httpclient C#

//example code
//var lst = await service.ConnectHttpClient<User, List<User>>("api/User/GetUserInfoByUserId", new User() { UserId = 1 });
//var lst = await service.ConnectRestClient<User, List<User>>("api/User/GetUserInfoByUserId", new User() { UserId = 1 });

public async Task<M> ConnectHttpClient<R, M>(string apiUrl, R reqModel)
{
    M model = default(M);

    HttpClient client = new HttpClient();
    client.BaseAddress = new Uri(baseUrl);
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    HttpResponseMessage response = await client.PostAsJsonAsync(apiUrl, reqModel);
    if (response.IsSuccessStatusCode)
    {
        var res = response.Content.ReadAsStringAsync().Result;
        model = JsonConvert.DeserializeObject<M>(res);
    }
    return model;
}

public async Task<M> ConnectRestClient<R, M>(string apiUrl, R reqModel)
