Ignore, was missing the AdWindows dll from C:\Program Files\Autodesk\Revit yyyy. Somehow it was removed from my solution...

You're my hero. I am new to .net programming, as well as programming itself, so I am not sure where and how to learn all the APIs. I was searching for what .dll to reference into my project for, what feels like, forever. I knew I needed Autodesk.Windows, but all my google searches were returning nothing useful. If you, or anyone else, know(s) a good resource for Autodesk .net programming then would you mind telling me. Thank you!

Hey,

I have the same problem. What was the using statement to get the references working?

Thanks

hi, this reply might be a little too late,

It's AdWindows.dll, should be on the same file path as RevitAPI & RevitAPIUI

I was facing the same issue today,

after a few months away from my RevitAPI code,

I forgot how I can re-reference the missing library..

fortunately the file still recorded on the Recent page..

Still have no idea what caused this problem though.

You could use the package Revit_All_Main_Versions_API_x64 .

Includes these assemblies:

RevitAPI.dll
RevitAPIUI.dll
AdWindows.dll
UIFramework.dll

Something like this on the csproj for the Revit 2021.

See yaa!

Hi,

I installed "Revit_All_Main_Versions_API_x64" with NuGet.

Now when I go to MyProject->References->"Add Reference", the newly installed package "Revit_All_Main_Versions_API_x64" or "AdWindows.dll" is not available.

I tried "Browse" and searched the entire drive C: but nothing is found.

How can I add it to the project?

Thanks!

If you installed the Nuget Revit_All_Main_Versions_API_x64 correctly with your right Revit version, your project gonna use the reference inside the package that contains:

RevitAPI.dll
RevitAPIUI.dll
AdWindows.dll
UIFramework.dll

And you don't need to add any other reference from your installed Revit.
