Consider upgrading projects to either the Standard Term Support (STS) or Long Term Support (LTS) versions.

If any of these projects listed in this issue are intentionally targeting an unsupported version,
you can optionally configure to ignore these results in future automation executions.
Create a (or update the) *dotnet-versionsweeper.json* file at the root of the repository and
add an `ignore` entry following the
[globbing patterns detailed here](https://learn.microsoft.com/dotnet/core/extensions/file-globbing).

```json
{
"ignore": [
"**/path/to/example.csproj"
]
}
```

Apri snippets/visualbasic/System.Globalization/NumberFormatInfo/CurrencyNegativePattern/Project.vbproj e snippets/visualbasic/System/ICustomFormatter/Overview/Project.vbproj alle righe TargetFramework indicate. Aggiorna la destinazione non supportata alla versione supportata più vicina, quindi compila o convalida entrambi gli snippet per confermare che funzionino ancora.
