "Engine" project in the solutions explorer and added classes to this "Engine project. In the main code I was able to refer to the "Engine" project by using "include Engine;. I noticed that when compiled C# had created a Engine.dll that contained all the classes. I was wondering where the library of dll's are kept so I could add this engine.dll to the library to use in the future for some other code. I'm pleased that you can create a lot of libraries to handle varibles and procedures which makes coding the main program much easier as you can use code such as '_player.CurtrentLocation.Description' and '_player.CurrentHitPoint' to refer to parts of the program within the DLL. Also there is no need for extra variables within the brackets, so this is possibles 'DisplayCurrentLocation()' making the code more tidier. Brian

      Hi, when you want to reuse a library (a managed code DLL file), you must “add a reference” and Visual Studio will include the DLL in your new project and copy it to the approapriate location. Copying the file yourself would not be sufficient. :)

            I don't tend to move them, instead I add a reference to the project, so I get the "latest version" if it gets updated (and a copy of the DLL will get added to your debug or release folders) or I add the project as an "Existing Project" to the solution which lets me update the DLL project from both solutions (that one takes a little discipline in order to not break other apps!) My Utilities are never constant - I add methods and classes to them all the time, and this way I get the "Latest version" to work with regardless of the project I am working on. The other solution is to install your DLL in the GAC but that means strong names and so forth: How to: Install an assembly into the global assembly cache | Microsoft Docs[^]

              Hi Luc. When you say reference do you mean add "using Engine3" to my code? If I did that then it still needs to know where to find Engine.dll, maybe your referring to something else. Brian

                There is a menu item that says either “add ...” or “add reference”, it may be a context menu for your project in the “solution pane”. Look around and you will find it. :)

                    I think I found it as Reference Manager. I have a choice of Solution under Projects or Solution under Shared Projects to browse for the dll file.There is also 'Browse recent' but I don't think that's the right one to use. Brian

                              It should be BrianTheLoin. It may have picked up Brain from my computer. When the tech installed the operating system he typed in Brain instead of Brian by mistake. Brian

                                    The assembly would need to become part of the project; easiest way to do so is to create a "bin" folder (or similar) and drop them all there, with "Copy to target" to true. When building, the assemblies would be copied to the build-folder.

                                        Hi Luc. I'm using the 2015 version of Visual Studio. Do you know if it's still possible to download the 2015 version should something happen to my 2015 version of Visual Studio? I'm told that there are errors in latest version of Visual Studio. Brian
