xamarin.forms

The specified language targets for MonoAndroid90 is missing. Ensure correct tooling is installed for 'MonoAndroid'

When trying to build an older Xamarin Forms project in Visual Studio 2019, I get the following error:

The specified language targets for MonoAndroid90 is missing. Ensure correct tooling is installed for 'MonoAndroid'. Missing: 'C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.CSharp.targets'    MediaManager    C:\Users\...\.nuget\packages\msbuild.sdk.extras\2.0.24\Build\LanguageTargets\CheckMissing.targets   36

I have the following SDK items installed.

Solution

  • Modify the first line of the csproj file from

    <Project Sdk="MSBuild.Sdk.Extras">

    to the line below

    <Project Sdk="MSBuild.Sdk.Extras/3.0.22">

    3.0.22 was the current version of the MSBuild.Sdk.Extras Nuget package.

    I also restarted VS, cleaned the project, etc. along the way.
