Is it possible to create platform specific views?

Question

In UWP, device specific views can be created by placing those views into their respective folders or appending the relevant device name to the file name. I don't see any information on doing the equivalent with MAUI as regards platform specific views only platform specific code. Is this a thing ?

The closest I can get is using preprocessor directives and giving the files unique names. This means there are still multiple code behind files unfortunately.

So -

#if ANDROID

      await Navigation.PushAsync(new Page1Windows());
 

#elif WINDOWS

      await Navigation.PushAsync(new Page1Android());
    

#endif

It's a thing. The default MAUI projects provide a platform specific folder you can put platform specific code in.

If you want something more complicated, like your platform-named folders or files, you can edit your csproj to include or exclude files by name & platform.

There are examples of both file and folder-based targeting in the Configure multi-targeting docs:

Here's the combined view from Combine filename and folder multi-targeting that excludes files and folders that include platform names that don't match the current target.

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

<ItemGroup Condition="$(TargetFramework.StartsWith('net6.0-ios')) != true AND $(TargetFramework.StartsWith('net6.0-maccatalyst')) != true"> 
   <Compile Remove="**\**\*.iOS.cs" />   <None Include="**\**\*.iOS.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />  
   <Compile Remove="**\iOS\**\*.cs" />   <None Include="**\iOS\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />  
</ItemGroup>

<ItemGroup Condition="$(TargetFramework.Contains('-windows')) != true ">
    <Compile Remove="**\*.Windows.cs" />   <None Include="**\*.Windows.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" />
    <Compile Remove="**\Windows\**\*.cs" />   <None Include="**\Windows\**\*.cs" Exclude="$(DefaultItemExcludes);$(DefaultExcludesInProjectFolder)" /> 
</ItemGroup>
