Microsoft released a preview of their .NET ProtoBuf client for Phoenix/Hbase on Nuget.org in June. I've found it worked well but the API was unfamiliar to me. As I learned it, I implemented a .NET Framework System.Data IDbConnection, IDbCommand et al wrapper API around it, named Garuda.Data. It makes access to Phoenix/Hbase from .NET code feel almost like SqlConnection, SqlCommand, etc for SQL Server - Check it out: https://www.nuget.org/packages/Garuda.Data/

Here is the github project repo: https://github.com/dwdii/GarudaUtil

And some example code:

using (IDbConnection phConn = new PhoenixConnection())
{
    phConn.ConnectionString = cmdLine.ConnectionString;

    phConn.Open();

    using (IDbCommand cmd = phConn.CreateCommand())
    {
        cmd.CommandText = "SELECT * FROM GARUDATEST";
        using (IDataReader reader = cmd.ExecuteReader())
        {
            while(reader.Read())
            {
                for(int i = 0; i < reader.FieldCount; i++)
                {
                    Console.WriteLine(string.Format("{0}: {1}", reader.GetName(i), reader.GetValue(i)));
                }
            }
        }
    }                        
}
