Look at the following code: var x = new Date('2016-01-29T14:00:00'); console.log(x.getTime()); Running it in different browsers is surprising 1454076000000 // Chrome | FF | Opera 1454072400000 // IE | Edge MDN says: The getTime() method returns the numeric value corresponding to the time for the specified date according to universal time. I repeat according to universal time! ECMA Script Spec says: Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC

The Visual Studio Team is in the process of switching the debugging engine (at least since VS 2013). Today I experienced a really scary behavior. Here is a screenshot of the legacy engine and the new one – both failing to show me that the List contains 75 items, but in different ways. Lesson learned: The only thing you can trust is your trace output!

After an Update of Visual Studio 2015 (14) I wanted to use my usual keyboard short cut ([ALT] + [D]) to expand the “Debug”-menu and … Two menu entries listening to [D] now? For this ridiculous amount of 4 (in words four) menu entries? Seriously? Just delete the folder. And voila: Back. Productive. Done. Dear Microsoft, please stop that kind of marketing making developers every day life harder. I know you can do much better!

Junctions are really useful. It pretty easy to create them inside a command shell on windows: But as it is a command inside cmd.exe and not a executable you cannot use mklink from PowerShell without calling cmd.exe BUT: the *New-Item *cmdlet supports options to achieve the same since Windows Management Framework v.5.

Pretty simple with the search and replace of Visual Studio using Regular Expressions: Find what: throw new ArgumentNullException\(\"([a-z|A-Z]*)\"\); Replace with: throw new ArgumentNullException(nameof($1));

Ok, this is kind of a rant post. I acknowledge that Microsoft is really really doing a good job at certain (developer) spots (ASP.NET, Visual Studio, IIS, SQL Server, …). But NOT at the browser developer tools – I’m listing my issues here, hoping the IE-Team will listen and make the world better for everybody. Dev Tools Pinning Location Why can’t I pin the developer toolbar on the right side as in every other browser.

For security reasons request sizes are limited by default. This is configurable in the web.config file through the httpRuntime sections maxRequestLength attribute. The value is an integer and it’s default value is 4096 (KB) and therefor is 4,153,344 bytes or 4 MB. The configured values can easily be read using the .NET configuration API: If an request is larger than this value a HttpException is thrown when the HttpRequest properties Forms, Files or InputStream are accessed.

I do component based development. Meaning I have 30+ repos, builds and each of them has 1-10 projects – The main library project, tests, samples and so on. The news about the support end for the .NET Framework 4, 4.5 and 4.5.1 was the motivation to update ALL of my projects. I know this is not neccessary because… .NET 4.5.2, 4.6 and 4.6.1 are compatible, in-place updates on top of .

Since more than a decade just community (a non commercial organization that I co-founded) organizes the NRW Conf. This year the attendee numbers increased again slightly which means we cannot grow anymore (because of fire prevention the upper limit is fixed) as long as we stay in the same location (die Börse). But the attendees love it and so do we. I’d like to thank all sponsors, attendees, speakers and stuff for making it such a great event!

Last time I was in Poland was 2006 for the Microsoft Technical Summit. This years October I was invited by the amazing Maciej Pilecki and his company DataMaster who organize the .NET Developer Days Poland. They did an amazing event with an international speaker line up. They got two Scotts (Hanselman and Hunter) and even managed to bring me and my former boss Clemens together (warning the distance between our home places is about 60 Km!

It felt great to be and speak at Basta! again. Thanks to the organization and the audience. Here are my slides and samples: Defensive programming, resilience patterns & antifragility http://www.slideshare.net/lennybacon/2015-basta-2015-de-defensive-programming-resilience-patterns-antifragility https://github.com/lennybacon/resilience-patterns-js https://github.com/lennybacon/resilience-patterns-ts JavaScript & Build http://www.slideshare.net/lennybacon/2015-basta-2015-de-javascript-und-build

It had been ten years ago, since I was the last time in the Ukraine. Back then in Kiew I held an architects workshop together with Michael teaching Service Oriented Architectures with the Microsoft .NET Framework 3.0, Windows Communication Foundation (WCF) and Windows Workflow (WF). I can remember that I lost my luggage (bad) and the nice people, good questions and superb feedback we received (definitely good). Nataly Potapova, of Sigma Software, contacted me to ask If I would like to become one of the speakers for the Network conference.

The new framework version is out. As with every new release it seems to me that the search indexes on Microsoft downloads have not been rebuilt yet. So I abuse this blog post and note the download links to myself… Microsoft .NET Framework 4.6 (Offline Installer) for Windows Vista SP2, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2008 SP2 Windows Server 2008 R2 SP1, Windows Server 2012 and Windows Server 2012 R2

IntelliJ has the ability to use Maven as build and project system. The concept of an archetype is a predefined project or project template. When “File | New project” is used to create a new project and “Maven” is selected the following dialog is displayed: IntelliJ comes with a few archetypes but of course custom ones can be added. On the MVN Repository for example several archetypes for Wildfly are available: http://mvnrepository.

Code snippets can be helpful. Otherwise the can lead to code duplicates – so use them with wisely. In JetBrains IntelliJ the code snipptes are called Live Templates. They are stored in files saved in C:\Users\{UserName}\.IntelliJIdea{Version}\config\templates on Windows and ~/.IntelliJIdea{Version}/config/templates on Linux. To create a live template open IntelliJ and open the Settings from the File menu. In the Settings dialog you can use the search text box to quickly access the Live Templates section.

Get the public key for the InternalsVisibleTo attribute from a string name key pair file: Get the public key for the InternalsVisibleTo attribute from a strong named assembly:

I really like FxCop. But in a debugging session it can be useful to save time by temporarily disabling the code analysis. Sadly there is no global switch to turn it off and on again. So here is my approach: Create a new text file in the directory C:\Users\{your user}\Documents\WindowsPowerShell named NuGet_profile.ps1 and add the following code: Restart Visual Studio. Click the menu View | Other Windows | Package Manager Console.

Today I was building a credential store API. One implementation against the Windows Credentials Manager (CredMan), the other one persisting information in a database. Of course the data is not persisted in clear text. I use either the MachineKey functionality or a RSA certificate based encryption. So far so good, but I want the passwords to be secure in memory to. The .NET Framework already has a Type built in for that purpose: SecureString
