I am working on a .net 4.8 c# library project and I am using a Shared Project within it to help with versioning. When I attempt to add a WPF User Control under the shared project, it is not an available template. If I create it under one of the other projects in the solution the option is there and it creates the user control. However, if I then move that user control to the shared project, it splits the xaml and cs files apart and no longer sees that they are connected. This is the same thing if I attempt to add an existing xaml file to the shared project.

I have checked a bunch of the payload stuff in the installer and currently have W10 and W11 SDK also included. Is there something I am just missing here on how to get this to work? I have worked with WFP / XAML stuff in library many times in the past, but never with a shared project.

This image show what it looks like when trying to add to a project.

    Hi Sean, were you sucessful with WFP user control in a shared project. I am working on something similar for Revit and am having the same issue. I am able to create the user control, however there is some kind of improper linkage between the code behind and the form, and it seems to be due to it being in a shared project. Did you have any luck in the end with this?

    After moving to a new machine and starting a new shared project in .NET 8 on the current build of VS the WPF behavior has resolved. Now when I create User Controls the code behind is associated as I'd expect. Still suffer from the MSBuild Props, but that is far less of an obstacle. I assume my WPF issue was fixed in an update even if unintentionally. One item to note is that I use a template User Control most the time so its copy and paste, but that wasn't working either previously.
