Android application type

.NET Android (net7.0-android, etc.)

Affected platform version

.NET 8 Preview 2

Description

A customer's app won't get past the splash screen when built in Release mode:

But it appears to work if you set AndroidEnableMarshalMethods=false.

Steps to Reproduce

  1. I can share the sample with you privately in Teams
  2. Run the app in Release mode. It can be a fresh/clean build, so not an incremental build issue.

Did you find any workaround?

AndroidEnableMarshalMethods=false

Relevant log output

The log just kind of gets here... And stops?

    I've also ran into this issue as well. The above workaround solves it.

    We are turning off AndroidEnableMarshalMethods for .NET 8. Bumping to .NET 9 when we will try to fix and finish the feature.
