How can i download for macOS?
Error: SysAllocStringLen not found
Submitted by olive ridley on Sun, 02/16/2020 - 04:24
So far so good. I installed Eclipse (which I haven't used for quite a while), .Net core, and Acute on my Linux Ubuntu without problems. My Hello World program works. But when I go to debug my Hello World program (debug as .Net Core), having added some trivial and unnecessary computations, I get Error: SysAllocStringLen not found while the program otherwise executes normally.
How can I create a window form class?
Submitted by Carlos Pardo on Tue, 07/16/2019 - 17:46
I've installed C#Acute complement, I've created a new Console Application (C#), but now I need to create a Window Form class!
I don't see that option when I am creating a new project. Which option should I choose?
Thanks,
Carlos

You'll need to update your dotnet-sdk to 3.0 or higher. For it to show more templates.
What is the perspective for C#?
Submitted by Tony Esposito on Thu, 08/09/2018 - 09:30
I can install w/o errors but what perspective do I choose? I don't see a C# perspective.

In reply to What is the perspective for C#? by Tony Esposito
There is no specific perspective for C#. Everything you need is accessible from the usual perpecitves like the "Resources" one. You can open additional views you like for C# in any perspective with Window > Show View.

Hi. Thanks for your interest.
The marketplace comments aren't a proper and efficient place to provide user assistance. Please open issues against the project instead https://github.com/eclipse/aCute/issues/ to get assistance from contributors.

It is my understanding that this does not support .Net above version 3.1. If so then this is a highly relevant question. The version(s) of .Net supported by this should be specified, especially if no recent version is supported.
