NET-1685 Analysis warnings in .razor files cannot be suppressed

[costin-zaharia-sonarsource]

Description

There are multiple ways to suppress analysis warnings:

• using .editorconfig files
• using #pragma warning disable directives
• using the SupressMessage attribute Details: https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/suppress-warnings

Currently none of these work for .razor files.

Repro steps

Create a project with a .razor file that contains the following snippet:

@code {
#pragma warning disable S5332
    public void Do()
    {
        using var smtp = new SmtpClient("host", 25);
    }
#pragma warning restore S5332
}

Expected behavior

The issue should be suppressed.

Actual behavior

The impression does not work.

Known workarounds

Mark the issue as won't fix/false positive or review the hotspot on the server

The same is true for Razor templates in .cshtml files as well.

I confirm: via .editor.config, it doesn't work too with this configuration:

Moved to NET-1685

@pavel-mikula-sonarsource is this indeed completed, or did you close it because of the move? Asking because the latest release (https://github.com/SonarSource/sonar-dotnet/releases/tag/10.11.0.117924), published after this being closed, doesn't seem to contain it.

It was only moved. I'll reopen it so you can get an update once it's done. We've kept opened mostly FPs

Thank you!
