如何将dapper与ASP.Net核心身份一起使用？

我有一个数据库，我试图将dapper与Core Identity结合使用以对数据库进行查询。但我被困在这一点上。我正在从identityUser的界面使用User：

public class User : IdentityUser
{

}

使用dapper为CRUD制作自定义用户存储。

 public class UserStore : IUserStore<User>
{
    private readonly string connectionString;

    public UserStore(IConfiguration configuration)
    {
        connectionString = configuration.GetValue<string>("DBInfo:ConnectionString");
    }

    internal IDbConnection Connection
    {
        get
        {
            return new SqlConnection(connectionString);
        }
    }
    public Task<IdentityResult> CreateAsync(User user, CancellationToken cancellationToken)
    {
**// HOW TO I RETURN A USER WITH DAPPER HERE?**
    }

    public Task<IdentityResult> DeleteAsync(User user, CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

    public void Dispose()
    {
        throw new NotImplementedException();
    }

    public Task<User> FindByIdAsync(string userId, CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

    public Task<User> FindByNameAsync(string normalizedUserName, CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

    public Task<string> GetUserIdAsync(User user, CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

    public Task<string> GetUserNameAsync(User user, CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

    public Task<IdentityResult> UpdateAsync(User user, CancellationToken cancellationToken)
    {
        throw new NotImplementedException();
    }

谢谢！
