I installed and built UE4 from source - everything worked perfectly. I copied the mono over and did the checkouts for creating a new branch - everything worked fine. However when I try to compile it gives me the following error:
Error 1 error CS0234: The type or namespace name ‘Linq’ does not exist in the namespace ‘System’ (are you missing an assembly reference?) f:\UE4Source\UnrealEngine\Engine\Plugins\XamarinUE4\MonoRuntime\Source\ThirdParty\mono\EmbeddedMono.Build.cs 7 14 UE4
Mention: I tried manually adding a reference to System.Linq but can’t seem to find it.
Anyone knows if I can solve this? Or should I change the import in the code to something else?
