Engine Build errors

Explanation

Bridge.NET is an open source C#-to-JavaScript Compiler, that helps us with converting Unity projects into lightweight HTML5 playables. Along with gaining the many benefits of using Bridge.NET, we also intern inherit some of its limitations. (Such as only supporting C# features from 7.0 and previous).

It is likely that one of these limitations is causing the error you are seeing.
