reduce the size of a unpacked Winui 3 application

I have a WinUi 3 (c#)solution that contains 3 projects: A, B, C.

A: main application(exe) depends on B,C.

B: dll project depends on C.

c: dll project.

Now I like to build the solution as a unpacked application and pack it into a wix installer, so I want to reduce the file number of unpacked application as much as I can.

I added following property in project file of A for building.

<WindowsPackageType>None</WindowsPackageType>

Here is the output folder after building:

B.dll
B.pri
A.deps.json
A.dll
A.exe
A.pri
A.runtimeconfig.json
C.dll
C.pri
WinUI.Icon.dll
WinUI.Token.dll
Microsoft.Extensions.DependencyInjection.Abstractions.dll
Microsoft.Extensions.DependencyInjection.dll
Microsoft.InteractiveExperiences.Projection.dll
Microsoft.Windows.ApplicationModel.DynamicDependency.Projection.dll
Microsoft.Windows.ApplicationModel.Resources.Projection.dll
Microsoft.Windows.ApplicationModel.WindowsAppRuntime.Projection.dll
Microsoft.Windows.AppLifecycle.Projection.dll
Microsoft.Windows.AppNotifications.Builder.Projection.dll
Microsoft.Windows.AppNotifications.Projection.dll
Microsoft.Windows.PushNotifications.Projection.dll
Microsoft.Windows.SDK.NET.dll
Microsoft.Windows.Security.AccessControl.Projection.dll
Microsoft.Windows.System.Power.Projection.dll
Microsoft.Windows.System.Projection.dll
Microsoft.Windows.Widgets.Providers.Projection.dll
Microsoft.WindowsAppRuntime.Bootstrap.Net.dll
Microsoft.WinUI.dll
Microsoft.Xaml.Interactions.dll
Microsoft.Xaml.Interactivity.dll
WinRT.Runtime.dll
CommunityToolkit.Mvvm.dll
Removed   // put unneeded files in this folder  
runtimes  // folder contains win10-x64\native\Microsoft.WindowsAppRuntime.Bootstrap.dll
Assets    // contains the jpg and icon files referenced by application.

Here are the files I put in the "Removed" folder cause the application can be launched without them.

  1. all language folders like "xx-xx";
  2. .xaml and .xbf files.
  3. pdb files and unneeded runtime folder like "win10-arm64:

Question:

Is this the best I can do? Is it possible to remove following files or folder?

  1. A.deps.json and A.runtimeconfig.json.
  2. "Assets" folder
  3. pri files.

currently this is not possible, but mybe you can use vs post-build event for removing languages folder, however if you want to reduce your app size, best option is to use Trimming https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/trim-self-contained
