Bug: Microsoft.Diagnostics.Tracing.EventSource fails to generate manifest when using a byte enum.

Question

Not sure where to post issues with this library, so I'm trying here.
This problem occurs with both
Microsoft Event Source Library 1.0.26 and the latest pre-release
Microsoft EventSource Library 1.1.13-beta
When building the following program an error occurs during manifest generation.
public enum MyEnum : byte
One,
Two,
Three
[EventSource(Name = "My-EventSource")]
public sealed class MyEventSource : EventSource
[Event(1, Channel = EventChannel.Admin, Message = "My value: {0}")]
public void MyEvent(MyEnum myEnum)
WriteEvent(1, myEnum);
error : MSXML Schema Validation Error 0xc00ce16a. At Line=13, Column=56, Union doesn't support this value.
If I change the enum type to have "Int32" as its underlying type however, everything works as expected.

Hello Peter,
>>error : MSXML Schema Validation Error 0xc00ce16a. At Line=13, Column=56, Union doesn't support this value.
For this issues, it seems to be caused by the eventRegister.exe which is installed with the Microsoft.Diagnostics.Tracing.EventSource 1.0.26, because if I use the System.Diagnostics.Tracing namespace instead, it works fine even with the byte. I think
the team might have changed its insider implementation(I am not sure since the package on nuget is not open).
My suggestion for this issue is that you could post this feedback to the site below:
