AutoCAD 2025 was released, at least I think it was. I'm too lazy to find out.
AutoCAD 2025 has migrated from .NET Framework 4.7.2 to .NET 8 (previously named .NET Core).
With this change you might need to set the BaseIntermediateOutputPath in order to use a common code base between AutoCAD years. I've found that you can create a "Directory.Build.props" file and put it in the root folder of your solution. Then within the file add:
<Project>
<PropertyGroup>
<Deterministic>true</Deterministic>
<BaseIntermediateOutputPath Condition="'$(BaseIntermediateOutputPath)'=='' ">obj\$(MSBuildProjectFile)\</BaseIntermediateOutputPath>
</PropertyGroup>
</Project>
This will move the project build from the "obj" folder to a "obj/ProjectFileName" folder. This will cause the build for each project to go into their own folder and prevent projects from mingling and causing duplicate info that prevents the build from building.
