(C#) Assigning a variable in code sample brings to tottaly different highlight

[HedgehogNSK]

Describe the issue Hello. I'm using your extension for blogger platform. I just found out that if sample of code doesn't contain any variable assignment, then highlighter doesn't determine that the language of a sample is C#. I use "vs2015" style template

Are you using highlight or highlightAuto? I use snippet from the highlight homepage. If this question asks do I set language name in <code> tag explicitly? Then the answer is: I tried them both to determine the issue.

Sample Code to Reproduce

public partial class MainWindow : Window
{
    DisposableBag disposable; // DisposableBag is struct, no need new and don't copy

    public MainWindow()
    {
        Observable.IntervalFrame(1).Subscribe().AddTo(ref disposable);
        Observable.IntervalFrame(1).Subscribe().AddTo(ref disposable);
        Observable.IntervalFrame(1).Subscribe().AddTo(ref disposable);
    }

    void OnClick()
    {
        Observable.IntervalFrame(1).Subscribe().AddTo(ref disposable);
    }

    protected override void OnClosed(EventArgs e)
    {
        disposable.Dispose();
    }
}

When I don't set language explicitly <code>:

When I set language explicitly <code class="cs">:

When I don't set language explicitly, but I add assignment of some value (ex. var x = 1;):

Expected behavior

1. AutoDetection has to detect C# language even if there is no assignment of any variables.
2. Names of classes, methods, types, as well as keywords as "ref", "class" etc have to by highlighted

The code you provided auto-detects to scss.

scss: relevance 21, csharp: 19

I don't know how to "fix" it, or even if it needs to be fixed. Auto-detect is difficult and should probably not be used, as it will be deprecated with v12.0 anyway, I believe. It's best to specify the language for each of your snippets.

Yeah, we make no guarantees about auto-detect, it's more of a toy than a precision tool. Specify the language and you'll get much better results.
