When tracing, many property set() statements are not properly traced by the

In some cases, tracing successfully enters the set() function of the property,
but in some other cases, it does not enter it and appears to skip it. Putting
breakpoints inside the set() function of the property does not work, making
believe the code is not executed at all.

However, adding some System.Diagnostics.Debug.WriteLine() statements shows the
code gets executed, it just cannot be properly traced, and breakpoints are

Reproducible: Always

Steps to Reproduce:
My solution is quite small, with only a few classes coming from class library
assemblies. I am guessing reproducing the problem should not be too hard in a
complex project.
Actual Results:  
The tracer does not always get inside the set() functions of the properties
when hitting F11 on it. Sometimes it does, other times it just doesn't. It is
always the same properties that work, and the same properties that don't work,
from what I could observe.

Expected Results:  
The debug tracer should enter the set() function of all the properties.
