- Change the <TargetFramework> from net8.0 to net8.0-windows . This is necessary needed to allow our the plugin to open a instantiate Windows form forms (Note: this plugin has only been tested to work on the Windows platform)
- Add the <UseWindowsForms>true</UseWindowsForms> attribute to the <PropertyGroup> . This will allow us to add a Windows form Form to our class library.
- Add the <EnableDynamicLoading>true</EnableDynamicLoading> attribute to the <PropertyGroup> . This will allow the CSI product to load our project as a plugin.
