如何使用EntityFramework Code First FluentAPI为bool属性设置默认值？

就像是:

Property(l => l.PropertyFlag).HasColumnType("bit").DefaultValue(1);

using (var client = new HttpClient())
{
 client.BaseAddress = new Uri(Url);
 client.DefaultRequestHeaders.Accept.Clear();
 client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));

 using (var task = client.PostAsJsonAsync(Url, body))
 {
    if (task.Result.StatusCode != HttpStatusCode.OK)
       throw new Exception(task.Result.ReasonPhrase);
 }

}

不确定为什么我们得到每个套接字地址(协议/网络地址/端口)的唯一用法通常是允许的xx.xxx.xxx.xx:80错误

System.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted xx.xx.xx.xx:80
at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult)
   at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, …

当我AsyncFileUpload用来上传100KB图像时,我没有收到任何错误消息.但是图像没有上传.我可以上传75KB图像.我正在使用IIS 6.0.

    <cc1:AsyncFileUpload ID="afuImg" Width="400px" runat="server" 
UploaderStyle="Traditional" ThrobberID="Throbber2"  
    OnClientUploadError="uploadErrorImg" 
    OnClientUploadStarted="StartUploadImg" 
    OnClientUploadComplete="UploadCompleteImg" />

<httpRuntime maxRequestLength = "1024000" 
executionTimeout="54000" 
enableHeaderChecking ="false" />

使用AngularJs + Web API,为什么我们需要ASP.NET MVC和IIS？

我可以使用AngularJS plus WEB API开发没有IIS和ASP.NET MVC的Web应用程序吗？

我正在研究从MS SQL数据库到POCO类的映射:

我有numeric(19, 0),numeric(18, 0),numeric(3, 0),numeric(3, 0).

我正在使用EF电源工具生成POCO并将所有映射到十进制.NET C# Type.

但我认为它应该映射到BigInt,Int64,Int32,Int16等.
