Issues getting .Net Maui to work in Linux!

Other Extensions

After fixing the stuff below I still had issues building and running from VS Code.

It turns out that the ESP-IDF extension was causing issues (I'd noticed it being annoying in general C# projects) and things started working when I'd disabled it.

General

In VS Code check the Output tab in the Terminal section to see troubleshooting tips on your installation.

Can't find Android SDK

This is constantly happening; despite being an issue on github.

Setting the following helps.

export ANDROID_SDK_ROOT=$ANDROID_HOME

iOS and Mac Frameworks on Linux

Default (even now - there are issues going back two years on this) is to try and build iOS / Mac on LInux.

For now you need to set the TargetFrameworks elements in the csporj file as follows (move the ios/mac entries from the default into a conditional element):

<TargetFrameworks>net9.0-android</TargetFrameworks>
        <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net9.0-windows10.0.19041.0</TargetFrameworks>
        <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('OSX'))">$(TargetFrameworks);net9.0-ios;net9.0-maccatalyst</TargetFrameworks>

Android SDK Setup

The Android SDK command line tools are needed (tick in the Android Studio SDK Tools setup tab)

Android Emulator

VS Code seems to want the latest version of the Google API installed. The output window will give you the command line to install it.

✓ emulator - INSTALLED (version '35.4.9')
✗ system-images/android-35/google_apis/x86_64 - NOT INSTALLED (Required for default platform)
✓ system-images/android-34/google_apis/x86_64 - INSTALLED (version '14')

JDK Version

At the time of writing Maui insists on JDK 17.

 

sudo apt install openjdk-17-jdk
