VijayAnand.MauiTemplates 2.1.2

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

• All-in-One project template for .NET MAUI App 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:

All of these templates currently target .NET MAUI on .NET 7 GA, stable release as of Nov 2022.

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 templates defines a new parameter named framework:

• Framework: (Short notation: -f)

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

  Examples:

  dotnet new mauiapp --framework 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
  

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 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

Additional parameters for App project:

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, an option to add and configure Microsoft.Maui.Controls.Foldable, Microsoft.Maui.Controls.Maps, or both NuGet packages.

• -if | --include-foldable - Default is false
• -inm | --include-maps - Default is false

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

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)" />
    <Compile Remove="**\Windows\**\*.cs" />
    <None Include="**\Windows\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
</ItemGroup>

All-in-One .NET MAUI App project 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:

• -tp | --target-platform

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

Examples:

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

dotnet new mauiapp -dp Shell -tp Android

Shared Class Library template take 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.
