ASP.NET Core 3 and 500.30 In-Process Startup Failure

0

My service targets the following frameworks:

  • Microsoft.AspNetCore.App 3.0.0
  • Microsoft.NETCore.App 3.0.0

Everything runs fine locally. When I deploy to an App Service in Azure, I experience the following error:

500.30 In-Process Startup Failure

Reading the documentation tells me perhaps these frameworks are not on the machine hosting my service. However I checked what frameworks are installed on the machine by running dotnet --info on the App Service's console, giving me the following results:

Clearly both my targeted frameworks exist on the machine.

Here is (partial) proof my files are deployed:

Deployed files for my app service

Here is my start up file (nothing unusual):

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors();
            services.AddControllers();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseCors();

            app.UseRouting();
            app.UseEndpoints(endpoints => {
                endpoints.MapControllers();
            });
        }
    }

What am I doing wrong? Why am I getting this error?

Here are some event logs if they help:

Running the app from Kudu cmd console usually outputs startup errors. Try dotnet MyApp.dll.
