ViewBaseGenerator 1.7.2

ViewBaseGenerator

The main purpose of the generator is to avoid boilerplate code in the code-behind views files, like this:

public abstract partial class PreviewDropViewBase
: ReactiveUI.Uno.ReactiveUserControl<Ratbuddyssey.ViewModels.PreviewDropViewModel>
{
}

public partial class MainView
{
    public MainView()
    {
        InitializeComponent();

        _ = this.WhenActivated(disposables =>
        {
            DataContext = ViewModel;
        });
    }
}

At the same time, the generator supports the ability to add your code anywhere through the definition of partial methods for special cases:

public partial class MainView
{
    partial void BeforeInitializeComponent();
    partial void AfterInitializeComponent();

    partial void AfterWhenActivated(CompositeDisposable disposables);

    public MainView()
    {
        BeforeInitializeComponent();

        InitializeComponent();

        AfterInitializeComponent();

        _ = this.WhenActivated(disposables =>
        {
            DataContext = ViewModel;

            if (ViewModel == null)
            {
                return;
            }

            AfterWhenActivated(disposables);
        });
    }
}

I also recommend not deleting .xaml.cs files, but leaving them empty like this:

namespace YourNamespace.Views;

public partial class MainView
{
}

Nuget

Install-Package ViewBaseGenerator

WPF/UWP/WinUI

  <PropertyGroup>
    <ViewBaseGenerator_Namespace>YourNamespace.Views</ViewBaseGenerator_Namespace>
  </PropertyGroup

  <ItemGroup Label="View Constructors">
    <AdditionalFiles Include="Views\**\*.xaml" ViewBaseGenerator_GenerateConstructor="True" ViewBaseGenerator_SetReactiveUIDataContext="True" />
  </ItemGroup>

  <ItemGroup Label="ViewBase">
    <AdditionalFiles Include="Views\**\*.xaml.cs" ViewBaseGenerator_BaseClass="ReactiveUI.Uno.ReactiveUserControl" ViewBaseGenerator_ViewModelNamespace="YourNamespace.ViewModels" />
  </ItemGroup>

Although ReactiveUI is supported, you can also use the generator without it, just to get rid of the InitializeComponent() constructors. In this case, you need code like:

  <PropertyGroup>
    <ViewBaseGenerator_Namespace>YourNamespace.Views</ViewBaseGenerator_Namespace>
  </PropertyGroup

  <ItemGroup Label="View Constructors">
    <AdditionalFiles Include="Views\**\*.xaml" ViewBaseGenerator_GenerateConstructor="True" />
  </ItemGroup>

Uno (projects besides UWP/WinUI)

Uno uses Source Generators and there is currently no way to use the output of one generator in another. Therefore, the solution is somewhat more complicated:

1. Create new project like this:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFrameworks>netstandard2.0;net6.0-android;net6.0-ios;net6.0-macos;net6.0-maccatalyst</TargetFrameworks>
  </PropertyGroup>

  <PropertyGroup>
    <ViewBaseGenerator_Namespace>YourNamespace.Views</ViewBaseGenerator_Namespace>
  </PropertyGroup>

  <ItemGroup Label="ViewBase">
    <AdditionalFiles Include="..\..\shared\YourNamespace.Shared\Views\**\*.xaml.cs" ViewBaseGenerator_BaseClass="ReactiveUI.Uno.ReactiveUserControl" ViewBaseGenerator_ViewModelNamespace="YourNamespace.ViewModels" Visible="False" />
    <AdditionalFiles Remove="..\..\shared\YourNamespace.Shared\Views\Navigation\MainView.xaml.cs" />
    <AdditionalFiles Include="..\..\shared\YourNamespace.Shared\Views\Navigation\MainView.xaml.cs" ViewBaseGenerator_BaseClass="ReactiveUI.Uno.ReactivePage" ViewBaseGenerator_ViewModelNamespace="YourNamespace.ViewModels" Visible="False" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="ViewBaseGenerator" Version="1.3.8">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

  <ItemGroup>
    
    <PackageReference Include="ReactiveUI.Uno" Version="16.2.6" />
  </ItemGroup>

  <ItemGroup>
    
    <ProjectReference Include="..\YourNamespace.Core\YourNamespace.Core.csproj" />
  </ItemGroup>
	
</Project>

2. Add this project reference to your apps.
