title: Visual Studio during Debugging: The function evaluation requires all threads to run
body: <p>I'm suddenly getting a strange error while debugging. Up to now the variable in the watch windows has been showing correctly. Now I am always getting this error message in the watch windows:</p>
  <blockquote>
  <p>The function evaluation requires all threads to run</p>
  </blockquote>
  <p>I am not able to check any variable anymore. I am not explicitly working with threads. What can I do to get it working again?</p>
  <p>I already disabled, as mentioned in some forums, the function: &quot;Enable property Evaluation and other implicit function Calls&quot; in the option window of the debugger. But without success, and it gives me this error:</p>
  <blockquote>
  <p>Error Implicit Function evaluation disabled by the user</p>
