Hello
We are integrating your dll (HTTPS component) with our soluction and we have found some troubles with the communication that we can't understand.

Our application is developed in .NET with C# in Visual Studio 2005 as device application with Operation System Windows Embebed 5. (For Device Pidion 1300).

We are trying to send any times information to httpsRequest and the two first times it wort fine but when the second call is send the log said: "closing TLS socket" and it cant send more.

I put the log here.

Thank you.

The System.Net.Sockets.SocketException: A socket operation encountered a dead network is typically caused by unreliable network connection. This is common problem on .NET CF when using dial up connection.

This problem has typically nothing to do with Rebex components. If you use plain system socket, you will encounter the same issue.

This is what we recommend to our users, who use dial up connection:

To connect using a dial up connection from .NET CF on Windows Mobile, you can use Connection Manager functions such as ConnMgrEnumDestinations, ConnMgrEstablishConnection and ConnMgrReleaseConnection. Check out https://msdn.microsoft.com/en-us/library/bb840031.aspx for details. There are no classes available for this in .NET CF, but it can be done quite easily using P/Invoke if you have some experience with this.

But perhaps a better choice is to use the excelent Smart Device Framework by OpenNETCF that contains a wrapper class for the Connection Manager that is extremely easy to use:
https://github.com/ctacke/sdf/tree/master/OpenNETCF.Net/OpenNETCF.Net
It is open source project, so you might either use it as is or as a reference for your own implementation if you prefer.
