@grendello looks like there's new crash during startup with net6/preview2. I am not sure whether it is related to #5665, would you like to take a look? In the logcat from DotNetDebug test (https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=4512157&view=ms.vss-test-web.build-test-results-tab&runId=19348020&resultId=100007&paneView=attachments), I see this: |

Looks like The apkdiff output for before/after the bump I see that it is indeed missing (*1 means it exists only in the "before" apk): |
It's not new, it's handled and we merely print the exception, see here. I'm changing the code in my native net6 PR, you can safely ignore it here. |
Yes, my net6 PR stops using it, indeed |
Cool. Do you know when will this PR land in master? Or could you please add, if possible, a simplified fix to this PR? |

OK, we have new crash: |

^^^ @grendello Any idea? @steveisok Could that be a crash related to ICU? Does |

Looks like untrimmed apps run OK. I am going to try find out, what we are missing in trimmed assemblies. |

I think something changed in my code that parses .binlog files:
System.IO.InvalidDataException : No project build duration found in /Users/runner/work/1/s/bin/TestRelease/temp/BuildXAMLChangeTrueTrue/MyApp/msbuild.binlog
I remember seeing something where they made a new type for MSBuild messages -- maybe it caused this?
I might be able to take a look tonight, if not tomorrow morning.

I ignored the tests for now and filed:
@radekdoulik if this is green tomorrow, I would say go ahead and merge this. 👍

Fix `azure-pipelines.yaml` so that if (when) the `Mono.Android.NET_Tests` unit tests fail, the corresponding `.apk` or `.aab` file is uploaded for our later investigation; see also commit af7f7f5, which contained a "typo" such that .NET 6 packages *weren't* uploaded on unit test failure, as they used the wrong target framework identifier in the path. Finally, and most annoying of all, the `$(InvariantGlobalization)` MSBuild property should *not* default to `false` in .NET 6 projects, as was introduced in commit 9ac280c, but instead should default to *the empty string*. The problem is due to [`Microsoft.NET.Sdk.targets`][3]: <RuntimeHostConfigurationOption Condition=" '$(InvariantGlobalization)' != '' " Include="System.Globalization.Invariant" Value="$(InvariantGlobalization)" Trim="true" /> The above fragment sets `%(RuntimeHostConfigurationOption.Trim)` to `True` for `System.Globalization.Invariant` whenever `$(InvariantGlobalization)` is *not* the empty string. The value `false` is *not* the empty string. This caused `System.Globalization.Invariant`-related trim features to be enabled, which had the unfortunate and unanticipated side effect of causing ICU to *not* be properly initialized when running the `Mono.Android.NET_Tests` unit test apps, which resulted in a SIGSEGV: libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 31880 (droid.NET_Tests), pid 31880 (droid.NET_Tests) crash_dump64: obtaining output fd from tombstoned, type: kDebuggerdTombstone tombstoned: received crash request for pid 31880 crash_dump64: performing dump of process 31880 (target tid = 31880) DEBUG : *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** DEBUG : Build fingerprint: 'google/redfin/redfin:11/RQ1A.201205.011/6966805:user/release-keys' DEBUG : Revision: 'MP1.0' DEBUG : ABI: 'arm64' DEBUG : Timestamp: 2021-05-26 15:21:42-0400 DEBUG : pid: 31880, tid: 31880, name: droid.NET_Tests >>> Mono.Android.NET_Tests <<< DEBUG : uid: 10282 DEBUG : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 DEBUG : Cause: null pointer dereference DEBUG : x0 b400007c4de52530 x1 0000007fcc4cbeec x2 fffffffffffffff0 x3 b400007d2de37c80 DEBUG : x4 b400007d2de37cf0 x5 0000000000000004 x6 0000007c2225ddac x7 0000007fcc4cbfe0 DEBUG : x8 0000000000000000 x9 000000001333c921 x10 0000000000000000 x11 000000002de37cf0 DEBUG : x12 000000002a742e66 x13 0000000000000012 x14 0000000000000200 x15 0000000000000011 DEBUG : x16 0000007bd6adb810 x17 0000007ed2056240 x18 0000007ed3b94000 x19 0000007fcc4cc040 DEBUG : x20 b400007c4de52530 x21 b400007c4de52530 x22 0000000000000000 x23 b400007d7de490c0 DEBUG : x24 0000000000000001 x25 0000007bd58055c0 x26 0000007bd5cc0130 x27 0000007ed33ab000 DEBUG : x28 0000007bd6af1000 x29 0000007fcc4cbf00 DEBUG : lr 0000007bd69119c8 sp 0000007fcc4cbee0 pc 0000000000000000 pst 0000000080001000 … DEBUG : backtrace: DEBUG : #00 pc 0000000000000000 <unknown> DEBUG : #1 pc 000000000014e9c4 /data/app/~~oruJhhqj_EC_NWSaIGF_RQ==/Mono.Android.NET_Tests-G1iNxUwmGyu-tDRqYcK94g==/lib/arm64/libmonosgen-2.0.so (GlobalizationNative_GetSortHandle+76) (BuildId: 869ce5526fa884035199acac4ddc81bb6eeaf134) DEBUG : #2 pc 000000000000ddbc <anonymous:7c22250000> While we've (inadvertently) had `%(Trim)` enabled for over three months now, the *trigger* for this particular crash appears to be commit dotnet/runtime@bc27d49, which moved ICU initialization outside of the `GlobalizationMode` static constructor and into a new `GlobalizationMode.Settings` static constructor…which wasn't executed. Explicitly setting `$(InvariantGlobalization)` to the empty string *unless* it is the value `true` allows us to avoid setting `%(RuntimeHostConfigurationOption.Trim)`=True for `System.Globalization.Invariant`, which in turn avoids whatever set of linker-induced changes were preventing ICU from being properly initialized, which avoids the SIGSEGV.
