This isn’t my research, but uses a technique that seems to have been discovered(? idk) by the Social Engineering Toolkit (SET) guys. The goal of this technique is to allow the unsafe keyword to be used when building C# inline msbuild tasks via XML.

Reading innumerable stack overflow answers assured me, the problem was simple! For I must be the fool; how could so many accepted answers to what seemed to be my exact issue be mistaken?
