public class CustomDataStore : IDataStore
{
    private readonly DbContext _context;
    public CustomDataStore(DbContext context)
    {
        _context = context;
    }
    public async Task StoreAsync(string key, T value)
    {
        var entity = new Entity()
        {
            Key = key,
            Value = JsonConvert.SerializeObject(value)
        };
        _context.Entities.Add(entity);
        await _context.SaveChangesAsync();
    }
    public async Task GetAsync(string key)
    {
        var entity = await _context.Entities.FirstOrDefaultAsync(e => e.Key == key);
        if (entity != null)
        {
            return JsonConvert.DeserializeObject(entity.Value);
        }
        return default(T);
    }
