2. Build it to UWP or WSA
3. Notice Reference rewriter errors in console
Reference rewriter: Error: method `System.Void TestNamespace.TestBug`1/EInner<System.Int32>::Unity_Serialize(System.Int32)` doesn't exist in target framework. It is referenced from Assembly-CSharp.dll at System.Void TestNamespace.Test::Unity_Serialize(System.Int32).
UnityEngine.Debug:LogError(Object)
PostProcessWinRT:RunReferenceRewriter() (at C:/buildslave/unity/build/PlatformDependent/WinRT/SharedSources/CSharp/PostProcessWinRT.cs:573)
PostProcessWinRT:Process() (at C:/buildslave/unity/build/PlatformDependent/WinRT/SharedSources/CSharp/PostProcessWinRT.cs:126)
UnityEditor.PostprocessBuildPlayer:Postprocess(BuildTarget, String, String, String, Int32, Int32, String, String, BuildOptions, RuntimeClassRegistry, BuildReport)

Reference rewriter: Error: method `System.Void TestNamespace.TestBug`1/EInner<System.Int32>::Unity_Deserialize(System.Int32)` doesn't exist in target framework. It is referenced from Assembly-CSharp.dll at System.Void TestNamespace.Test::Unity_Deserialize(System.Int32).
