Exception with stack trace pasted below thrown when building with "Link framework SDKs only" when using CouchBase.Lite and getting an instance of the Database. Downgrading to XI 220.127.116.11 resolves the issue.
# Steps to reproduce
1. Open the attached test project in Xamarin Studio (Mac)
2. Ensure that linker option is set to "Link framework SDKs only"
3. Deploy app to device or simulator.
Expected behavior: No exception thrown.
Actual behavior: System.TypeInitializationException is thrown (it is caught and written to the console) with the following stack trace
>System.TypeInitializationException: The type initializer for 'Couchbase.Lite.Util.Log' threw an exception. ---> System.NotSupportedException: Linked Away

*** Bug 36177 has been marked as a duplicate of this bug. ***
The linker did not change but the BCL (mono) did - and include the code that triggers this.
* Add `-nolinkaway` to the "Additional mtouch arguments" of the project's option
* Larger application size (after linking)
Is the fix for the issue available on the latest Xamarin Stable Channel? I'm using Xamarin.iOS 188.8.131.52 and Xamarin Studio 184.108.40.206 (Build 3) and I'm still seeing this isssue.
@Tuan, no the fix requires several changes across repos and will require more testing before reaching stable. The workaround should (from comment #5) should work for you with only a small impact on the final code size.
Any ETA or estimate timeframe on when the fix will be available in stable? Using "Don't Link" actually increased on app size quite bit (20+ MB) and will definitely exceed the 100 MB cellular download limit.
@tuan, are you using "Don't Link" or just adding `-nolinkaway` under the "Additional mtouch argument"?
Those 2 options are different. As I understand it, `-nolinkaway` only changes a small subset of `mscorlib.dll`. "Don't Link" turns off linking for _all_ assemblies.
I'm using "Don't Link" as the linking behavior. I will try using the mtouch argument solution.
@Brendan Zagaeski thanks for pointing out the difference. Using the mtouch argument "-nolinkaway" only added a couple MB to the app size.
