Errors in c-sharp code code generation export using https://app.swaggerhub.com/apis

Description

There is code generation errors using c-sharp

The abstraction used for this object called MoneyObject (see below)

See how this translates

public partial class AllOfTransactionResourceAttributesHoldInfo : HoldInfoObject,IEquatable, IValidatableObject
{
/// Initializes a new instance of the class.
public AllOfTransactionResourceAttributesHoldInfo( amount = default(), foreignAmount = default()) : base(amount, foreignAmount)
{
}

public partial class HoldInfoObject : IEquatable, IValidatableObject
{
/// Initializes a new instance of the class.
public HoldInfoObject(AllOfHoldInfoObjectAmount amount = default(AllOfHoldInfoObjectAmount), AllOfHoldInfoObjectForeignAmount foreignAmount = default(AllOfHoldInfoObjectForeignAmount))

Eventually the MoneyObject is defined as you would expect as per the spec

/// Initializes a new instance of the <see cref="AllOfHoldInfoObjectAmount" /> class.
public AllOfHoldInfoObjectAmount(string currencyCode = default(string), string value = default(string), int? valueInBaseUnits = default(int?)) : base(currencyCode, value, valueInBaseUnits)
 {
}

Everywhere MoneyObject is used as the base it just does not insert the type on the first level so it should have been
Should have been

public AllOfTransactionResourceAttributesHoldInfo(AllOfHoldInfoObjectAmount amount = default(AllOfHoldInfoObjectAmount), AllOfHoldInfoObjectForeignAmount foreignAmount = default(AllOfHoldInfoObjectForeignAmount)) : base(amount, foreignAmount)
 {
 }

There is a bug when swagger creates the output

Likewise here - Error

    public AllOfTransactionResourceAttributesCashback(string description = default(string),  amount = default()) : base(description, amount)
    {
    }

Should have been

    public AllOfTransactionResourceAttributesCashback(string description = default(string), AllOfCashbackObjectAmount amount = default(AllOfCashbackObjectAmount)) : base(description, amount)
    {
    }

2. Also this is an error

    IEnumerable<System.ComponentModel.DataAnnotations.ValidationResult> IValidatableObject.Validate(ValidationContext validationContext)
    {
        foreach(var x in BaseValidate(validationContext)) yield return x;
        yield break;
    }

_CS0103 The name 'BaseValidate' does not exist in the current context

I can manually code the missing parts

Start by reproducing the C# export from the supplied OpenAPI schemas, focusing on the generated HoldInfoObject and CashbackObject constructors and IValidatableObject.Validate method. Done means the generated code includes the referenced MoneyObject types and no longer refers to an undefined BaseValidate member, while compiling successfully.
