"Make reference types nullable" must use nullable type in SetRelatedEntity()

[randombyte-developer]

Tool and Version
EarlyBoundGenerator V 2.2024.5.16

Describe the bug
I wanted to try out #311. It generates nullable types. When compiling the generated code there is a compile error:

Possible null reference argument for parameter 'entity' in 'void Entity.SetRelatedEntity<Contact>(string relationshipSchemaName, EntityRole? primaryEntityRole, Contact entity)'

The relevant line of code is
this.SetRelatedEntity<Contact>("account_primary_contact", null, value);

value can be null in this case. SetRelatedEntity() does handle null values correctly but the nullable entity type has to be used like this:
this.SetRelatedEntity<Contact?>("account_primary_contact", null, value);

To Reproduce
Steps to reproduce the behavior:

1. Generate the code for an Account with nullable types enabled.
2. Compile it.

Expected behavior
No errors.

Additional context
My C# project file looks like this:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup Condition=" '$(Configuration)' == 'Release' ">
		<SignAssembly>true</SignAssembly>
		<AssemblyOriginatorKeyFile>........snk</AssemblyOriginatorKeyFile>

	</ItemGroup>
</Project>

A workaround is to not enable the INotifyPropertyChanging pattern in the EBG config.

Looks like with the INotifyPropertyChanging, also need to null out the PropertyChanged and Property Changing events:

public event System.ComponentModel.PropertyChangedEventHandler? PropertyChanged;
		
public event System.ComponentModel.PropertyChangingEventHandler? PropertyChanging;

@daryllabar If there's anything to test or try out, just tell me.
