IStringLocalizer error: Input string was not in a correct format

Is there an existing issue for this?

I have searched the existing issues

Describe the bug

Input string was not in a correct format. Failure to parse near offset 1. Expected an ASCII digit.

Expected Behavior

format string

Steps To Reproduce

create resx file
create key and value{dateTime}: System is running.
localizer.GetString("{dateTime}: System is running.", DateTimeOffset.Now)

If change dateTime to 0 with resx file and code, that is running well.

localizer.GetString("{0}: System is running.", DateTimeOffset.Now)

Exceptions (if any)

No response

.NET Version

8.0

Anything else?

No response

I think the issue here is you're using a named parameter, not an index.

Your string should be {0}: System is running.

Yes, named parameter cannot be used? must be an index?

I believe so, as ultimately string.Format() is used:

aspnetcore/src/Localization/Localization/src/ResourceManagerStringLocalizer.cs

Line 119 in 3307bf6

    
           var value = string.Format(CultureInfo.CurrentCulture, format ?? name, arguments);

It's a pity! Is it possible to consider supporting named parameters like logger.Debug("{dateTime}: System is running.",DateTimeOffset.Now)?
