Hello Laurentiu,

C# cannot be used to display the popup directly. What can be done is send a websocket message to the client side and display the popup when a websocket message is received. Like described here, but in the onNewMessage method you need to call this.showInformationDialog method (just check how it's called out-of-the-box) and pass the message to it.

If this is a local system you can use debugging with your C# code, see https://academy.creatio.com/docs/8.x/dev/development-on-creatio-platfor…

If this is a cloud system, sending messages to the UI to display a message box isn't the best route since the message boxes aren't blocking, meaning if your code sends 3 messages, only the last one will show in the message box, plus it means you have to add client-side code to receive the message and display it. 

It would be far better to just create a lookup object to write your debug messages to, then you just check the lookup to see the messages.

Ryan Farley,

Do you have an example how to write into a lookup  object please ?

You can write to any object using the following: 

var schema = UserConnection.EntitySchemaManager.GetInstanceByName("AccountType");
var entity = schema.CreateEntity(UserConnection)
entity.SetDefColumnValues();
entity.SetColumnValue("Name", "Some new type");
entity.Save();

However, for debugging, even better than writing to an object would be to use logging, see https://customerfx.com/article/logging-information-and-errors-in-creatio-c-code-and-viewing-from-cloud-hosted-systems/
