Security Windows Phone 7上的TLS-在Bouncy Castle中发送客户端证书

我使用Bouncy Castle向WindowsPhone7上的服务器发送客户端证书时遇到问题

我创建了自己的TlsAuthentication和从接口继承的TlsCredential类。但在方法上

public TlsCredentials GetClientCredentials(CertificateRequest certificateRequest)
    {
        return this.TlsCredentials;
    }

出现异常

以下是我的例外：

An exception of type 'Org.BouncyCastle.Crypto.Tls.TlsFatalAlert' occurred in bouncywp71.DLL and wasn't handled before a managed/native boundary

A first chance exception of type 'System.IO.IOException' occurred in bouncywp71.DLL

An exception of type 'System.IO.IOException' occurred in bouncywp71.DLL and wasn't handled before a managed/native boundary

如果有人知道如何解决这个问题，请帮助我
