.NET 8 RC1 silently breaks binding library (build successful but no binding generated)

[bruno-garcia]

Android application type

.NET Android (net6.0-android)

Affected platform version

8.0.100-rc.1.23455.8

Description

While trying to get the Sentry .NET SDK to build with the .NET 8 SDK, I encountered a problem with the net6.0-android binding library that blocks things.

Steps to Reproduce

Repro: https://github.com/bruno-garcia/repro-dotnet-sdk-8-rc1-bindings-android/tree/main

Build with .NET 7:

• Build successful
• DLL contains C# methods that bind to Java methods

Build with .NET 8:

• Build successful
• DLL is empty

Did you find any workaround?

No

Relevant log output

No response

It is expected that .NET 8 SDK cannot compile the out-of-support net6.0-android framework:
#7900

Attempting to do so produces the following error:

error NETSDK1202: The workload 'net6.0-android' is out of support and will not receive security updates in the futur
e. Please refer to https://aka.ms/maui-support-policy for more information about the support policy.

This sample project is suppressing the error with:

<NoWarn>NETSDK1202</NoWarn>

Thus no error is produced, but also the project isn't going to work.
