.NET 6.0.6: DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 doesn't work any more

[ww898]

Windows x64 .NET SDK 6.0.301. Languages: en-us, de-de, ru-ru. DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 doesn't work any more.

sample.cmd:

set DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=true
dotnet new console

Console output:

> dotnet new console
The template "Console App" was created successfully.

I do not repro with that SDK:

> set DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=true

> del inv.csproj Program.cs

> dotnet new console
The template "Console App" was created successfully.

Are you seeing this consistently? Does this only happen if the primary OS language is non-US-English?

Stumbled upon this issue while investigating how to work around the MSBuild slowdown caused by dotnet/runtime#31273. (I guess DOTNET_SYSTEM_GLOBALIZATION_PREDEFINED_CULTURES_ONLY=0 (if combined with chcp 65001) should be relatively safer in this specific case, though.)

Does this only happen if the primary OS language is non-US-English?

Seemingly yes. Specifically, the difference is the codepage. Codepage 932 (Shift JIS, Japanese) reproduces the issue. 437 (OEM US) and 65001 (UTF-8) are fine.

Repro:

chcp 932
dotnet new console
set DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1
dotnet build
chcp 437
dotnet build

D:\home\tmp\ConsoleApp>chcp 932

I guess the exception is raised here (new CultureInfo("en-US")): https://github.com/dotnet/msbuild/blob/2badb37d109910fbd3155cf8743224b7a27494d8/src/MSBuild/XMake.cs#L1478-L1488

(In .NET 6) In the globalization invariant mode CurrentUICulture and CultureInfo.CurrentUICulture.GetConsoleFallbackUICulture() are the invariant culture. CurrentUICulture.TextInfo.OEMCodePage and CurrentUICulture.TextInfo.ANSICodePage are 437 and 1252 respectively. Therefore 65001, 437 and 1252 are fine while others fail.
