Add websocket functions

I am wanting to call the historical asset data API and I am wondering in what order is the data returned. Is it the most recent data first and then the last element in the list is the piece of data from longest ago?

I apologize for asking in this forum, but the CoinCap API docs are not very helpful.

namespace CoinCapApi.Types
{
    public enum TimeInterval
    {
        /// <summary>
        /// 1 minute
        /// </summary>
        M1 = 1,

        /// <summary>
        /// 5 minutes
        /// </summary>
        M5 = 2,

        /// <summary>
        /// 15 minutes
        /// </summary>
        M15 = 4,

        /// <summary>
        /// 30 minutes
        /// </summary>
        M30 = 8,

        /// <summary>
        /// 1 hour
        /// </summary>
        H1 = 16,

        /// <summary>
        /// 2 hours
        /// </summary>
        H2 = 32,

        /// <summary>
        /// 6 hours
        /// </summary>
        H6 = 64,

        /// <summary>
        /// 12 hours
        /// </summary>
        H12 = 128,

        /// <summary>
        /// 1 day (24 hours)
        /// </summary>
        D1 = 256
    }
}

Listing 1. The TimeInterval enum.

@ByronAP hello. I have a suggestion. The enum shown in Listing 1 is named TimeInterval. This is pretty generic.

I suggest you rename it something such as CoinCapTimeInterval or somesuch. This way, it would not clash with any other symbols that the developer consuming this library has named TimeInterval as well.

Add an extension method for IServiceCollection to make dependency injection one call.

The NuGet package won't install in my project. I am working on a .NET Framework 4.8 class library. Is there a way to make it support the .NET Framework? Thanks.
