Force SDK locale to English

[thomaslevesque]

Apparently the SDK for .NET 5 has been localized. I'm sure it's great for some people, but I don't want this. I want the SDK to "speak" English, not French.

My Windows language is English, with French regional settings (for date and number format, etc.)
(in other words, CurrentUICulture is English, CurrentCulture is French)

How do I force the SDK to use English?

Any news on this?

For now, renaming the "fr" folder in %PROGRAMFILES%/dotnet/sdk/{version} seems to do the trick, but it feels like a hack...

You should be able to set the DOTNET_CLI_UI_LANGUAGE environment variable to a different language.

Do note that the SDK has been localized for a long time (1.0?), that override was added around the 2.0 timeframe i believe.
So it would be more interesting why it never was localized on your system to begin with..

Thanks @dasMulli!

I was wondering the same thing. I noticed the localization folders in previous versions of the SDK, but I never had to do anything to override the language before. Maybe the heuristics for selecting the default language have changed in 5.0?

I'll close this issue, since there's a documented solution

OK, I think I know what the problem is. It's not a problem with the CLI, but with .NET itself.

Consider the following code:

static void Main(string[] args)
{
    Console.WriteLine($"Culture:\t{CultureInfo.CurrentCulture}");
    Console.WriteLine($"UI Culture:\t{CultureInfo.CurrentUICulture}");
}

If I build and run it in .NET Core 3.1, the output is this:

Culture:        fr-FR
UI Culture:     en-US

(which is what I expect based on my system settings)

If I build and run it in .NET 5.0, the output is this:

Culture:        fr-FR
UI Culture:     fr-FR

It looks like .NET 5.0 only considers my regional settings, not my UI language.
