Ensure C# exceptions are English

[RedMser]

Our GUI checks some error messages to detect what happened (e.g. "is being used by another process" IO error).

A non-english system will use non-english error messages I believe, so these checks would fail. Needs testing since I'm not sure if this changed with newer .NET versions.

Ideally all errors are set to be english, also so that bug reporting is easier.

I tried following code and the exception was still in English:

Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("de-DE");
CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("de-DE");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("de-DE");

int[] numbers = new int[] { 1, 2, 3 };
int result = numbers[-1];

Might be different in .NET 8.0 but it's really hard to find info about this topic online. If anyone with a non-English system can experiment, it would help me a lot. Maybe it's all-English by default and nothing needs to be done??
