EnvBinder.Bind throws the following error: Invalid cast from 'System.String' to 'System.Enum'

[MrDave1999]

Given the following code:

new EnvLoader().Load();
var settings = new EnvBinder().Bind<AppSettings>();
Console.WriteLine("Provider=" + settings.Provider);

public enum DirectLineProviders
{
    InDirectLine,
    DirectLineAzure
}

public class AppSettings
{
    public DirectLineProviders Provider { get; set; }
}

And the .env file:

PROVIDER=InDirectLine

The following exception is thrown when running the application:

Unhandled exception. System.InvalidCastException: Invalid cast from 'System.String' to 'DirectLineProviders'.
   at System.Convert.DefaultToType(IConvertible value, Type targetType, IFormatProvider provider)
   at System.String.System.IConvertible.ToType(Type type, IFormatProvider provider)
   at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider)
   at DotEnv.Core.EnvBinder.Bind[TSettings](EnvValidationResult& result)
   at DotEnv.Core.EnvBinder.Bind[TSettings]()
   at Program.<Main>$(String[] args) in C:\Users\syslan\Documents\Visual Studio 2022\DotNet-Env-Example\Program.cs:line 22

Convert.ChangeType does not support conversion to enums and that is why this error occurs.
