Environment

Microsoft Visual Studio 2022
Version 17.9.3

.NET version

.NET 6 (we use)
.NET 8

Did this work in a previous version of Visual Studio and/or previous .NET release?

Works in the same Visual Studio 2022 Version 17.9.3 or previous versions, but targeting to .NET Framework 4.8.

Issue description

We have a custom Component and ComponentDesigner those are used to create/populate multiple DataTable and DataColumn in the design-time.

After migrating to .NET 6 we are experiencing with an issue that each DataColumn serialize some properties to .Designer.cs and .resx files that looks needless and just increase file size and noise.

Previous code:

this.dataColumn35.ColumnName = "DischargedDate";
this.dataColumn35.DataType = typeof(System.DateTime);

Current code:

dataColumn35.Caption = "DischargedDate";
dataColumn35.ColumnName = "DischargedDate";
dataColumn35.DataType = typeof(System.DateTime);
dataColumn35.DefaultValue = resources.GetObject("dataColumn35.DefaultValue");
dataColumn35.Namespace = "";

and .resx

  <data name="dataColumn35.DefaultValue" mimetype="application/x-microsoft.net.object.binary.base64">
    <value>
        AAEAAAD/////AQAAAAAAAAAMAgAAAEhTeXN0ZW0uUHJpdmF0ZS5Db3JlTGliLCBDdWx0dXJlPW5ldXRy
        YWwsIFB1YmxpY0tleVRva2VuPTdjZWM4NWQ3YmVhNzc5OGUFAQAAAB9TeXN0ZW0uVW5pdHlTZXJpYWxp

        AAAACw==
</value>
  </data>

So, ton of Caption, DefaultValue, Namespace properties are added when changing the form design in new Windows Forms Designer..

Is this issue already known? How can be this fixed?
