For most cases you can use Rider, which has a native Linux version. It doesn't do database projects so if you use MSSQL without an OEM ORM you're gonna want at least VS Code, but other than that it works fine.

Of course if you're a .NET developer in a corporate environment you probably don't have a choice as you're already using a Windows VM through Azure Virtual Desktop just so that your company can chain itself harder to daddy Microsoft.
