Azure Web App failing to start after adding Microsoft.Identity.Web reference (Could not load file or assembly 'Microsoft.IdentityModel.Logging))

Question

Azure Web App failing to start after adding Microsoft.Identity.Web reference to a ASP.NET Core 7 webapi. (Also using NSwag.) Any ideas welcome!

Program.cs:

using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.Identity.Web;

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
        .AddMicrosoftIdentityWebApi(options =>
        {
            builder.Configuration.Bind("AzureAdB2C", options);

            options.TokenValidationParameters.NameClaimType = "emails";
        },
   options => { builder.Configuration.Bind("AzureAdB2C", options); });

Exception message is:

Answer 1

Bit embarrassing this. I never mentioned my deployment pipeline. Bitbucket Pipeline. The dependencies are cached and if you change them you need to manually clear the cache. I didn't, hence the exception.

Leaving this here as it might help someone else.

Thanks for you help,
