Manually executing a command in ReactiveUI 7.2

Question

I'm trying to execute a command so that a function I have runs asynchronously in from within the constructor of my view. I understand that running something asynchronously in a constructor isn't necessarily good practice, but I need to load a datagrid when the view opens which takes anywhere from 3-5 seconds, so I thought I could load a progress bar with an IsLoading property while my command to fetch the data runs on a separate thread.

Here is my command / property declaration to do the above:

public ReactiveCommand EnterCmd { get; private set; }
ObservableAsPropertyHelper<bool> _isLoading;
public bool IsLoading => _isLoading.Value;

And here are my instantiations in the constructor:

EnterCmd = ReactiveCommand.CreateFromTask(LoadGridData);
EnterCmd.IsExecuting.ToProperty(this, x => x.IsLoading, out _isLoading);

I'd like to run start my command by doing something like EnterCmd.Execute(). It's worth noting that I did find a similar question here, but Execute() doesn't seem to be a valid method on a ReactiveCommand anymore. Any ideas would be appreciated.

The Exexute() method was changed in version 7. It now returns an observable, so you need to subscribe to it for it to work:

EnterCmd.Execute().Subscribe();
