May 13, 2017 Visual Studio 2017 for Mac was launched at MS Build 2017 with many fresh and exciting features for Visual Studio developers using Mac machines. Mac OS users can build apps for mobile, web, and cloud with Xamarin and.NET Core, and games with Unity using Visual Studio.
There are many alternatives to Microsoft Visual Studio for Mac if you are looking to replace it. The most popular Mac alternative is Visual Studio Code, which is both free and Open Source.If that doesn't suit you, our users have ranked more than 100 alternatives to Microsoft Visual Studio and many of them are available for Mac so hopefully you can find a suitable replacement. However, Visual Studio just hangs and never seems to actually install the app onto the emulator. After a while if I click on the emulator to view the apps, i get a black screen in the emulator. I can stop the build / deployment and Visual Studio is responsive. Here is a similar post as to what is happening to me.
To start developing native, cross-platform .NET apps on macOS, install Visual Studio 2019 for Mac following the steps below.
The Visual Studio for Mac editor supports powerful built-in refactoring options such as Extract Method and Rename, accessible via the Quick Actions menu. Integrated Source Control Manage your code in Git or SVN repos hosted by any provider, including GitHub and Azure DevOps.

-->Visual Studio for Mac makes it easy to develop your app's service with its support for the latest ASP.NET Core Web development platform. ASP.NET Core runs on .NET Core, the latest evolution of the .NET Framework and runtime. It's been tuned for fast performance, factored for small install sizes, and reimagined to run on Linux and macOS, as well as Windows.
Installing .NET Core
Visual Studio For Mac Tutorial
.NET Core 3.1 is automatically installed when you install Visual Studio for Mac. For more information about versions of .NET Core supported in Visual Studio for Mac see .NET Core Support.
Creating an ASP.NET Core app in Visual Studio for Mac
Open Visual Studio for Mac. On the Start Screen, select New Project...
This will display the New Project dialog, allowing you to select a template to create your application.
There are a number of projects that will provide you with a pre-built template to start building your ASP.NET Core Application. These are:
- .NET Core > Empty
- .NET Core > API
- .NET Core > Web Application
- .NET Core > Web Application (Model-View-Controller)
- .NET Core > Blazor Server App
- .NET Core > Blazor WebAssembly App
Select the ASP.NET Core Empty Web Application and press Next. Give the Project a Name and press Create. This creates a new ASP.NET Core app. In the solution pad's left pane, expand the second arrow and then select Startup.cs. It should look similar to the image below:
The ASP.NET Core Empty template creates a web application with two default files: Program.cs and Startup.cs, which are explained below. It also creates a Dependencies folder, which contains your project's NuGet package dependencies such as ASP.NET Core, the .NET Core framework, and the MSBuild targets that build the project:
Program.cs
Open and inspect the Program.cs file in your project. Notice that several things are happening in the
Main
method – the entry into your app:An ASP.NET Core app creates a web server in its main method by configuring and launching a host via an instance of
WebHostBuilder
. This builder provides methods to allow the host to be configured. In the template app the following configurations are used:.UseStartup<Startup>()
: Specifies the Startup class.
However, you can also add additional configurations, such as:
UseKestrel
: Specifies the Kestrel server will be used by the appUseContentRoot(Directory.GetCurrentDirectory())
: Uses the web project's root folder as the app's content root when the app is started from this folder.UseIISIntegration()
: Specifies that the app should work with IIS. To use IIS with ASP.NET Core bothUseKestrel
andUseIISIntegration
need to be specified.
Startup.cs
The Startup class for your app is specified in the
UseStartup()
method on the CreateWebHostBuilder
. It is in this class that you will specify the request handling pipeline, and where you configure any services.Open and inspect the Startup.cs file in your project:
This Startup class must always adhere to the following rules:
- It must always be public
- It must contain the two public methods:
ConfigureServices
andConfigure
The
ConfigureServices
method defines the services that will be used by your app.The
Configure
allows you to compose your request pipeline using Middleware. These are components used within an ASP.NET application pipeline to handle requests and responses. The HTTP pipeline consists of a number of request delegates, called in sequence. Each delegate can choose to either handle the request itself, or pass it to the next delegate.You can configure delegates by using the
Run
,Map
, and Use
methods on IApplicationBuilder
, but the Run
method will never call a next delegate and should always be used at the end of your pipeline.The
Configure
method of the pre-built template is built to do a few things. First, it configures an exception handling page for use during development. Then, it sends a response to the requesting web page with a simple 'Hello World'.This simple Hello, World project can run now without any additional code being added. To run the app, you can either select which browser you want to run app the app in using the dropdown right of the Play button, or simply hit the Play (triangular) button to use your default browser:
Visual Studio for Mac uses a random port to launch your web project. To find out what port this is, open the Application Output, which is listed under View > Pads. You should find output similar to that shown below:
Once the project is running, your default web browser should launch and connect to the URL listed in the Application Output. Alternatively, you can open any browser of your choice, and enter
http://localhost:5000/
, replacing the 5000
with the port that Visual Studio output in the Application Output. You should see the text Hello World!

Adding a Controller
ASP.NET Core Apps use the Model-View-Controller (MVC) design pattern to provide a logical separation of responsibilities for each part of the app. MVC consists of the following:
- Model: A class that represents the data of the app.
- View: Displays the app's user interface (which is often the model data).
- Controller: A class which handles browser requests, responds to user input and interaction.
For more information on using MVC refer to Overview of ASP.NET Core MVC guide.
To add a controller, do the following:
- Right-click on the Project name and select Add > New Files. Select General > Empty Class, and enter a controller name:
- Add the following code to the new controller:
- Add the
Microsoft.AspNetCore.Mvc
dependency to the project by right-clicking the Dependency folder, and selecting Add Package.... - Use the Search box to browse the NuGet library for
Microsoft.AspNetCore.Mvc
, and select Add Package. This may take a few minutes to install and you may be prompted to accept various licenses for the required dependencies: - In the Startup class, remove the
app.Run
lambda and set the URL routing logic used by MVC to determine which code it should invoke to the following:Make sure to remove theapp.Run
lambda, as this will override the routing logic.MVC uses the following format, to determine which code to run:/[Controller]/[ActionName]/[Parameters]
When you add the code snippet above, you are telling the app to default to theHelloWorld
Controller, and theIndex
action method. - Add the
services.AddMvc();
call to theConfigureServices
method, as illustrated below:You can also pass parameter information from the URL to the controller. - Add another method to your HelloWorldController, as illustrated below:
- If you run the app now, it should automatically open your browser:
- Try to browse to
http://localhost:xxxx/HelloWorld/Xamarin?name=Amy
(replacingxxxx
with the correct port), you should see the following:
Troubleshooting
If you need to install .NET Core manually on Mac OS 10.12 (Sierra) and higher, do the following:
Visual Studio For Mac Os
- Before you start installing .NET Core, ensure that you have updated all OS updates to the latest stable version. You can check this by going to the App Store application, and selecting the Updates tab.
- Follow the steps listed on the .NET Core site.
Make sure to complete all steps successfully to ensure that .NET Core is installed successfully.
