[manish]

Steps to Reproduce

1. Install Xamarin.Mac 4.5.0.221 or build from 256a3f5
2. Open XMBinding Sample https://github.com/xamarin/mac-samples/blob/master/XMBindingExample/XMBindingExample/XMBindingExample.sln
3. Set Target to "Full" and set linker to Don't Link
4. Build the solution

Expected Behavior

The build passes successfully

Actual Behavior

The build fails with

error MM4162: The type 'BusinessChat.BCChatButtonStyle' (used as a parameter 
in BusinessChat.BCChatButton..ctor) is not available in macOS 10.13.2 (it was 
introduced in macOS 10.13.4). Please build with a newer macOS SDK 
(usually done by using the most recent version of Xcode).

It passes with Linker set to Link Framework and the error message does not suggest this action

You need to enable --linkplatform, disable static registrar, not use XM master, or upgrade to xcode 9.3

The error is documented in XI and not XM (filing separate).

### <a name="MT4162"/>MT4162: The type '\*' (used as * {2}) is not available in * * (it was introduced in * *)\* Please build with a newer * SDK (usually done by using the most recent version of Xcode.

The registrar found a type which is not included in the current SDK.

Please upgrade Xcode.
