ConvMVVM (Convergence MVVM) is free MVVM library for WPF inspired by Community Toolkit library and Prism frameworks.
- Visual Studio 2022
- Microsoft .NET 7
var collection = ConvMVVM.Core.DI.ServiceCollection.Create();
//it suport constructor injection
collection.RegisterCache<AModel>();
collection.RegisterCache<IBModel, BModel>();
//it support lambda creation
collection.RegisterCache<CModel>((container) =>{
var aModel = container.GetService<AModel>();
var bModel = container.GetService<IBModel>();
var model = CModel(aModel, bModel);
return model;
})
collection.RegisterCache<DModel>(new DModel());
//ioc container creation
var container = collection.CreateContainer();
var aModel1 = container.GetService<AModel>();
var bModel1 = container.GetService<IBModel>();
var dModel = container.GetService<DModel>();it support constructor injection and lambda creation routine
partial class AViewModel : NotifyObject
{
public AViewModel() {
}
//it support code generator
[Property]
private string _Test1 = "";
private string _Test2 = "";
public string Test2
{
get => _Test2;
set => Property(ref _Test2, value);
}
}it support property changed notification and source generator for property
partial class MainWindowViewModel : NotifyObject
{
public MainWindowViewModel() {
}
[RelayCommand]
private void Test()
{
System.Diagnostics.Debug.WriteLine("no delay!!");
}
[AsyncRelayCommand]
private async Task AsyncTest()
{
await Task.Delay(10000);
System.Diagnostics.Debug.WriteLine("delay!!");
}
}it support RelayCommand and AsyncRelayCommand also support source generator for them
