Developer Community System Requirements Compatibility Distributable Code Xamarin Blogs Servicing

Visual Studio for Mac follows the Microsoft Modern Lifecycle Policy, starting with the date the major product version is released to the world (RTW).

Servicing is performed through 'Updates' which are packages of new features and cumulative fixes for existing features in the product.

You are in a 'supported state' as long as:

You are using the latest release of the product distributed via the Stable channel.
You remain licensed to use the product.
Microsoft continues to offer support for this product.

Channels

Visual Studio for Mac offers the option to subscribe to Stable, Beta, and Alpha channels. The Stable channel is the only supported channel.

Beta and Alpha are considered preview channels for customers to provide feedback for and receive early previews of pre-release features that are still under development. Beta and Alpha channels are not supported.

How to Get Updates

Microsoft team add in for mac outlook. You can get updates by following in-product prompts or by downloading the latest from VisualStudio.microsoft.com or My.VisualStudio.com.

If you choose to switch channels to either the pre-release Beta or Alpha channel, then no support is provided on that installation of Visual Studio for Mac.

Support for the Mono Framework

Visual Studio for Mac is created using Mono, an open source development platform based on the .NET Framework sponsored by Microsoft. Our support of Mono extends only to the Visual Studio for Mac product, but not to any projects you might create within Visual Studio for Mac using the Mono Framework.

Example 1: If there is a bug in Visual Studio for Mac resulting from use of the Mono Framework, we may support you with a fix or workaround to get Visual Studio for Mac working again.

Example 2: You are developing an application utilizing the Mono Framework and encounter an issue in Mono which is causing your application to behave in an unexpected fashion. Microsoft will not provide any fixes or workarounds to you or make any fixes to the Mono Framework as a result.

For more assistance with Mono, please visit the Mono Project community landing page.

Components not Covered by Visual Studio Servicing

Visual Studio for Mac includes a collection of compilers, languages, runtimes, environments, and other resources or tools that enable development for many platforms. These components may be installed with Visual Studio for Mac but are subject to their own license and support and lifecycles policies.

In addition to components, Visual Studio for Mac also uses several projects and project item templates. The support for these templates is governed by the component that provides those templates.

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

.NET Core 2.1 is automatically installed when you install Visual Studio for Mac.

Creating an ASP.NET Core app in Visual Studio for Mac

Open Visual Studio for Mac. On the Start Screen, select New Project..

Uninstall Microsoft Visual Studio For Mac

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)

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

Is Microsoft Visual Studio For Mac C++

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:

Microsoft word mac free. 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 app
UseContentRoot(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 both UseKestrel and UseIISIntegration 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 and Configure

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 the app.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 the HelloWorld Controller, and the Index action method.
Add the services.AddMvc(); call to the ConfigureServices 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 (replacing xxxx 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:

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.
