How to stay logged in during development of a Blazor Web Assembly app that uses Azure AD B2C for authentication

Question

I am developing a Blazor Web Assembly app in Visual Studio that uses Azure AD B2C for authentication. It is all setup and working well except that developing is a chore because each time I want to launch the debugger and open the browser to review my work I am required to login in again to view pages that require authentication. This is a time consuming and annoying step that I would hope to avoid.

Ideally there would be a way to stay logged in between debug browser sessions launched from Visual Studio.

I have searched for the answer on the web with not luck yet. Anyone have any ideas on how to do this?

Answer 1

In Program.cs, set MsalCacheOptions.CacheLocation to "localStorage"

Example:

    builder.Services.AddMsalAuthentication(options =>
    {
        // Keeps logged in between debugging sessions
        options.ProviderOptions.Cache.CacheLocation = "localStorage";

        // Set up other options
        ...
    });
