Bypass Authorize Attribute in .Net Core for Release Version

Just add an anonymous filter could do the trick, simple and easy.

   services.AddMvc(opts =>
   {
      opts.Filters.Add(new AllowAnonymousFilter());
   });

As pointed out in the comments, you can create a base class for all your requirement handlers.

public abstract class RequirementHandlerBase<T> : AuthorizationHandler<T> where T : IAuthorizationRequirement
{
    protected sealed override Task HandleRequirementAsync(AuthorizationHandlerContext context, T requirement)
    {
#if DEBUG
        context.Succeed(requirement);

        return Task.FromResult(true);
#else
        return HandleAsync(context, requirement);
#endif
    }

    protected abstract Task HandleAsync(AuthorizationHandlerContext context, T requirement);
}

Then derive your requirement handlers from this base class.

public class AgeRequirementHandler : RequirementHandlerBase<AgeRequirement>
{
    protected override HandleAsync(AuthorizationHandlerContext context, AgeRequirement requirement)
    {
        ... 
    }
}

public class AgeRequirement : IRequrement 
{
    public int MinimumAge { get; set; }
}

And then just register it.

services.AddAuthorization(options =>
{
    options.AddPolicy("Over18",
                      policy => policy.Requirements.Add(new AgeRequirement { MinimumAge = 18 }));
});

You can define your own handler that disables authorization:

public class DisableAuthorizationHandler<TRequirement> : AuthorizationHandler<TRequirement>
    where TRequirement : IAuthorizationRequirement
{
    protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, TRequirement requirement)
    {
        context.Succeed(requirement);

        return Task.CompletedTask;
    }
}

and then register it:

    public void ConfigureServices(IServiceCollection services)
    {
    //...
#if DEBUG
    services.AddTransient<IAuthorizationHandler, DisableAuthorizationHandler<IAuthorizationRequirement>>();
#endif
    //...
    }
