Description

I have a unit test class with a test method somewhere around halfway in the file. Syntax coloring does not work for the second half of the file. After trying to figure out what the issue is, I have determined that the string listed in the steps to reproduce is causing the syntax coloring to quit working. It should be noted that the class file compiles and all the test methods in the file run without issue.

Hello,

Thank you for reporting this issue. The Editor stops syntax coloring after encountering long lines for performance reasons and by default the threshold is 32k. We will certainly improve the experience in future versions depending on the customer feedback.

As a workaround, you can change this threshold by creating a registry key:

HKCU\Software\Microsoft\VisualStudio\11.0\Text Editor\Global Options

and in that key creating a DWORD value with name "LongBufferLineThreshold" and set it to whatever value you like as the new limit.

Thanks,
Murali Krishna
Program Manager,

Move this function, or introduce constants, to the end of the class.
