Blazor.BFF.AzureAD.Template 1.0.4

Blazor.BFF.AzureAD.Template

Change log

This template can be used to create a Blazor WASM application hosted in an ASP.NET Core Web app using Azure AD and Microsoft.Identity.Web to authenticate using the BFF security architecture. (server authentication) This removes the tokens form the browser and uses cookies with each HTTP request, response. The template also adds the required security headers as best it can for a Blazor application.

Features

• WASM hosted in ASP.NET Core 6
• BFF with Azure AD using Microsoft.Identity.Web
• OAuth2 and OpenID Connect OIDC
• No tokens in the browser

Using the template

dotnet new -i Blazor.BFF.AzureAD.Template
