InlineData attribute with certain characters (e.g. 'ä','ö',etc.) breaks VS Test Explorer

[albpi]

Description

The program uses the File.Exists method to check that the passed filename value is actually present at the specified path. While it works fine when running in the Console App, it fails when setting up a test with VS Test explorer, if the value contains characters like 'ä' or 'ö' (and I suppose it will fail for other special characters) .

I think this issue is identical to this one.

Steps to reproduce

I am using .NET 7 and here is the test project setup:

I want to check that a file with name testä.xml exists. I have it in a folder and the relative path to it is ..\..\testä.xml
The method that fails in VS Test explorer is File.Exists .".\..\testä.xml".
It also fails when using dotnet test, that I believe is what VS Test uses under the hood.

Expected behavior

The result of File.Exists "..\..\testä.xml" should be true and the test should then succeed.

Actual behavior

The result of File.Exists ".\..\testä.xml"is false and the test then fails.

Environment

Windows OS 11

I see this too. A fix would be helpful.

I encountered this bug also. This should be fixed asap.

Used the repro linked in xunit, and this looks fixed:
