C# syntax error hints disappear after a few seconds

C# syntax error hint disappears after a few seconds.

Steps to Reproduce:

1. make a C# file
2. install C# plugin (1.4.1)
3. write a simple C# class
4. intentionally cause a syntax error.
5. observe red hints on the syntax error.
6. wait a couple of seconds, error hints disappear.

I expect this to be a VSCode issue instead of OmniSharp, since the syntax hints did show up correctly, only to disappear in a couple of seconds.

@zeyangl I'll say let's start with OmniSharp as we don't know yet whether OmniSharp regards it as no longer an error after a couple of seconds, please file issues there and if OmniSharp confirms there is not any C# or OmniSharp related stuff, let's then take a look into it.

It appears to be fixed in 1.7.1 release. OmniSharp version remains the same though, so probably a nice side effect of some other fix in vscode.

I am still having same issue on Ubuntu 14.04, insiders and stable Version 1.7.1.
Maybe is because of big projects, the problem doesn't occur when testing a small project.

Initially i was suspecting the auto save feature to have something to do about it, but i tested with all possible options.

Warnings and info remain, but errors disappear about 2 seconds after code change (saved or not).

Same project works fine in Windows with vscode 1.7.1
