ArcGIS Pro 2.7 API Reference Guide
Geodatabase Constructor(ServiceConnectionProperties)
Example 

ArcGIS.Core.Data Namespace > Geodatabase Class > Geodatabase Constructor : Geodatabase Constructor(ServiceConnectionProperties)
A valid ServiceConnectionProperties object which has the URI to the feature service set. In case of feature services hosted on ArcGIS Server which is not federated with ArcGIS Portal, the username and password properties are also expected to be set.
Opens a web geodatabase given a serviceConnectionProperties to a valid feature service location. This method must be called on the MCT. Use QueuedTask.Run.
Syntax

Parameters

serviceConnectionProperties
A valid ServiceConnectionProperties object which has the URI to the feature service set. In case of feature services hosted on ArcGIS Server which is not federated with ArcGIS Portal, the username and password properties are also expected to be set.
Exceptions
ExceptionDescription
The serviceConnectionProperties to the feature service are invalid or if the feature service could not be opened.
This object must be created within the lambda or delegate passed to QueuedTask.Run, or on a compatible STA thread.
