Visual Studio during Debugging: The function evaluation requires all threads to run

Question

I\'m getting suddenly a strange error while debugging. Up to now the variable in the watch windows has been shown correctly. Now I am getting always the error message in the

Answer 1

I ran into this issue when just trying to get items from a table called "AGENCY" using Entity Framework:

var agencies = db.AGENCY.OrderBy(e => e.FULLNAME);

Hovering over agencies in debug mode, clicking to expand the options, and clicking Results would give the dreaded "The function evaluation requires all threads to run" with a "Do Not Enter" icon at the end that, on which, clicking did nothing.

2 possible solutions:

1. Add .ToList() at the end:

   var agencies = db.AGENCY_TABLE.OrderBy(e => e.FULLNAME).ToList();

   List agencies = db.AGENCY_TABLE.OrderBy(e => e.FULLNAME).ToList();

   Credit goes to Hp93 for helping me come to this solution. In the comments on MUG4N's answer where I found this solution, it also mentions trying .Any() instead of .ToList(), but this gives a Boolean instead of a , like is, so it probably wouldn't help.

2. Workaround - try a different path in the debug options. I found that I could click on the "Non-Public Members" > "_internalQuery" > ObjectQuery > Results View and get my values that way.
