Securing Blazor WebAssembly with Identity Server 4

The new Blazor WebAssembly 3.2.0 includes support to client side authentication, which makes relatively simple to implement OpenID Connect and OAuth2 in your single page application.

Using a Self-Signed Certificate for IdentityServer4 in Azure App Service

When we create a Blazor WebAssembly project with Default Authentication, it is configured with IdentityServer4 (IS4).

gRPC for WCF Developers

Similarity to WCF Although the implementation and approach are different for gRPC, the experience of developing and consuming services with gRPC should be intuitive for WCF developers.
