[One .NET] Missing AndroidSdkSupportedTargetPlatformVersion values #6107
Description
The file Microsoft.Android.Sdk.SupportedPlatforms.targets should include <AndroidSdkSupportedTargetPlatformVersion> versions for every API level we support (21 - 30). However in Preview 6, it only includes 30:
<Project>
<PropertyGroup>
<TargetPlatformSupported>true</TargetPlatformSupported>
<TargetPlatformVersion Condition=" '$(TargetPlatformVersion)' == '' ">30.0</TargetPlatformVersion>
</PropertyGroup>
<ItemGroup>
<AndroidSdkSupportedTargetPlatformVersion Include="30.0" />
<SdkSupportedTargetPlatformVersion Include="@(AndroidSdkSupportedTargetPlatformVersion)" />
</ItemGroup>
</Project>This means a user cannot currently use eg: net6.0-android28.0 as a <TargetFramework>:
error NETSDK1140: 28.0 is not a valid TargetPlatformVersion for android. Valid versions include:
error NETSDK1140: 30.0
@jonathanpeppers says this is a regression and that it used to work.
