Serilog.Enrichers.AzureClaims and Serilog.Enrichers.Claims

Enriches Serilog events with information from the ClaimsPrincipal.

Install the Serilog.Enrichers.AzureClaims NuGet package
Install the Serilog.Enrichers.Claims NuGet package

Install-Package Serilog.Enrichers.AzureClaims
Install-Package Serilog.Enrichers.Claims

Then, apply the enricher to your LoggerConfiguration:

Log.Logger = new LoggerConfiguration()
    .Enrich.WithUpn()
    .Enrich.WithDisplayName()
    .Enrich.WithTenantId()
    .Enrich.WithObjectId()
    .Enrich.WithAppId()
    .Enrich.WithCustomClaim("AnyExistingClaim") // Available from Serilog.Enrichers.Claims
    // ...other configuration...
    .CreateLogger();

Installing into an ASP.NET Core Web Application

The IHttpContextAccessor singleton should be registered, but is not required for these nugets to run. The enrichers have access to the requests HttpContext to extract the data. This is what your Program class should contain in order for this enricher to work as expected:

// ...
using Serilog;

var builder = WebApplication.CreateBuilder(args);

builder.Logging.AddSerilog(new LoggerConfiguration()
    .Enrich.WithUpn()
    .Enrich.WithDisplayName()
    .Enrich.WithTenantId()
    .Enrich.WithObjectId()
    .Enrich.WithAppId()
    .Enrich.WithCustomClaim("AnyExistingClaim")
    .CreateLogger());

var app = builder.Build();
app.UseSerilogRequestLogging();
