v 4.4.2 crashes with .NET 4.6

[criistii]

Hi,
I recently updated to Firebase 4.4.2 on a Unity project I am working on. The project uses .NET 4.6 under Unity 2017.3.1f1.

As soon as I call FirebaseApp.DefaultInstance, the editor crashes. I was able to reproduce the bug in a blank project. If the project is .NET 4.6 the editor crashes. If the project is .NET 3.5, everything is fine.

Please advice.

Thanks,

I'm surprised to hear that it crashes the editor, we know that currently compilation will fail. Do you have the editor log from the crash?

That said, we have a workaround documented here https://groups.google.com/d/embed/msg/firebase-talk/2w1Lk62VIcg/_laCr8JzAAAJ

• Check out https://github.com/stewartmiles/Parse-SDK-dotNET/
• Build the Unity.Compat.TypeForwards/Unity.Compat.TypeForwards.csproj project
• Drop Unity.Compat.dll into your project over Assets/Parse/Plugins/dotNet45/Unity.Compat.dll

The proposed option did not work. I compiled the project both debug and released, and tried both versions of the dll. The editor is still crashing.
I am attaching the log file in case it helps.
In the meantime, can you point me to where I can get an older version of Firebase, so I can continue working?

@a-maurice the stack trace is pointing at some code you was poking at recently, ring any bells?

@criistii thanks for reporting.

All prior releases are available from

https://dl.google.com/firebase/sdk/unity/firebase_unity_sdk_VERSION.zip

e.g

https://dl.google.com/firebase/sdk/unity/firebase_unity_sdk_4.4.0.zip

4.4.1 was broken due to the iOS SDK it depends upon being revoked.

Small update: I spent most of the day today trying to fix this. I tied different Unity versions and different Firebase versions (as low as 4.2.1). All of them are crashing in .NET 4.6 mode. Not sure how to fix this.

@criistii there must be something "different" with your machine vs. our test environments. What's the host operating system, Windows, OSX, Linux? Anything else you can share?

I am working under MacOS 10.13.3. I did several clean installs of unity (moved the app to Trash). In case there are any caches I am not aware of, please let me know.
If you need more information, I would gladly help. Just let me know what you need.

Thansk,

@criistii, @patrickhoh patched the Unity SDK in 4.0.3 to workaround a Unity bug that broke certificate installation on OSX, essentially breaking the real-time database in the editor. However, Unity have fixed their bug and now our workaround is bringing down the editor. We have a patch internally which we're running through QA so expect a release to be posted next week.

In the meantime, I've attached a patched Firebase.Platform.dll (it's zipped) which you can use to replace Assets/Firebase/Plugins/Firebase.Platform.dll in the latest release of the SDK to workaround this issue.

We just released a fix for this in Firebase Unity 4.4.3. https://firebase.google.com/support/release-notes/unity#4.4.3
