Our app crashed due to the unhandled exception. Seems like the exception occurred here:

WebSocket4Net/WebSocket4Net/WebSocket.cs

Line 429 in 042ff27

ProtocolProcessor.SendHandshake(this);

#80 have the similar issue and a simple exception handling might work just like it did here:

WebSocket4Net/WebSocket4Net/WebSocket.cs

Lines 629 to 639 in 042ff27

	try
	{
	ProtocolProcessor.SendCloseHandshake(this, statusCode, reason);
	}
	catch (Exception e)
	{
	if (Client != null)
	{
	OnError(e);
	}
	}

As the new 1.x.x version didn't support .NET framework, a fix on this version would be great:)
