Crash on Android (regression in 1.2.6)

[tranb3r]

On Android, my app crashes when using new version 1.2.6.
No issue with previous versions.

Here is the stacktrace:

System.TypeInitializationException : The type initializer for 'System.Linq.Dynamic.Core.Parser.EnumerationsFromMscorlib' threw an exception.

Any idea ?

Hello @tranb3r, this issue is indeed related to 1.2.6 (can you maybe create a very small android example project which has this error?)

As a workaround you can use ParsingConfig and set SupportEnumerationsFromSystemNamespace to false.

Here is a repro

I confirm the workaround does work.

Hello @tranb3r.

I cannot test android on my system, can you try NuGet 1.2.7-preview-01 from https://www.myget.org/F/system-linq-dynamic-core/api/v3/index.json ?

Hi @StefH,
I confirm the 1.2.7-preview-01 does work on android.
Thanks for the quick fix !

@tranb3r Thanks for verifying. I'll close this issue now and when the next official NuGet is released, this fix will included.
