Extensions.Hosting.Wpf.Threading 2.0.0

Microsoft.Extensions.Hosting.Wpf.Threading

Extension library for Microsoft.Extensions.Hosting.Wpf. This adds support to switch to Main UI Thread or ThreadPool Thread with the help of Microsoft.VisualStudio.Threading.

This can be really useful when using WPF inside Microsoft.Extensions.Hosting since sometimes you might need to show UI from not UI thread, for example during some network request.

Getting Started

Install nuget

Install-Package Extensions.Hosting.Wpf

Register service

private static void ConfigureServices(HostBuilderContext hostContext, IServiceCollection services)
{
    services.AddWpf<App>();
    services.AddThreadSwitching<App>(); //<--- new line
}

Example Usage

private readonly JoinableTaskFactory _joinableTaskFactory;

public SomeConstructor(JoinableTaskFactory joinableTaskFactory)
{
    _joinableTaskFactory = joinableTaskFactory
}

private async Task SomeOperationAsync() {
    // on the caller's thread.
    await DoAsync();

    // Now switch to a threadpool thread explicitly.
    await TaskScheduler.Default;

    // Now switch to the Main thread to talk to some STA object.
    await _joinableTaskFactory.SwitchToMainThreadAsync();
    STAService.DoSomething();
}
