DotNet MAUI Blazor App build with razor class library (Android/iOS)

Question

Certificate configured as per the guide-line. We are able to generate build without razor class library. When we try to generate build with razor class getting below error.

dotnet\sdk\6.0.400-preview.22301.10\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResoluti
on.targets(267,5): error NETSDK1005: Assets file '\Razo
rClassLibrary\obj\project.assets.json' doesn't have a target for 'net6.0-android'. Ensure that restore has run and that
 you have included 'net6.0-android' in the TargetFrameworks for your project. [C:/RazorClassLibrary\RazorClassLibrary.csproj]

Tried with below options

1. Removed obj folder
2. Restore Nuget Package
3. Visual Studio update
4. MSBuild update
5. Added <RuntimeIdentifier>android-arm64</RuntimeIdentifier>

Spending more than two days, Really appreciate any guide to resolve this issue.

Answer 1

I suggest you try this

1. In Library project.csproj replace TargetFramework by plural -> <TargetFrameworks>net6.0;net6.0-android</TargetFrameworks>
2. In App project.csproj, I set android to API21, in my case with API31 didn't work.
3. In App project, right click, properties, Go to Android / Options / Package Sign, and complete complete info from keystore
