VijayAnand.MauiTemplates 3.2.0-preview.5

Project and Item Templates for developing .NET MAUI App that runs on Android, iOS, macOS, Windows, and Tizen

• All-in-One .NET MAUI App project template and is named as mauiapp
• .NET MAUI Class Library project template and is named as mauiclasslib
• Shared Class Library (Xamarin.Forms and .NET MAUI) project template and is named as sharedclasslib

Item templates for the following:

Item	Template Name
ContentPage (XAML)	maui-page
ContentPage (C#)	maui-page-cs
ContentPage (Razor)	maui-page-razor
ContentView (XAML)	maui-view
ContentView (C#)	maui-view-cs
ContentView (Razor)	maui-view-razor
ResourceDictionary (XAML)	maui-resdict
ShellPage (XAML)	maui-shell
ShellPage (C#)	maui-shell-cs
ShellPage (Razor)	maui-shell-razor
ContentPage (XAML) with ViewModel	maui-mvvm
ContentPage (C#) with ViewModel	maui-mvvm-cs
ContentPage with BlazorWebView (XAML)	maui-bwv
ContentPage with BlazorWebView (C#)	maui-bwv-cs
Partial Class (C#)	class-cs

All of these templates currently target .NET MAUI on .NET 6/7 GA and its Service Releases and .NET 8 Previews.

Install the template package from NuGet with the below command.

dotnet new install VijayAnand.MauiTemplates

If you've already installed this package, then this can be updated to the latest version with the below command.

dotnet new update --check-only

dotnet new update

Parameters:

Starting with v2.0.0 of the template package, to effectively support .NET MAUI on both .NET 6 and .NET 7, CLI project template defines a new parameter named framework:

Starting with v3.0.0 of the template package, CLI project template framework parameter adds .NET 8 as another option.

• Framework: (Short notation: -f)

  This can take net6.0 / net7.0 / net8.0 as its options (with net7.0 being the default value, if not provided).

  Examples:

  dotnet new mauiapp -f net6.0
  

  Below command can be simplified to dotnet new mauiapp as default value of framework parameter is net7.0

  dotnet new mauiapp -f net7.0
  

  For creating a .NET MAUI App on .NET 8 Preview:

  dotnet new mauiapp -f net8.0
  

In .NET CLI, all of these Item Templates takes two parameters:

• Name: (Short notation: -n)

  The name of the project/page/view to create. For pages/views, don't need to suffix it with .xaml, it will get added.

  If the name parameter is not specified, by default, the .NET CLI template engine will take the current folder name as the filename (current behaviour of the templating engine).

• Namespace: (Short notation: -na)

  The namespace for the generated files.

  While working with .NET 7 or higher SDK, the namespace parameter in short notation needs to be passed as -p:na (i.e., it needs to be prefixed with -p:).

• Now with more options while creating the app or class library project, ability to include NuGet packages on the fly for CommunityToolkit.Maui, CommunityToolkit.Maui.Markup, CommunityToolkit.Mvvm or all.

Note: Parameter values are case-insensitive.

Both .NET MAUI App and Class Library templates take the below optional Boolean parameters to include the officially supported CommunityToolkit NuGet packages:

Specifying the parameter name, either in short or full notation, implies that it is defined.

• -it | --include-toolkit - Default is false
• -im | --include-markup - Default is false
• -imt | --include-mvvm-toolkit - Default is false
• -cc | --conditional-compilation - Default is false

Conditional Compilation

And now conditional compilation can be configured so that platform source files can be defined anywhere in the project provided they follow a naming convention as mentioned below. This will allow maintaining related source files in the same place, especially MAUI Handlers.

• *.Standard.cs - Files targeting the BCL
• *.Android.cs - Files specific to Android
• *.iOS.cs - Files shared with both iOS and MacCatalyst
• *.MacCatalyst.cs - Files specific to MacCatalyst
• *.Tizen.cs - Files specific to Tizen
• *.Windows.cs - Files specific to Windows

For existing projects, add the below block of code in the project file (.csproj). This will modify the behavior of build process so due care must be taken if doing so.

