I am gradually converting my VS2008 solutions to VS2022.
I have a library of user controls that included ListView and TreeView controls that show files in the File System. They work find in the original solution on a test form but I cannot link to them from a new project. It sees the control but shows a blank control surface - although the class files can be edited.
I have spent the whole morning Googling with no success, can anybody advise me why a user control in one project cannot be linked to from another project please?
They work fine if I go back to my old PC with VS2008.

Hi @Jeff Gaines , welcome to Microsoft Q&A forum. What kind of project are you using, Windows Forms(C#) project? Does newly created User Control work well? Could you share a sample with us to reproduce this issue maybe? Besides, could you elaborate how you link the new project to the source files(what have you done to link to the source files)?

Hello TianyuSun-MSFT, thanks for your response, potted history follows:
Uninstalled VS2022 and cleaned the debris.
Installed VS2019 and copied over all my projects from my old PC.
Opened and converted my "JGFileObject" project, a Winforms project that contains a variety of controls and classes for finding/managing files, including a variety of File Explorer replacements.
It converted and ran perfectly, including the test form that has an example of each control on a TabControl for testing.
Opened and converted my "JGSimpleExporer" project which has links to controls and classes in the "JGFileObject" project. Immediately errors started to fill the error list, on checking it seems that for some controls only the link to the control had only brought in i.e. the .cs file and not the .Designer.cs file.
Deleted and added the links several times but had the same issue.
Decided that there might be a mistake in the file like NameSpace so deleted link, opened file in Ultraedit (text editor) checked and closed it (did NOT save as no changes made and Ultraedit won't save in those circumstances) went back to VS2019 re-added link and it worked. Did the same for all the other problem links and they all worked fine.
I really don't know if this need input from a technical wizard like you or just a wizard like Harry Potter :-)
I have to say I prefer the VS2019 IDE as there aren't so many pop ups to hide what I am trying to read. So far I haven't found any new/updated controls with added functionality though, but it's early days.
Just to add a bit more information this is still happening, for example in one of the directories in my control library I have 4 files:
FormSearch.cs
FormSearch.designer.cs
FormSearch.resx
JDirWalk.cs
I wanted to link to the Form and to JDirWalk. I selected FormSearch.cs and JDirWalk.cs as links but it did not include the designer.cs file nor the .resx file so the Form had no controls on it.
Hi @Jeff Gaines , thanks for sharing details. I thought you added references(user control dll file) to your project to link it, but now, I think I misunderstand this. You mean using “add as link” to directly add the .cs(user control) files right? If so, may I ask if the user controls projects have been added to your solution(Add > Existing Project… > )? If they haven't been added to your solution, could you have a try to add them to your current solution and test again?
Regards,
Tianyu
The visual studio 2022 IDE is a 64-bit application. Perhaps you need to rebuild your user controls for 64 bits.
RLWA32-6355 - thank you :-)
I am linking to the source files rather than a dll. I did a parallel development on another machine in VS2008 and it worked perfectly. When I link to a user control in VS2022 it sees the code file but the control surface is blank.
I have seen no benefits to V2022 over VS2008 at all so far. The original missing bits are still missing and it has a cluttered interface with boxes popping up every time I breathe asking what I want to do next!
