> Failed to resolve "System.Void System.Runtime.CompilerServices.ExtensionAttribute::.ctor()" reference from "mscorlib, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b77a5c561934e089"
> mmp exited with code 1
## Steps to reproduce
1. Unzip attached test case.
2. Open the MutableAttributedTest project.
3. Attempt to run the project in Release mode so that `mmp` tries to link it with "Link All".
The ExtensionAttribute can't be resolved. It looks like the problem is that in TargetFrameworkVersion v4.0 this attribute is located in System.Core.dll rather than mscorlib.dll (see also bug #7888).
1. Workaround at the `mmp` step: set the target framework to 4.5  in the MutableAttributeTest.csproj project file.
>  <TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
2. Workaround at the `bmac` step: recompile the `NSAttributedStringExtensions` assembly using bmac, but add `--compiler=dmcs` to the command line . Copy the resulting `.dll` into the `MutableAttributedTest/lib` directory.
>  /Library/Frameworks/Xamarin.Mac.framework/Versions/Current/usr/bin/bmac -oNSAttributedStringExtensions.dll --sdk=4 --compiler=dmcs --tmpdir=/tmp -baselib=/Library/Frameworks/Xamarin.Mac.framework/Versions/Current/usr/lib/mono/XamMac.dll --ns=MonoMac.AppKit -r:System.Drawing NSAttributedStringExtensions.cs
Sorry for the delay in responding to this bug.
This appears fixed in the latest Xamarin.Mac. Please reopen if you still have problems with a more recent version.
