XmlSerializer exception after rebuild the generator

[limeniye]

Introductory information

I have an IIncrementalGenerator.
It generates me the code through the XmlSerializer.

	serializer = new XmlSerializer(type);

After the first Rebuild, my generator starts tracking changes in .xml files and generates C# types based on that.
It works well.

Description of the problem

If I do a Rebuild a second time, I get an error when creating the XmlSerializer object.

The problem happens, because my schema has an DataAnnotations attribute:

	[System.Xml.Serialization.XmlIgnore()]
	private System.Collections.ObjectModel.Collection<Student> _students = new();
	[System.ComponentModel.DataAnnotations.Required(AllowEmptyStrings = true)]
	[System.Xml.Serialization.XmlArray("students")]
	[System.Xml.Serialization.XmlArrayItem("student")]
	public System.Collections.ObjectModel.Collection<Student> Students
	{
		get => _students;
		private set => _students = value;
	}

FileNotFoundException: Could not load file or assembly 'System.ComponentModel.Annotations, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

What I've tried

• I've tried to redirect assembly identity to 4.2.1.0, 4.5.0.0 and 4.2.0.0

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.ComponentModel.Annotations" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.2.0.0" newVersion="4.2.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

  <ItemGroup>
    <None Update="App.config">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup> 

• I've tried to clear the XmlSerializer cache
• I've tried to use the RedirectAssembly code from stackoverflow through the project Target:

  <UsingTask TaskName="Shmyndra.Mavlink.Tasks.TestRebuildGenerator" AssemblyFile="$(ProjectDir)..\SomeProjectName.Tasks\bin\$(Configuration)\netstandard2.0\SomeProjectName.Tasks.dll" />

  <Target Name="PreBuild" BeforeTargets="Build">
    <TestRebuildGenerator />
  </Target>

• I've tried to use the following lines:

  <PropertyGroup>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
    <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
  </PropertyGroup>

I've tried to use reflection and a lot of other things but currently I'm stuck.
