[BUG] Memory increasing with ActivityOutputRecord

[iio888]

Description

Program memory will increase continuously when execute a activity with result in a loop.

Steps to Reproduce

Here is my workflow to run.

internal class EndlessWorkflow : WorkflowBase
{
    protected override void Build(IWorkflowBuilder builder)
    {
        builder.Root = While.True(new If(c => true) 
        {
            Then = new Inline(c => Console.WriteLine(“loop”)
        };
    }
} 

Actual Behavior

The number of _records in ActivityOutputRegister is increasing continuously. The memory is going to be 700M after 15 min.

Environment

• Elsa Package Version: 3.2.3

I noticed that there is a similar issue #4900 which has been closed. But I think the core problem has not been resolved. The real reason causes this issues is that the activity (If in my example) is setting result continuously (calling context.Set method) and the ActivityOutputRecord is created continuously at the same time.
In my example code, my workflow won’t exit. So ActivityOutputRegister won’t be disposed, too.
