Enable Sentry on certain environments

I want to log to Sentry only when the environment is set to production, but with this code all exceptions are logged to Sentry in any environment… What am I missing?

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseSentry(options =>
                {
                    var env = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");

                    if (env == "Production")
                    {
                        options.Dsn = "DNS Key Here";
                        options.Environment = env;
                        options.IncludeRequestPayload = true;
                        options.IncludeActivityData = true;
                    }
                })
                .UseStartup<Startup>();

Exception

        public virtual Task<List<TEntity>> GetAllAsync()
        {
            throw new InvalidOperationException();
            return this.context.Set<TEntity>().ToListAsync();
        }

And it was logged… I tried to implement something similar with a middleware in Configure method on Startup class but with no success.

Thanks in advance!

Not setting the DSN means the SDK cannot initialize itself. Even if you did call Init or AddSentry. For ASP.NET Core and the other integration, such configuration flag exist: InitializeSdk. If you set it to false, even if the DSN is available, the integration will not attempt to initialize the SDK.

So unless you call SentrySdk.Init yourself, the SDK will be disabled.

Wouldn’t be good to have a configuration option, something like “Enabled”: true/false? Or is not setting DSN proper way how to disable sentry in appsettings?
