Question

Stepping over method without symbols - How to step into?

Answer 1

A:

If the namespace in question is a third party dll that didn't come with the symbols (pdb file) then this will occur. In order to "step into" the symbol file is needed.

If it's your own code then you would just need to double check that your symbol files exist. Having it set to debug at the project level should do this.

Yes, it's my own code, and i have set it to "Active (Debug)" at the Project level (and also the Solution level, as described in my initial question).I can see the .pdb files, in fact i deleted them manually and recompiled again so they get produced afresh.I expect both the frm.Show() and frm.Focus() method to step into frm_Activated event, as i press F8, but this does NOT happen. I have to put a break-point manually in this event.

Answer 2

+1 A:

I know this is an old question, but are you perhaps using yield functionality in a method that returns an IEnumerable?

For example (contrived):

public IEnumerable<object> GetObjects(IEnumerable<object> objects)
{
    foreach(var obj in objects)
        yield return obj;
}

I run into this in my unit tests often, but due to lazy evaluation, yield statements don't process until it is necessary. One way to force enumeration is to tack a .ToList() to the calling statement for example, though you wouldn't want to do that permanently unless the call is perhaps a test for some functionality where the enumeration itself isn't important.

So doing the following should result in enumeration:

GetObjects(new List<object>()).ToList();

In short, if you're calling a method that requires enumeration, but then never enumerate the result, you will get that error in the output. This could happen with LINQ statements as well, like .Select.

Edit: Didn't notice that it was a VB.NET project, but I'm pretty sure the principle still stands.
