[BUG] Buggy .Equal() method on c# aspnetcore3 when using TypeSpec's byte data type

[AnReZa]

We're using Microsoft TypeSpec to auto-generate c# classes. However, there is a problem with the auto-generated .Equals method. In the default .mustache file of the openapi generator, there's a check for #isContainer which determins, if a regular comparison or .SequenceEqual should be used:

/// <summary>
/// Returns true if {{classname}} instances are equal
/// </summary>
/// <param name="other">Instance of {{classname}} to be compared</param>
/// <returns>Boolean</returns>
public bool Equals({{classname}}? other)
{
    if (other is null) return false;
    if (ReferenceEquals(this, other)) return true;

    return {{#vars}}{{^isContainer}}
        (
            {{name}} == other.{{name}} ||
            {{^vendorExtensions.x-is-value-type}}{{name}} != null &&{{/vendorExtensions.x-is-value-type}}
            {{name}}.Equals(other.{{name}})
        ){{^-last}} && {{/-last}}{{/isContainer}}{{#isContainer}}
        (
            {{name}} == other.{{name}} ||
            {{^vendorExtensions.x-is-value-type}}{{name}} != null &&
            other.{{name}} != null &&
            {{/vendorExtensions.x-is-value-type}}{{name}}.SequenceEqual(other.{{name}})
        ){{^-last}} && {{/-last}}{{/isContainer}}{{/vars}}{{^vars}}false{{/vars}};
}

However, contrary to my expectation for the TypeSpec bytes data type (defined as an array of bytes), it doesn't use the SequenceEqual comparison, but the regular == one, which doesn't work for byte arrays in c#. Why is that?

bytes gets converted into a type: string, format: byte data type, which seems odd to me. Is that right?

Right now, it correctly generates a property of type byte[] in c#, but the equals method doesn't work, as it uses .Equals instead of the correct SequenceEqual.
