namespace Enums
{
    [OverrideToStringDefault(1)]
    public enum Color
    {
        Red,
        Green,

        BMW
    }
}

namespace Models
{
    internal enum Device

        Phone = 2,
        PC = 4,
        Monitor = 8
    }
}

The followning will be generated:

// <auto-generated />

using Enums;
using Models;

public static class EnumStringConverter
{
    public static string FastToString(this Color enumValue)
    {
        return enumValue switch
        {
            Color.Red => nameof(Color.Red),
            Color.Green => nameof(Color.Green),
            Color.Blue => nameof(Color.Blue),
            _ => nameof(Color.Green)
        };
    }

    public static string FastToString(this Device enumValue)
    {
        return enumValue switch
        {
            Device.None => nameof(Device.None),
            Device.Phone => nameof(Device.Phone),
            Device.PC => nameof(Device.PC),
            Device.Monitor => nameof(Device.Monitor),
            _ => throw new ArgumentOutOfRangeException(nameof(enumValue), enumValue, null)
        };
    }
}

Configure

<PropertyGroup>
    <RootNamespace>FastEnumToString</RootNamespace> 
    <FastEnumFallbackValue>Default</FastEnumFallbackValue> 
</PropertyGroup>

• First: uses the first avalilable enum member in the switch's default arm,
• Throw: throwing an ArgumentOutOfRangeException
