我有一个简单的Web服务调用,由.NET(C#)2.0 Windows应用程序通过Visual Studio生成的Web服务代理生成,用于也用C#(2.0)编写的Web服务.这已经工作了几年,并且在它运行的十几个地方继续这样做.

新站点的新安装遇到问题.尝试调用Web服务时,它失败并显示以下消息:

无法为SSL/TLS安全通道建立信任关系

Web服务的URL使用SSL(https://) - 但这已经在很多其他位置工作了很长时间(并且仍在继续).

我在哪里看？这可能是Windows和.NET之间的安全问题吗？如果是这样,我在哪里建立信任关系？我迷路了!

我收到这个错误:

根据验证程序,远程证书无效.

每当我尝试使用我的C#代码中的Gmail SMTP服务器发送电子邮件时.有人能指出我找到解决这个问题的正确方向吗？

我正在尝试使用Fiddler来帮助某人解决Invoke-RestMethod调用ASP.NET WebAPI的问题.不幸的是,当我Invoke-RestMethod在PowerShell中调用时,Fiddler并没有拦截HTTP通信.

当我使用Internet Explorer浏览作为同一应用程序一部分的ASP.NET网站的根目录时,Fiddler会按预期拦截流量.

任何人都可以解释为什么Fiddler没有通过PowerShell捕获HTTP流量,以及如何解决这个问题？

我正在尝试使用C#让RabbitMQ 3.6.2在Windows 7上针对Erlang 18.0使用SSL/TLS.当我在C#代码中启用SSL时,我遇到了错误.我已经通过建立SSL/TLS的步骤了这里.我也经历了[故障排除步骤] [2],显示出成功(除了由于缺乏对stunnel的了解而无法完成stunnel步骤).这是我的C#代码试图连接到RabbitMQ:

var factory = new ConnectionFactory()
{
    // NOTE: guest username ONLY works with HostName "localhost"!
    //HostName = Environment.MachineName,
    HostName = "localhost",
    UserName = "guest",
    Password = "guest",
};

// Without this line, RabbitMQ.log shows error: "SSL: hello: tls_handshake.erl:174:Fatal error: protocol version"
// When I add this line to go to TLS 1.2, .NET throws an exception: The remote certificate is invalid according to the validation procedure.

每次我尝试通过 VS2015 和 IIS Express 在我的开发盒上运行我的 MVC 项目时，我都会收到一个错误。它使用此代码对我们的 ADFS 服务器进行身份验证。

app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
            app.UseCookieAuthentication(new CookieAuthenticationOptions());

            app.UseWsFederationAuthentication(
                new WsFederationAuthenticationOptions
                {
                    Wtrealm = realm,
                    MetadataAddress = adfsMetadata
                });

这是我在浏览器中遇到的错误。
