Outside NuGet Packages

coopgodd — Sat, 29 Oct 2022 23:23:14 GMT

Hey everyone,

I'm looking to use some NuGet packages in my Revit Add-in application. However, I can't seem to find a way to do this. Even when I download the packages Revit crashes and gives the following error:

System.IO.FileNotFoundException

Has anybody experienced this issue and can shed some light on where I need to go to fix this issue. For example, I'm trying to install the package npgsql.

Much appreciated!

Did you put the dll package in the same folder when testing in Revit? I suppose you are copying your plugin .dll and .addin to tests in Revit, you need to copy the 'npgsql' dll as well.

Usually, FileNotFoundException happens when the dll is not found...

But could be another thing, sometimes is kinda tricky to work with third-party packages and Revit.

Thanks for the reply!

Add the ddl into the revit folder or into the project/application folder? Im confused...

Thanks!

Hi @coopgodd,

Once you create you plugin and build it, you need to copy both your manifest file and plugin dll file to the location below.
Under Windows 10 - C:\ProgramData\Autodesk\Revit\Addins\20xx\ (The ProgramData folder is hidden by default)
Since you want to use external dll, you need to copy the same to the target folder above. I think setting CopyLocal to true in visual studio might have he same effect although I am not sure in your case.

This isn’t working either unfortunately…

I tried manually placing it, the copy local setting, and I also tried the Embed Interop Types setting as well (which sounds like exactly what I need but does not function with my application…)

any further thoughts would be appreciated!
