ASP.NET Razor formatter removes duplicate spaces in a string value

[RomanKoff]

Type: Bug

Issue Description

If you specify multiple spaces in a row in the value of a string variable and apply code formatting, the double spaces will be replaced with a single space. This is unacceptable.

Before: var s1 = " test test ";

After formating: var s1 = " test test ";

Thanks for the report @RomanKoff, unfortunately I can't repro the issue, and judging from the video it seems like for whatever reason that code is not being seen as C#. You can see in the video how, when you place the cursor to the left of test it highlights the word, but that doesn't happen inside string literals.

Would it be possible for you to share more details of your setup? What version of the extension are you using? Do you have the OmniSharp setting turned on? Could you share the whole Razor file that you're editing in the video?

If it's easier, running the "Razor: Report a Razor issue" command in VS Code should capture all of the relevant details for us.
