It seems that disabling the linker allows things to work -p:PublishTrimmed=false.

Let me know if there is a particular managed type/method to look for, I can check if it was linked away. Thanks!

Reproduction Steps

1. dotnet new android
2. dotnet build -c Release -t:Run and run on an arm64 device

Expected behavior

Release net7.0-android apps launch successfully.

Actual behavior

Release net7.0-android apps crash unless you pass -p:PublishTrimmed=false.

Regression?

Yes this worked in: .NET SDK 7.0.100-preview.4.22174.1
Failing in: .NET SDK 7.0.100-preview.5.22256.2

Known Workarounds

-p:PublishTrimmed=false

Configuration

.NET SDK 7.0.100-preview.5.22256.2.

Looks to be using: 874c6a9

I was running on a Pixel 5 Android device.

@akoeplinger I suspect this might be linker related. Our functional tests that trim pass on CI. Could it be that we are on an older version of the linker?

[jonathanpeppers]

Ok, I found I could specify -p:InvariantGlobalization=true instead of setting -p:PublishTrimmed=false -- this also seems workaround this issue.
