[WASM] Invariant culture doesn't work

[pranavkm]

Blazor added a test to verify that CultureInfo.InvariantCulture works in WASM. This is failing since upgrading to .NET 5.

// This test verifies that invariant cultue works correctly in WebAssembly environments. The test case is based on the discussions here: https://stackoverflow.com/a/20085219
var string1 = "Strasse";
var string2 = "Straße";

var ordinalComparison = string1.Equals(string2, StringComparison.Ordinal);
var invariantComparison = string1.Equals(string2, StringComparison.InvariantCulture);

Console.WriteLine(ordinalComparison + " " invariantComparison);

Expected: False True
Actual: False False

@pranavkm I would hold logging more issues till figuring out if the wasm enabling the invariant globalization mode or not. with this mode, you lose almost all globalization support.

I set the milestone to 5.0 since it is related to WASM.

Since ICU is going to be enabled for blazor, is this still an issue?

I think we can close this now... also now in .NET 5.0, InvariantMode is the same for WASM and non-WASM, before it was the Mono Globalization implementation which differed.
