.net-core

问题 I'm using Visual Studio 2019 to publish a self contained .net core 2.1 app. Many files are emitted during the publishing (application files as well as core libraries).

As recommended in the Microsoft Migration guide I have done the changes. Also, as most of my enums need to be serialized as String I have configured my Startup.cs ConfigureServices to use the JsonStringEnumConverter globally. public void ConfigureServices(IServiceCollection services) { // lines omitted for brevity services.AddControllers()

问题 Following Eric Lippert's post years back on precision of DateTime , I ran his test on .netcore and .NET Framework 4.5.2, on the same machine with Windows 10. var n = 1000; int i = 0; long[] diffs = new long[n]; while (i++ < n-1) { if (ticks != DateTime.Now.Ticks) { var newTicks = DateTime.UtcNow.Ticks; var diff = newTicks - ticks; diffs[i] = diff; ticks = newTicks; } } foreach (var d in diffs) { if (d == 0) Console.WriteLine("same"); else Console.WriteLine(d); } The result on .NET framework 4
