Fixed NullReferenceException when project context not found #200

Closed jtbm37 closed 9 years ago

jtbm37 commented 9 years ago

I managed to raise this error while running :OmniSharpFindImplementations.

It seems that in my solution with several projects (40+) the server is unable to resolve the context of one of the project.

00053704 System.NullReferenceException: Object reference not set to an instance of an object.

Solution

A simple null check fixes it.
