Blazor is a web framework for building web UI components (Razor components) that can be hosted in different ways. Razor components can run server-side in ASP.NET Core (Blazor Server) versus client-side in the browser on a WebAssembly-based .NET runtime (Blazor WebAssembly, Blazor WASM). You can also host Razor components in native mobile and desktop apps that render to an embedded Web View control (Blazor Hybrid). Regardless of the hosting model, the way you build Razor components is the same. The same Razor components can be used with any of the hosting models unchanged.

With the Blazor Server hosting model, components are executed on the server from within an ASP.NET Core app. UI updates, event handling, and JavaScript calls are handled over a SignalR connection using the WebSockets protocol. The state on the server associated with each connected client is called a circuit. Circuits aren't tied to a specific network connection and can tolerate temporary network interruptions and attempts by the client to reconnect to the server when the connection is lost.

In a traditional server-rendered app, opening the same app in multiple browser screens (tabs or iframes) typically doesn't translate into additional resource demands on the server. For the Blazor Server hosting model, each browser screen requires a separate circuit and separate instances of server-managed component state. Blazor considers closing a browser tab or navigating to an external URL a graceful termination. In the event of a graceful termination, the circuit and associated resources are immediately released. A client may also disconnect non-gracefully, for instance due to a network interruption. Blazor Server stores disconnected circuits for a configurable interval to allow the client to reconnect.

The Blazor WebAssembly hosting model runs components client-side in the browser on a WebAssembly-based .NET runtime. Razor components, their dependencies, and the .NET runtime are downloaded to the browser. Components are executed directly on the browser UI thread. UI updates and event handling occur within the same process. Assets are deployed as static files to a web server or service capable of serving static content to clients.

Blazor web apps can use the Blazor WebAssembly hosting model to enable client-side interactivity. When an app is created that exclusively runs on the Blazor WebAssembly hosting model without server-side rendering and interactivity, the app is called a standalone Blazor WebAssembly app.

When a standalone Blazor WebAssembly app uses a backend ASP.NET Core app to serve its files, the app is called a hosted Blazor WebAssembly app. Using hosted Blazor WebAssembly, you get a full-stack web development experience with .NET, including the ability to share code between the client and server apps, support for prerendering, and integration with MVC and Razor Pages. A hosted client app can interact with its backend server app over the network using a variety of messaging frameworks and protocols, such as web API, gRPC-web, and SignalR (Use ASP.NET Core SignalR with Blazor).

A Blazor WebAssembly app built as a Progressive Web App (PWA) uses modern browser APIs to enable many of the capabilities of a native client app, such as working offline, running in its own app window, launching from the host's operating system, receiving push notifications, and automatically updating in the background.

Components rendered for the Blazor Server hosting model have direct access to server and network resources where the app is executing. Because components hosted using Blazor WebAssembly or Blazor Hybrid execute on a client, they don't have direct access to server and network resources. Components can access server and network resources indirectly via protected server-based APIs. Server-based APIs might be available via third-party libraries, packages, and services. Take into account the following considerations:

Rendering components from the server reduces the app payload size and improves initial load times. When a fast initial load time is desired, use the Blazor Server hosting model or consider static server-side rendering.

Standalone Blazor WebAssembly apps built as Progressive Web Apps (PWAs) and Blazor Hybrid apps can run offline, which is particularly useful when clients aren't able to connect to the Internet. Components rendered for the Blazor Server hosting model fail to run when the connection to the server is lost. If an app must run offline, standalone Blazor WebAssembly and Blazor Hybrid are the best choices.

Static site hosting is possible with standalone Blazor WebAssembly apps because they're downloaded to clients as a set of static files. Standalone Blazor WebAssembly apps don't require a server to execute server-side code in order to download and run and can be delivered via a Content Delivery Network (CDN) (for example, Azure CDN).

Components rendered using the Blazor WebAssembly or Blazor Hybrid hosting models execute on clients and thus offload processing to clients. Components rendered for the Blazor Server hosting model execute on a server, so server resource demand typically increases with the number of users and the amount of processing required per user. When it's possible to offload most or all of an app's processing to clients and the app processes a significant amount of data, Blazor WebAssembly or Blazor Hybrid is the best choice.

The gRPC template is configured to use Transport Layer Security (TLS). gRPC clients need to use HTTPS to call the server. The gRPC service localhost port number is randomly assigned when the project is created and set in the Properties\launchSettings.json file of the gRPC service project.

Visual Studio starts IIS Express and runs the app. The address bar shows localhost:port# and not something like example.com. That's because localhost is the standard hostname for the local computer. Localhost only serves web requests from the local computer. When Visual Studio creates a web project, a random port is used for the web server.

Now, the problem (if you haven't guessed already). I can't seem to get my new shiny SignalR client to work with my old Framework SignalR server. The error message is very specific when the call to SignalR is made: 17dc91bb1f
