描述

Version Used: 1.0.1

(Linux Ubuntu 16.04, Core i7 Skylake, 16GB)

I know this is not a "normal" kind of scenario by any means, but for good reasons I have a class with over eleven thousand methods and it takes quite some time to build, and totally kills VS Code.

I'm sure you have bigger fish to fry than caring about these kinds of fringe perf issues, but just letting you know in case you wanted to add a test like this to your test suite.

Best wishes

研究方向
Investigate the performance bottleneck in Roslyn's compiler when handling classes with a large number of methods. Examine the syntax tree and binding stages, using profiling tools to identify slow paths. Consider adding a test case for large classes as suggested in the issue.
