Compiler Warning ASPIREBLAZOR001

Version introduced: 13.4

Blazor WebAssembly hosting types and members are for evaluation purposes only and are subject to change or removal in future updates. Suppress this diagnostic to proceed.

This diagnostic warning is reported when using experimental Blazor WebAssembly hosting APIs from the Aspire.Hosting.Blazor integration, including:

• BlazorGatewayExtensions — AddBlazorGateway, AddBlazorWasmApp, AddBlazorWasmProject<TProject>, and WithBlazorClientApp
• BlazorHostedExtensions — client wiring for a hosted Blazor Web App
• BlazorWasmAppResource — the resource type that represents a Blazor WebAssembly app

Example

The following code generates ASPIREBLAZOR001:

AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var gateway = builder.AddBlazorGateway("gateway");

var store = builder.AddBlazorWasmApp("store", "../Store/Store.csproj");

gateway.WithBlazorClientApp(store);

builder.Build().Run();

To correct this warning

Suppress the warning with one of the following methods:

• Set the severity of the rule in the .editorconfig file.

  .editorconfig

  [*.{cs,vb}]
  dotnet_diagnostic.ASPIREBLAZOR001.severity = none

• Add the following PropertyGroup to your project file:

  </PropertyGroup>