<ItemGroup Condition="'$(TargetFramework)' != 'net6.0'">
    <Compile Remove="**\*.Standard.cs" />
    <None Include="**\*.Standard.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
</ItemGroup>

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'ios' AND $([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'maccatalyst'">
    <Compile Remove="**\*.iOS.cs" />
    <None Include="**\*.iOS.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
    <Compile Remove="**\iOS\**\*.cs" />
    <None Include="**\iOS\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
</ItemGroup>

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'android'">
    <Compile Remove="**\*.Android.cs" />
    <None Include="**\*.Android.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
    <Compile Remove="**\Android\**\*.cs" />
    <None Include="**\Android\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
</ItemGroup>

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'maccatalyst'">
    <Compile Remove="**\*.MacCatalyst.cs" />
    <None Include="**\*.MacCatalyst.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
    <Compile Remove="**\MacCatalyst\**\*.cs" />
    <None Include="**\MacCatalyst\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
</ItemGroup>

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'tizen'">
    <Compile Remove="**\*.Tizen.cs" />
    <None Include="**\*.Tizen.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
    <Compile Remove="**\Tizen\**\*.cs" />
    <None Include="**\Tizen\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
</ItemGroup>

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'windows'">
    <Compile Remove="**\*.Windows.cs" />
    <None Include="**\*.Windows.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />

</ItemGroup>

All-in-One .NET MAUI App Project Template:

This takes two additional parameters to define the application design pattern and target platform respectively:

• -dp | --design-pattern

Can take any one of the following values, with default value set to Plain:

Parameter Value	Description
Plain	App configured to work with a single, initial screen.
Hierarchical	App configured to work in a Hierarchical pattern using NavigationPage.
Tab	App configured to work in a Tabbed fashion using TabbedPage.
Shell	App configured to work with Routes using Shell page.
Hybrid	App configured to work in a Hybrid fashion using BlazorWebView.
Markup	App configured to work with C# Markup syntax.
Razor	App configured to work with Razor syntax.
Comet	App configured to work with MVU pattern using Comet.
Reactor	App configured to work with MVU pattern using Reactor.

• -tp | --target-platform

Can take a combination of the following values, with default value set to All:

Parameter Value	Description
All	Targets all possible .NET MAUI supported platforms.
Base	Targets base framework (.NET 6/7/8) based on the framework opted.
Android	Targets Android platform.
iOS	Targets iOS platform.
macOS	Targets macOS platform via Mac Catalyst.
Windows	Targets Windows platform.
Tizen	Targets Tizen platform.
Mobile	Targets Android and iOS platforms.
Desktop	Targets Windows and macOS platforms.
Apple	Targets iOS and macOS platforms.

Additional parameters supported:

MVVM is a delightful and development-friendly design pattern to work with. To support this, a new parameter has been introduced:

• -mvvm | --use-mvvm - Default is false
• -icb | --include-compiled-bindings - Default is false

Note: Opting for this MVVM option will not have any impact on the App created with Web-based Razor syntax or MVU based Comet/Reactor.

While creating a Blazor Hybrid App, an option to abstract the Razor components as a separate Razor class library.

• -rcl | --razor-class-library - Default is false

The target for the Windows platform can be either Package (MSIX) or Unpackaged. By default, it is set as Package, this can be overridden while creating the project by including the below parameter:

• -wu | --windows-unpackaged - Default is false

While targeting .NET 7 or later, an option to add and configure CommunityToolkit.Maui.MediaElement, Microsoft.Maui.Controls.Foldable, Microsoft.Maui.Controls.Maps, or all NuGet packages.

• -ime | --include-media-element - Default is false
• -if | --include-foldable - Default is false
• -inm | --include-maps - Default is false

Note: If the project target .NET 6, selecting the MediaElement/Foldable/Maps option will NOT have any impact.

Examples:

dotnet new mauiapp --design-pattern Hybrid --target-platform Mobile

dotnet new mauiapp -dp Shell -tp Android

.NET MAUI Class Library Project Template:

Similar to All-in-One .NET MAUI App, the Class Library project template also takes target-platform as a parameter that takes a combination from the same set of values (with All being the default value).

  • Parameter name: --use-razor-sdk | -usr
• Can be created targeting .NET MAUI Core
  • Parameter name: --use-maui-core | -umc
• Can be created targeting .NET MAUI Essentials
  • Parameter name: --use-maui-essentials | -ume

Shared Class Library Project Template:

This takes the below optional Boolean parameters to include the officially supported NuGet packages:

Specifying the parameter name, either in short or full notation, implies that it is defined.

Single parameter to include all the supported NuGet packages:

• -asp | --all-supported-packages - Default is false

Specific to Xamarin.Forms:

• -ife | --include-forms-essentials - Default is false
• -ift | --include-forms-toolkit - Default is false
• -ifm | --include-forms-markup - Default is false

Specific to .NET MAUI:
