H.Uno.Sdk.Manifest 0.25.0

Uno.Sdk

Single project solution for Uno. Supported platforms:

• Mobile(iOS, macOS, MacCatalyst and Android)(net8.0-maccatalyst;net8.0-android;net8.0-ios;net8.0-macos)

Usage

Here are three possible uses:

• Use local SDK after installing workload (Recommended)

<Project Sdk="H.Uno.Sdk">

    <PropertyGroup>
        <TargetFrameworks>net8.0-maccatalyst;net8.0-android;net8.0-ios;net8.0-webassembly;net8.0-gtk;net8.0-linux;net8.0-windows</TargetFrameworks>
        <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net8.0-windows10.0.19041.0</TargetFrameworks>
    </PropertyGroup>

</Project>

• Use SDK via NuGet. A small hack will be used here to disable the error message about missing workloads for webassembly/linux/gtk.

<Project Sdk="H.Uno.Sdk/0.25.0">

    <PropertyGroup>
        <TargetFrameworks>net8.0-maccatalyst;net8.0-android;net8.0-ios;net8.0-webassembly;net8.0-gtk;net8.0-linux;net8.0-windows</TargetFrameworks>
        <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net8.0-windows10.0.19041.0</TargetFrameworks>
    </PropertyGroup>

</Project>

Note: To restore correctly from NuGet you need to run this in a project where net8.0-webassembly;net8.0-gtk;net8.0-linux is missing

• Use via Microsoft.NET.Sdk and <UseUno>true</UseUno> after installing the workload (the most correct, but currently not supported due to the fact that WebAssembly requires Microsoft.NET.Sdk.Web which will not work with some target frameworks)

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

    <PropertyGroup>
        <TargetFrameworks>net8.0-maccatalyst;net8.0-android;net8.0-ios;net8.0-webassembly;net8.0-gtk;net8.0-linux;net8.0-windows</TargetFrameworks>
        <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net8.0-windows10.0.19041.0</TargetFrameworks>
        <UseUno>true</UseUno> 
    </PropertyGroup>

</Project>

Fast start

You can use https://github.com/HavenDV/Uno.Sdk.Example/ as a start point or just use templates:

dotnet new install H.Uno.Templates # If you don't have installed workload
mkdir SingleProjectSolution
cd SingleProjectSolution
dotnet new uno
dotnet build
dotnet run --framework net8.0-gtk

Install workload

Although you don't have to do this for NuGet way, full support for the custom target frameworks requires installing the appropriate workload:

• On Linux / macOS:

curl -sSL https://raw.githubusercontent.com/HavenDV/Uno.Sdk/main/scripts/workload-install.sh | sudo bash

• On Windows:

Invoke-WebRequest 'https://raw.githubusercontent.com/HavenDV/Uno.Sdk/main/scripts/workload-install.ps1' -OutFile 'workload-install.ps1';
./workload-install.ps1

Uninstall

dotnet workload uninstall uno

Settings

The SDK is designed to assign default values only to properties that have not been explicitly set by the user. This way the user has full control over what the SDK does. Settings:

• <UseUnoUwp>true</UseUnoUwp> - will use Uno.UI packages instead of Uno.WinUI.
• <UnoVersion>5.0.0</UnoVersion (and other versions, see here) - will change the versions of all implicit PackageReferences

Disclaimer

Although this is a working solution, I have simplified some things regarding workload and manifest, which could theoretically cause problems (for example, when upgrading to a new sdk version).

Cons

• Allows you to use [UnsupportedOSPlatform("gtk") attributes, which will replace the custom generator and custom attributes for unsupported methods
