MvvmAIO.Prism.Bcl.Commands

Prism 8 companion library that provides AsyncDelegateCommand, AsyncDelegateCommand<T>, and IAsyncCommand for apps using Prism.Core 8.1.97 together with MvvmAIO.Prism.SourceGenerators.

Prism 9+ already ships these types — you do not need this package if you're on Prism 9 or later.

When Do You Need This?

Scenario Need this package?
Prism.Core 8.1.97 + [AsyncDelegateCommand] source generator Yes
Prism.Core 8.1.97 + hand-written AsyncDelegateCommand Yes
Prism 9.0+ (any usage) No — types already included
Only using synchronous [DelegateCommand] on Prism 8 No

Without this package on Prism 8, the analyzer reports PSG3002 — AsyncDelegateCommand type not found.

Installation

<PackageReference Include="MvvmAIO.Prism.Bcl.Commands" Version="0.3.1" />

Or:

dotnet add package MvvmAIO.Prism.Bcl.Commands

You also need MvvmAIO.Prism.SourceGenerators for the Roslyn generators and attribute definitions.

What's Included

Type Description
AsyncDelegateCommand Non-generic async command with Func<Task> / Func<CancellationToken, Task>
AsyncDelegateCommand<T> Generic async command with Func<T, Task> / Func<T, CancellationToken, Task>
IAsyncCommand Async command abstraction (ExecuteAsync with optional CancellationToken)

Fluent API

Both AsyncDelegateCommand and AsyncDelegateCommand<T> support Prism 9–style fluent chaining:

[AsyncDelegateCommand(
    CanExecute = nameof(CanSave),
    EnableParallelExecution = true,
    Catch = nameof(HandleError))]
private async Task SaveAsync(CancellationToken ct)
{
    await _repository.SaveAsync(ct);
}

private bool CanSave() => IsValid;
private void HandleError(Exception ex) => Logger.Error(ex);

Available fluent methods:

  • .EnableParallelExecution() — allow concurrent executions
  • .CancelAfter(TimeSpan) — auto-cancel after timeout
  • .CancellationTokenSourceFactory(Func<CancellationToken>) — custom token source
  • .Catch(Action<Exception>) / .Catch<TException>(Action<TException>) — error handling
  • .ObservesProperty(() => Property) — re-evaluate CanExecute on property change
  • .ObservesCanExecute(() => BoolProperty) — bind CanExecute to a boolean property
