Mobile Platforms

Triage and fix .NET failures on Apple mobile (iOS, tvOS, MacCatalyst) and Android in dotnet/runtime.

Why mobile is different

Mobile platforms run .NET on devices and simulators/emulators where the host OS controls code execution. Apple forbids JIT in production (simulators allow it), requires code signing, and has six OS variants that often need identical handling. Android requires cross-compilation and APK packaging across four architectures. Both surface failures invisible on desktop: provisioning errors, emulator boot timeouts, app bundle signing, native toolchain mismatches.

CoreCLR is the primary runtime. NativeAOT is the default publish framework for ahead-of-time compilation. Mono also runs in CI alongside CoreCLR.

CI pipeline

Mobile tests run in the runtime-extra-platforms pipeline (AzDO definition 154, org dnceng-public, project public), daily on main and on relevant PRs.
