Geodatabase constructor hangs with organziation URL

KarlBeal — Tue, 01 Aug 2023 15:57:12 GMT

I created a feature layer in my ArcGIS Online organization. The URL looks like: https://services7.arcgis.com/<unique string>/arcgis/rest/services/Test_Feature_Layer/FeatureServer

If I sign out of the licensing portal in ArcGIS Pro and then run the code shown below with my URL, it will freeze at the constructor on line 9.

How can I avoid this frozen state?

public bool TestConnection(string url) { return RunMCTOnNonGUIThread(() => { Geodatabase gdb = null; try { var service = new ServiceConnectionProperties(new Uri(url)); gdb = new Geodatabase(service); return true; } catch { return false; } finally { gdb?.Dispose(); } }); } private T RunMCTOnNonGUIThread<T>(Func<T> function) => Task.Run(() => QueuedTask.Run(function)).Result;

try this: - Your utility method is likely causing a deadlock. u dont need the extra Task wrapper around the QueuedTask. Also, using Task.Result should be avoided (as it can cause deadlocks).

public Task<bool> TestConnectionAsync(string url) { return QueuedTask.Run(() => { try { var service = new ServiceConnectionProperties(new Uri(url)); using (var gdb = new Geodatabase(service)) return true; } catch { return false; } }); } //usage var connect_ok = await TestConnectionAsync("connection_string");

Thanks for the info. I am not going to be able to verify if this is the solution for a while.

Properly adding an async from our UI to this method would be a very difficult task.

Is there a way to check if I am currently signed into ArcGIS portal before attempting to call the Geodatabase constructor?

not from the UI. At some point u have to go onto the QueuedTask.

Once on the QueuedTask u can call ArcGISPortal IsSignedOn()
