MissingMethodException raises in my confused assembly with .Net 3.5

[magneticcore]

I target my assembly containing controls for Visual Studio to .Net 3.5 with license support (VB.net).

After confusing it with ConfuserEx 1.0.0 (anti-tamper and constants), when the license is validated in Visual Studio, my assembly raises a MissingMethodException on Boolean System.Reflection.MethodInfo.op_Inequality(MethodInfo, MethodInfo) that is only included since .Net 4.0.

Without confusing it or confusing it with .Net 4.0 or 4.5, my assembly works normally. Note: I built ConfuserEx with .Net 4.0

Where in the source code can I find this kind of problem?

Thank you.
