Each time dependencies change, run createdevcontainer.sh to create a Docker image and container.First, install a GUI LDAP frontend locally on the client side. Download the Linux version of CLion. It uses XQuartz, a version of the X Window System that runs on macOS, along with socat. The following steps get the CLion IDE running in a Docker container created during the project's build process.
![]() Docker And Gui Applications Download The LinuxMy empty Mac app is started as shown below.This was simple. I would like to show how easy this is with Visual Studio for Mac 2019 (version 8.4).I open my Visual Studio for Mac 2019 and start new Mac/Cocoa App/C#, e.g.:Then, I configure Visual Studio project and solution names, location and if I will use git on my project.Next step is entering application-related and basic data for newly created application.Everything is ready, I just build and run the project. Empty Mac applicationFor start, I will create empty Cocoa app with C#. At the end, I will show how to extend this basic approach to a more complex scenario. Then I will put some GUI elements and wire-up control properties and events with a C# logic. Under the hood, accessing native macOS APIs is the same as with Objective-C or Swift development.I will start with empty macOS Cocoa/C# application. Long story short: I save storyboard, return to Visual Studio, compile and run. For the purpose of this experiment, I add one Button and one Label control. For more check out this link. I can basically use all controls in the Apple AppKit framework. I do this by clicking Library button (menu: View->Show Library, shortcut: cmd+shift+L), selecting desired control and drag it to the View surface of selected ViewController. Because, I’ll do some drag-and-drooping it’s very convenient to properly arrange windows to be visible on my desktop. Then I rearrange windows as shown on bottom picture. First, I open my Main.storyboard in Xcode (check previous section how to to this). NET developers: EventHandlers and PropertiesNow, it’s time to wire-up controls with C# code. Actions and Outlets – or for. Next thing I’ll do is to put some logic into my application. Check image below for more visual representation. Generated code is link between C# code and GUI elements.If I want to execute code in my button eventhandler I simply extend TestButtonClicked event handler and set property to exposed label. Check image below for more info.If everything is ok, I have this definition in my ViewController header file.When I save everything, close Xcode and return to Visual Studio for Mac, I can see that VS for Mac generated some code. When connection popup is displayed I just need to define what kind of connection I am creating: Action (eventhandler) or Outlet(property).I do similar with my label, except here I select Outlet in my connection popup. Middle sections depicts Main.storyboard GUI designer.When I have everything on place I select button control, hold down ctrl button on my Mac keyboard and drag to my ViewController.h file, as marked below. Mac storage cleaner mrFirst, I fine-tuned GUI and then wire up native controls Actions and Outlets with C# code. I would not go into to much details, I simply used methodology described in previous chapters. Simple macOS application – symmetric encryption and hash function in C#.To show a little more complex situation, I implement the same application as I did for Blazor in my blog post entitled Blazor, run C# code inside web browser. In this section I wired-up GUI elements with C# code behind logic. Next picture shows my test application in action.That’s it. Applications and scenarios can be a lot more complex, but the basic approach how to develop macOS apps with C# is as shown in this blog post. For me this is really awesome.To summarize, I demonstrated how to create simple macOS Cocoa application with C# and Xamarin.Mac. This is really something: executing same code inside Web browser with WebAssembly or in macOS Cocoa application. ![]() Technically speaking, I am accessing and using the same underlying APIs. Now, I can reuse C# knowledge and create macOS desktop apps similar as Swift or Objective-C developers. NET Developer – this is very interesting technology. After a while, Visual Studio for Mac, Xcode and a little bit of practice produced satisfying development experience.I know that C# with Xamarin.Mac is not mainstream macOS desktop development, but for me –.
