Autodesk.Windows reference missing

[Anonymous]

Hello all, yesterday, the below worked and has done for years, today code will not compile stating Autodesk.Windows "The type or namespace name 'Windows' does not exist in the namespace 'Autodesk' (are you missing an assembly reference?)", anyone else had this??? Using windows 10.

foreach (Autodesk.Windows.RibbonTab tab in Autodesk.Windows.ComponentManager.Ribbon.Tabs)

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.

<ItemGroup>
  <PackageReference Include="Revit_All_Main_Versions_API_x64" Version="2021.*" IncludeAssets="build; compile" PrivateAssets="All" />
</ItemGroup>

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.
