[dotnet-sdk-9.0.100-rc.2.24470.13] The windowsforms/datagridview demo App build with error: Property 'XXX' does not configure the code serialization for its property content

[CancanTang]

We are doing Application compatibility testing with this application against the latest .NET 9 SDK. When retarget the application to net9.0 and build with the latest .NET 9 SDK, it failed with error: Property 'xxx' does not configure the code serialization for its property content

After the investigation, it is related to a .NET 9 breaking change https://github.com/dotnet/docs/issues/42724

You can fix the CodeDOM Serialization configuration for properties if you want

• Attribute with the DesignerSerializationVisibilityAttribute OR
• Attribute with the DefaultValueAttribute OR
• Amend a private bool ShouldSerialize[Property] method, which controls the serialization at Design Time.

Steps to Reproduce (for bugs)

1. Cd to WinformsSamples\datagridview\CSWinFormDataGridView
2. Change TargetFramework to net9.0-windows in the CSWinFormDataGridView.csproj.
3. dotnet build with 9.0.100-rc.2.24470.13.

Expected Result: build successfully without error Actual Result: build failed with Property 'xxx' does not configure the code serialization for its property content
