Questions tagged [visual-studio-mac]

Visual Studio for Mac is an IDE from Microsoft for Mac users. Use this tag if you have a specific question about Visual Studio for Mac features and functionality, not just a question regarding your code. Please mention your exact macOS version, VS for Mac version, Mono version and Xamarin runtime versions when applicable. Information such as Xcode and Android SDK versions are also useful.

Microsoft released Visual Studio for Mac in 2017 (based on MonoDevelop 7.0 code base), to replace Xamarin Studio (it was based on MonoDevelop 6.0 code base).

Primarily it supports Xamarin (Xamarin.Mac, Xamarin.iOS and Xamarin.Android) and .NET Core projects. Other project types might not be supported very well (due to Mono/.NET Framework compatibility).

Not every features of Visual Studio 2017 on Windows are supported by Visual Studio for Mac.

Product defects can be reported to Microsoft via Help | Report a Problem. Feature requests can also be raised via Help | Provide a Suggestion.

Is there a way to make Visual Studio for Mac OS recognise the case of a filename?

In VS on Mac OS when I try to rename a file then if the file exists with a different case it won't let me rename it. Is there any way around this. Seems like something I would have thought would have been fixed 20 years ago :-(
