API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)
App capabilities	ID_CAP_NETWORKING [Windows Phone]

Fields

AddressAlreadyInUse	10	The address is already in use.
AddressFamilyNotSupported	4	The address family is not supported.
CannotAssignRequestedAddress	11	Cannot assign requested address.
CertificateCommonNameIsIncorrect	25	The certificate is not valid for the requested usage. This error is also returned if the certificate has an invalid name. The name is not included in the permitted list or is explicitly excluded.
CertificateExpired	23	A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. This error is also returned if the validity periods of the certification chain do not nest correctly.
CertificateIsInvalid	30	The supplied certificate is invalid. This can be returned for a number of reasons: A certificate that can only be used as an end-entity is being used as a CA or vice versa. A path length constraint in the certification chain has been violated. A certificate contains an unknown extension that is marked critical. A certificate is being used for a purpose other than the ones specified by its CA. A parent of a given certificate in fact did not issue that child certificate. A certificate is missing or has an empty value for an important field, such as a subject or issuer name. The signature of the certificate cannot be verified. The certificate has an invalid policy. A certificate's basic constraint extension has not been observed.
CertificateNoRevocationCheck	28	The revocation function was unable to check revocation for the certificate.
CertificateRevocationServerOffline	29	The revocation function was unable to check revocation because the revocation server was offline.
CertificateRevoked	27	A certificate was explicitly revoked by its issuer. This error is also returned if the certificate was explicitly marked as untrusted by the user.
CertificateUntrustedRoot	24	A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. This error is also returned if a certificate chain could not be built to a trusted root authority.
CertificateWrongUsage	26	The certificate is not valid for the requested usage.
ClassTypeNotFound	9	The specified class was not found.
ConnectionRefused	12	The connection was refused.
ConnectionResetByPeer	18	The connection was reset by the peer.
ConnectionTimedOut	3	A connection timeout was exceeded.
HostIsDown	19	The host is down.
HostNotFound	6	The host was not found.
HttpInvalidServerResponse	2	A bad response was received from the HTTP server.
MessageTooLong	22	A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the datagram itself.
NetworkDroppedConnectionOnReset	16	The network dropped connection on reset.
NetworkIsDown	15	The network is down.
NetworkIsUnreachable	13	The network is unreachable.
NoAddressesFound	20	The pipe is being closed.
NoDataRecordOfRequestedType	7	The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for.
NonAuthoritativeHostNotFound	8	This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server.
OperationAborted	1	The operation was aborted.
SocketTypeNotSupported	5	The socket type is not supported.
SoftwareCausedConnectionAbort	17	Software caused a connection abort.
TooManyOpenFiles	21	Too many open files.
Unknown	0	The socket status is unknown.
UnreachableHost	14	The host is unreachable.

Remarks

An error encountered on socket operation is returned as HRESULT value. The SocketError.GetStatus method is used to convert an error from a socket operation to a SocketErrorStatus enumeration value. Most of the SocketErrorStatus enumeration values correspond to an error returned by the native Windows sockets operation.
