QUESTION
I'd like to use Prism in a WinUI 3 app, and I saw the Prism v8.1 release.
Additionally Prism 8.1 offers a new Prism.Uno.WInUI platform target for those wishing to build either native WinUI3, or Cross Platform WinUI 3 apps with Uno Platform.
I'm confused about Uno. I'm not using Uno, can I still use Prism in a WinUI 3 app without using Uno?
If yes, which packages do I need to install and in which projects? (I'd like to use DryIoc)
I guess Prism.DryIoc.Uno.WinUI must be added to the WinUI 3 app project.
But what about the other packages for using Prism?
...ANSWER
Answered 2022-Jan-10 at 12:59If you specifically want to use 'Dryloc', you could try to use one of these Nuget packages:
- Prism.Container.Extensions
- Prism.DryIoc.Extensions
They should both be of general use and not target a specific UI technology.
If you install 'Prism.DryIoc.Extensions' using the Nuget-Package manager, dependent packages should be installed automatically.
See Github - Prism.Container.Extensions
Note there is also a package 'Prism.Core' that does not target a specific UI framework either. If contains features like an event aggregator.
QUESTION
I have recieved a exercice to learn about data types in haskell and I can't figure out how to solve this one.
They got me a data like : data CatLista a = Nil | Unit a| Conc (CatLista a) (CatLista a) deriving Eq
and I need to make the data types become: Nil -> [] , Unit x -> [x] , Conc -> same operator as (++)
So if you run Conc (Unit 9)(Conc (Unit 5) (Unit 3)) == Conc (Conc (Unit 9) (Unit 5))(Conc (Unit 3) Nil)
should give true and Conc (Unit 9)(Unit 3) == Conc (Unit 3) (Unit 9)
should give false.
I already tried instancing the show class like this:
...ANSWER
Answered 2021-Dec-08 at 20:49Two values are not equivalent if these produce the same String
when calling show
on these. The (==) :: Eq a => a -> a -> Bool
function is implemented by the Eq
typeclass. You thus need to implement the instance
of Eq
for your CatLista
yourself.
The default implementation for Eq
, if you use deriving Eq
is that two values are the same if they have the same data constructor, and the parameters are elementwise equivalent by calling (==)
on these.
You thus can implement the instance for Eq
yourself with:
QUESTION
ANSWER
Answered 2021-Nov-21 at 11:57The problem is you are using spaces in the project name. Uno does not currently support this.
I also strongly discourage the use of spaces in the name for any other C# projects to avoid unnecessary problems. The standard C# naming contains a dot, for example: Ryder.Display
or simply RyderDisplay
.
QUESTION
In the last years i have developed a huge amount of .NET Framework (4.8) Classes with functions and methods for my applications. Most if this apps are commandline apps. A few apps are WPF or Winform-Apps.
Now I want to start with Apps they run in browser. I try to use "Blazor", but the need .NET CORE or .NET STANDARD - and they cann´t use projects/classes from ".NET Framework".
My Question: If i use uno-platform only for UI, can I use/reference to ".NET Framework" Projects oder Libraries? Or have it the same limitation like Razor-Apps?
...ANSWER
Answered 2021-Oct-29 at 09:10Uno Platform in the browser and Blazor share the same underlying .NET WebAssembly runtime, so they have the same limitations in this regard. If you want to use older code you'll need to recompile it, and you won't have access to .NET Framework-only APIs.

ANSWER
Answered 2021-Oct-05 at 09:43After some searching around it turns out that C++ from C++14 on defines two additional delete
operators:
void operator delete ( void* ptr, std::size_t sz ) noexcept; (5) (since C++14)
void operator delete[]( void* ptr, std::size_t sz ) noexcept; (6) (since C++14)
5-6) Called instead of (1-2) if a user-defined replacement is provided, except that it's unspecified whether (1-2) or (5-6) is called when deleting objects of incomplete type and arrays of non-class and trivially-destructible class types. A memory allocator can use the given size to be more efficient. The standard library implementations are identical to (1-2).
(from https://en.cppreference.com/w/cpp/memory/new/operator_delete)
Looking at ArduinoCore-avr's source, these are actually present, and defined as follows:
