Hi @anass.yazane.1

Can you provide the version of the Refinitiv Data Library for .Net? In the latest versions, there is no longer a "DeployedSession", but rather the functionality has been included within the "PlatformSession".

For example:

var deployedSession = PlatformSession.Definition().Host("ATSserver:15000")
                                                  .GetSession();
deployedSession.Open();

If you are running into DACs issues when creating a deployed session that requires DACs parameters, please look at this example. If you continue having issues connecting into your deployed ADS, you will need to contact the market data administrators to determine if you have the ability to access this server and what your DACs parameters should be.

"is there a way to tell to the process that Platformsession opened, as it will be running on PC with Eikon running, should not interrupt quotes and others processus runned uding eikon desktop."

Can you please elaborate this statement?

One thing you need to be aware of is when you create multiple sessions, you should specify the explicit session when making requests for data. For example, if you want to retrieve market data from the above deployed Session, it would look something like this:

var stream = Pricing.Definition().Universe("EUR=")
                                 .GetStream(deployedSession).OnRefresh(...)
                                                            .OnUpdate(...)
                                                            .OnStatus(...);
stream.Open();

And if you create a desktop session to retrieve historical pricing for example:

var response = Summaries.Definition("AAPL.O").GetData(desktopSession);
