C# Extension version:
1.10.0-beta3 dc1908d

Steps to reproduce

1. Enter "if", it will show "if" snippet item in autocomplete list.
2. Enter space as part of "if (xxx)" expression, it will show methods list, "if" snippets will disappear.
3. Enter "(" as part of "if (xxx)" expression.

Expected behavior

Autocomplete with closing pair of parenthesis ")", or nothing. Even I try to insert "IF"-snippet with tab-key - it will do it only on second attempt (first one is just closing autocomplete popup). Totally not usable when you write condition expression in fast manner.

Actual behavior

Automatic insertion of first item at autocomplete list.

Unfortunately, I'm unable to reproduce this. I tried the following:

1. Create new C# file.

2. Type class and press TAB followed by ENTER to expand the 'class' snippet and position the caret inside.

3. Type svm and press TAB to create a new static Main method with the caret positioned inside.

4. Type if to display the completion list with the 'if' snippet selected.

   

5. Press SPACE. At this point your repro steps state that a completion list of methods appears, but it doesn't (and shouldn't).

Could you clarify your repro steps? Thanks!

@DustinCampbell very strange behaviour, btw. Looks like it depends on base class methods. I recorded video with issue (it raised only on first attempt).

@DustinCampbell in my case happens it:

I write if and press space then if snippet appears and when I press any key its happen:

[DustinCampbell]

@Leopotam: Thanks for the video. That is very strange behavior. 😄 I notice that you're using VS Code Insiders. I wonder if the issues is there. I'll install and take a look.

@bernardbr: The behavior you described is different than what @Leopotam is seeing. Note that in your example there is code after the "if".

@DustinCampbell

Yeah, I realized that now ... I'm sorry.
But, it's a strange behavior. It's happening with using statement too.
But thinking now, maybe it isn't a behavior of omnisharp. I'm gonna try to do the same with only omnisharp extension enabled.

@DustinCampbell class was created in unity3d solution - its why i can used UnityEngine.MonoBehaviour class. All methods at popup list are valid methods of MonoBehaviour type.

[DustinCampbell]

@Leopotam: I don't have Unity set up to precisely repro. Do you see the same problem on the RTM version of VS Code?

[bernardbr]

@DustinCampbell Sorry about my first comment. This behavior wasn't of Omnisharp. I disabled all other extensions and the problems gone.

Thanks for your attention!

[DustinCampbell]

@bernardbr: Glad to hear it -- thanks @bernardbr!

[Leopotam]

@DustinCampbell i uploaded minimal unity3d-solution, you can try to reproduce issue on it.

[DustinCampbell]

Thanks! I can totally repro with this solution.

[DustinCampbell]

OK. I can repro with a smaller code example:

class Base
{
    public void Invoke(float value) { }
}

class Derived : Base
{
    public void M()
    {
        // if here
    }
}

[DustinCampbell]

OK. I see what's wrong.
