MethodBoundaryAspect.Fody: Common Language Runtime detected an invalid program

Hi team, last week I have a bug on production site This is a case that caused bug (I call it as “FAKE” code - short code to reproduce):

[TimeTakenTrackLog]
public class Demo
{
    public static async Task DoNothing()
    {

    }

    public static async Task DemoBugAsync(int value)
    {
        if (value > 0)
        {
            await DoNothing();
        }
    }
}

// My page
[TimeTakenTrackLog] // applied on class
protected void Page_Load(object sender, EventArgs e)
{
    Demo.DemoBugAsync(5).GetAwaiter().GetResult();
}

// My aspect attribute
public class TimeTakenTrackLogAttribute : OnMethodBoundaryAspect
{
    public const string MessageQueueKey = "ImMethodTimeTakenMsgQueue";

    public override void OnEntry(MethodExecutionArgs args)
    {
            
    }

    public override void OnException(MethodExecutionArgs args)
    {
           
    }

    public override void OnExit(MethodExecutionArgs args)
    {
        if (args.ReturnValue is Task t)
        {
            t.ContinueWith(task => {
                BuildTimeTakenData(EventType.OnExitAsync, args);
                EnqueueTrackMessage();
        });
        }
        else
        {
            BuildTimeTakenData(EventType.OnExit, args);
            EnqueueTrackMessage();
        }         
    }  
}

=> It’s just a piece of “real” code I applied to production last week (but it can cause error) => Fake code cause error on both DEBUG and RELEASE, local site & production site => “Real” code worked on Local (Debug mode)/TEST (Release mode) site BUT DID NOT work on Production site (RELEASE mode)

---

Here is a mini version of real code:

Caller:

WriteDbAccess.InitOrderRequestAndParseSubTrackData(new OrderRequestItem
{
    OrderId = trackRequestData.OrderId,
    SupplierId = supplierId,
    OrderStatus = OrderStatus.New
}, NewPORequest, response).GetAwaiter().GetResult();

=> And here is method InitOrderRequestAndParseSubTrackData in class WriteDbAccess: I used Dapper btw

public static async Task InitOrderRequestAndParseSubTrackData(OrderRequestItem dto, NewPORequest xmlRequest, NewPOResponse xmlResponse)
{
    using (var conn = new SqlConnection(Settings.ConnectionString))
    {
        conn.Open();

        var poIdNumber = xmlRequest?.PurchaseOrder?.purchaseOrderId;
        if (poIdNumber != null && poIdNumber > 0)
        {
            var exists = conn.ExecuteScalar<bool>("select top 1 1 from dbo.YOUR_TABLE where PurchaseOrderId = @poId", new { poId = poIdNumber.ToString() });

            if (!exists)
            {
                var parms = new DynamicParameters();

                parms.Add("@orderId", dto.OrderId);
                parms.Add("@supplierId", dto.SupplierId);
                parms.Add("@orderStatus", dto.OrderStatus);

                await conn.ExecuteAsync("InsertOrderRequest", parms,
                            commandType: CommandType.StoredProcedure, commandTimeout: Settings.ConnectionTimeout);

                await ParseOrderRequestSubTrackDataAsync(dto.OrderId, xmlRequest, xmlResponse);
            }
        }
    }
}

Remember that Real code work on local and test site, but it did not work on Production site 😦

!!! FYI: My Aspect attribute work good, I have some web services and aspect worked for those services, only one of them did not work

This can be a bug of Fody , not MethodBoundaryAspect.Fody but I don’t know So anyone can explain why please
