Create Extension just like ArcMap

I am developing an Pro application that will control edit events.

I would like to give option to turn of this option.

In ArcMap I would develop code that implement IExtension and IExtensioConfig then the extension "remember" if it is on or off. If it is on it runs the startup. If I am turning it off it will un subscribe to the events.

Here is the docs for ArcMap https://desktop.arcgis.com/en/arcobjects/latest/net/webframe.htm#AppFrameworkExtensionHowTo.htm

Moving to Pro I used this example: https://github.com/Esri/arcgis-pro-sdk-community-samples/tree/master/Framework/Licensing

I do not have a license for the extension.

I see two problems. First I do not see startup method - what code is running when extension exists?

Then the extension is always turned off, I could not find a way to remember the last state.

You can implement IExtensionConfig in your Module class and activate/deactivate your events in the State property setter:

public ExtensionState State { get { return this._state; } set { this._state = value; if (value == ExtensionState.Disabled) this.UnwireEvents(); else if (value == ExtensionState.Enabled) this.WireEvents(); } }

If you want to persist your extension state in the project, you can overwrite the OnReadSettingsAsync and OnWriteSettingsAsync methods:

protected override Task OnReadSettingsAsync(ModuleSettingsReader settings) { if (null == settings) return Task.FromResult(0); var value = settings.Get("MyExtensionState"); if (value != null && value is string s && Enum.TryParse(s, out ExtensionState extensionState)) { this.State = extensionState; } return Task.FromResult(0); } protected override Task OnWriteSettingsAsync(ModuleSettingsWriter settings) { settings.Add("MyExtensionState", this.State.ToString()); return Task.FromResult(0); }

See also https://github.com/Esri/arcgis-pro-sdk/wiki/ProGuide-Custom-settings. This also explains how to store settings at the application/user level.
