Why does the application show a compilation error? Doesn't it support /language feature here/?
The app uses the Roslyn compiler - full C# 8 compilation support.
Any compilation related error encountered is a syntax or logic error in your own code and thefore only adressable by you.
Does the app support GUI?
Yes, Xamarin.Forms.
Does the app support Windows.Forms?
No. Android OS != Windows.
It is impossible for Android to support Windows.Forms due to extreme incompatibility issues (no touch, no applicable mapping for most controls, incompatable layouts and heavy dependency on Windows API)
Why can't I close file/project?
Redundant operation. They are closed automatically when you open or create a new one.
Why was the application closed when when returning to foreground after a while?
It is a RAM intensive app. Other RAM intensive apps you use (like a web browser) will cause the system to kill resource consuming background processes like C# Shell when your RAM gets low.
Does the app support NuGet packages?
Yes, but not fully. Anything containing library dependencies that aren't .NET/C# won't work. Including Android bindings, at least for now.
Does the app support databases?
In general, yes. However a full ORM like Entity isn't properly supported.
Note that you would need to use Xamarin.MySql.Data instead of MySql.Data.
Does the app support scripts?
No, that might be confusing for people who aren't yet familiar with the C# language.
Does the app support creating class or page/xaml files?
Yes, from the "+" in the left project menu. It doesn't support automatically making classes in an already existing file, since that is the same as typing it somewhere.
Can I reference a ".dll" file?
Yes, from the "+" in the left project menu.
Does the app support external keyboards?
Yes. Including a few custom shortcuts (see settings).
How to fix "You need to declare the permission..." ?
You need to declare it from the "APK project settings" and then export as APK.
Is the app free?
Yes and no. There is a 14 day period where it is completely free in any situation.
After that there are 2 options for all functionality:
- A single time purchase for about 2 USD.
- An ad-supported model that actively requires an internet connection.
