We have tested the VS Code and Android Emulator on t.Having this same problem in Visual Studio for Mac when I go to Tools > Google Emulator Manager. Debugging to the emulator is as simple as selecting one of our device profiles from the debug target dropdown and hitting the play button.In this post, we’ll walk through creating a simple “To Do” application in a future post we’ll add some more advanced PWA features.This video is about Apple MacBook M1 Visual Studio Code and Android Emulator Performance Hindi in India. This alternative is free to use, but it runs only on Windows computers.The Visual Studio Emulator for Android is included when you install Visual Studio to develop for Android, iOS, and Windowsall from one code base using familiar languages such as C, JavaScript, and C++.You’ll need to have version 8.6 Preview 5 and later, and until the full release you’ll need to ensure you have the latest. Creating a new Blazor PWA is especially easy now in Visual Studio for Mac using the latest Blazor project template. (Visual Studio Enterprise) Android SDK: /Users/tom/android-sdk-macosx Supported Android versions: 5.0 (API level 21) 5.1 (API level 22) 6.0 (API level 23) 7.0 (API level 24).We’ll name our application “BlazorPwaTodo”. NET Core Console project by selecting Web and Console > App > Blazor WebAssembly App.Next, you’ll need to configure the new Blazor WebAssembly (often abbreviated as WASM) application. From here we will create a. Make your voice heard by filing bug reports or sharing feature suggestions on Developer Community. If you already have Visual Studio open, you could also use the ⇧⌘N shortcut to open the new project dialog.Which means Visual Studio 2019 for Mac is full of features that were inspired by YOU From XAML Hot Reload to faster Android build and deployment times. After launching Visual Studio for Mac you’ll see the dialog below, click New to begin creating the project.Name the component’s file Todo.razor.Use the following initial markup for the Todo component: "/todo"The first line of this template defines a route template, so browsing to “/todo” will resolve to this Todo component.Next, we’ll add the Todo component to the navigation bar. Right-click the Pages folder and select Add > New Item > Razor Component. Adding a Todo Razor ComponentWe’re going to build a simple To Do application, so we’ll start by creating a new page to view our list. Second, using an ASP.NET Core Hosted site makes it easier to run a published version of the app in your local developer environment. First, because we plan to integrate some backend services in the future. Dotnet new blazorwasm -o BlazorPwaTodo -pwa -hostedNote: We’re selecting the “ ASP.NET Core Hosted” option for two reasons.
![]() Visual Studio Android Emulator Code Base UsingName the new class file TodoItem.cs and enter the following code: public class TodoItemReturn to the Todo.razor component and add the following code: (var todo in ) Let’s take a look at what this code is doing: Right-click the Blazor.PwaTodo.Shared project and select Add > New Class. Since we’re using an ASP.NET Core hosted template and will probably include some back-end APIs later, we’ll put that class in Shared project to make it available for use in our server application as well. Clicking the Todo link in the navigation shows our new page with the Todo heading, ready for us to start adding some code.Let’s create a simple class to represent a todo item. If you’d like a more thorough explanation, there’s an in-depth walkthrough of this Todo example in the Blazor documentation.Run the application (again, by using the Run > Start Without Debugging command in the menu) and verify that you can add new items to the list.So far, our Todo application only allows adding new items to the list with no support for marking them complete. The AddTodo method checks to make sure that text has been entered, then adds a new item to the list and clears the input to allow adding another item.Note: This explanation is condensed for brevity. We’re using the button’s attribute to call the AddTodo method. The input element has a a corresponding button to allow adding new items to the list. We have an input element that is bound to a string property named newTodo. We’re iterating over the list of items using a foreach loop inside the ul element. Blazor WebAssembly is a standards-based client-side web app platform, so it can use any browser API, including PWA APIs required for the following capabilities: Every time you’ve been running this application, it’s actually been running with PWA support due to using the PWA template.A Progressive Web Application (PWA) is a Single Page Application (SPA) that uses modern browser APIs and capabilities to behave like a desktop app. Leave the application running when you’re done testing, as we’ll be using the running application in the next section.Now that we’ve built a basic application, we can start taking advantage of the PWA features. Update the h3 element with this code: Todo => !todo.IsDone))Run the application to see it in action. (var todo in todos)And finally, to verify that these values are bound, we’ll update the page header to show the number of items that are not yet complete. When your application is running, you’ll see an installation prompt in the browser. Automatically updating in the background.We’ll look at two of these features in this post, then dig into some more advanced features in a future post.First, let’s look at installation. Receiving push notifications from a backend server, even while the user isn’t using the app. Being launched from the host’s operating system start menu, dock, or home screen. Running in its own app window, not just a browser window. The browser automatically downloads and caches all the resources required to operate offline.However, offline support would interfere with local development since you might be viewing cached offline files when you make updates. A user must first visit the app while they’re online. Testing mobile PWA installation and offline supportBy default, apps created using the PWA template option have support for running offline. We’ll dig into that customization in the next post. Launch the server application using this command:This launches the published application running on localhost port 5001. The default should be bin/Release/netcoreapp3.1/publish.Open a terminal and navigate to the publish directory – you can use Visual Studio for Mac’s integrated terminal if you’d like. You can leave the default folder name but be sure to note it. Right-click on the BlazorPwaTodo.Server application and select Publish > Publish to Folder. The Android emulator does provide a local loopback on 10.0.0.2, but it doesn’t trust the ASP.NET Core HTTPS dev certs, which causes some additional setup. For more background on why we’re setting the host header, see this blog post by Jerrie Pelser.Note: There are several different options for pointing a mobile emulator at your development website, but they all can carry some unexpected complications. My favorite way to handle that is by using the popular ngrok tool. After installing ngrok, launch it using the following command: ngrok http -host-header=”localhost:5001”You should see ngrok spin up and provide a temporary public https endpoint we can use for testing. The easiest way to do this is by using the Network tab in browser tools to simulate offline mode, as shown below.But let’s make this a bit more of a challenge, and test this out in the mobile emulator! In order to do that, we’ll need our mobile browser to be able to connect to our published site. You should see the website, as well as a prompt to install the application locally. I’m using the Pixel 2 Pie 9.0 image.Browse to the public HTTPS endpoint provided by ngrok. If you don’t already have an Android device configured, create one by clicking the New Device button. So, in my experience so far, ngrok is the quickest and simplest way to do a quick PWA / mobile test.Now that we’ve got our site ready for testing on Using Visual Studio for Mac, we can launch an Android emulator using the Tools > Device Manager menu (assuming you’ve installed the Android workload).
