Revit 2020 SDK Sample project build errors

[jarkko.hoivala5K6CD]

Hi,

What could be the problem with these errors:

1>------ Build started: Project: DWGFamilyCreation, Configuration: Debug Any CPU ------
error CS0246: The type or namespace name 'Autodesk' could not be found.. same with: 'IExternalCommand','ExternalCommandData','View','Document'
error CS0103: The name 'Autodesk' does not exist in the current context
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Refences are OK (RevitAPI & RevitAPIUI) and NET framework 4.7.2

my bad, didn't read through op's question. references are ok..

Are you referencing the RevitAPI/RevitAPIUI.dll from a Revit 2022 installation? Those are built against .net framework 4.8. Maybe try changing your project's TargetFrameworkVersion from 4.7.2 to 4.8?

Got this working by creating new project with existing code. It's a workaround, but still wondering why .csproj file doesn't work as such.
