• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Managed SimConnect Support Multiple Versions of P3D


I'm trying to figure out how a Managed (C#) application (WinForms) can support both P3DV4 and P3DV5. When I build against the new version of the Managed DLL for V5, it won't work in V4, and vice versa.

Any hints or do I need two versions of the program?

Add a flag at the top of the code that is e.g. int _ver = 0; so that 0 = P3Dv4 and 1 = P3Dv5. Then add code where you need to change between versions e.g.

if _ver == 0 then
// load the v4 libraries
// load the v5 libraries

Set the flag accordingly before compiling. That way you'll only need one codebase but you will need to create two versions of the app.

Thank you for that and it makes sense, is there a way to detect this in code (which version of the sim is loaded?) I say this because It seems like a cart-and-horse "race" because I need to load the correct library depending on sim and I was hoping to not rely on the user for this. In this regard, FSUIPC seems easier but I wanted to provide an alternative to this dependency.
