@aadog I cannot reproduce this issue in my machine with same .NET 9.0 version:

@Olina-Zhang *.csproj add
<PropertyGroup> <OutputType>WinExe</OutputType> <TargetFramework>net9.0-windows</TargetFramework> <Nullable>enable</Nullable> <UseWindowsForms>True</UseWindowsForms> <PlatformTarget>x64</PlatformTarget> <_SuppressWinFormsTrimError>true</_SuppressWinFormsTrimError> <PublishAot>true</PublishAot> <TrimMode>partial</TrimMode> </PropertyGroup>

Trimming/AOTing WinForms Apps is not supported at this time. When setting it, the form designer cannot be loaded successfully.
Related issue: #10741.

This is on our radar but there is not a specific schedule to get this working. It is expected that you will get trim warnings with data binding and we need to redesign how databinding and trimming work.

What options do we have to not crop parts
