Reference Windows only project from NET MAUI-CodePudding

I have been working on tool that is done using NET MAUI. Now I would like to automate Windows UI, but I can't figure out how to do that. I have tried to download FlaUI NuGet, but can't get it working as it requires project to be Net7.0-windows. So I have created new project with reference to Net7.0-windows, but then my references in Net Maui get corrupted.

MauiApp1.csproj (project):

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

    <PropertyGroup>
        <TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>

Currently if:

I get following errors:

My question is How to reference ClassLibrary1.csproj in MauiApp1.csproj in NET MAUI? Is there some way to get this setup working?

CodePudding user response：

I know little about FlaUI, but removing this line in MauiApp1.csproj might work:

<TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>

CodePudding user response：

If your ClassLibrary1 project going to support all platforms then you should add this lines to your ClassLibrary1.cspoj file too.

<TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>
<TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.19041.0</TargetFrameworks>

If your ClassLibrary1 project going to support just windows then you can do two things;

If your MAUI project just going to run on windows only, on your MauiApp1.csproj file you should delete this line;

<TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>

and these lines;

<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">11.0</SupportedOSPlatformVersion>
<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">13.1</SupportedOSPlatformVersion>
<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">21.0</SupportedOSPlatformVersion>
<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tizen'">6.5</SupportedOSPlatformVersion>

If your MAUI App going to support other platforms at the same time you should add your platform specific libraries separate. I am using this for my multiplatform MAUI apps.
