Current Behavior

When using .net communityToolkit maui for two projects in a solution, one main executable and one shared library, the following error occurs

MainTest-master\MainTest-master\MainTest\CommunityToolkit.Maui.SourceGenerators\CommunityToolkit.Maui.SourceGenerators.Generators.TextColorToGenerator\TimePickerTextColorTo.g.shared.cs(41,89,41,124): warning CS0436: The type ‘ColorAnimationExtensions_TimePicker’ in ‘CommunityToolkit.Maui.SourceGenerators\CommunityToolkit.Maui.SourceGenerators.Generators.TextColorToGenerator\TimePickerTextColorTo.g.shared.cs’ conflicts with the imported type ‘ColorAnimationExtensions_TimePicker’ in ‘MainTest.Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’. Using the type defined in ‘CommunityToolkit.Maui.SourceGenerators\CommunityToolkit.Maui.SourceGenerators.Generators.TextColorToGenerator\TimePickerTextColorTo.g.shared.cs’.

Expected Behavior

No build errors should occur

Steps To Reproduce

2. Reference the shared project from the main project
3. Then i add the community toolkit to the shared code projet
4. Then build the main project, build warnings/errors occur
