NopCommerce ID-Less URL Structure Demystified 💎 The link for my NopLite - nopCommerce Responsive Theme is ✨ :

http://www.pronopcommerce.com/noplite-nopcommerce-responsive-theme

You don't see ANY integer in the URL, but nopCommerce somehow knows how to map from the URL to the appropriate ID. ✅ On the other hand, the nopCommerce 2.65 URL for my NopLite theme would have been 👎🏻 :

http://www.pronopcommerce.com/p/7/noplite-nopcommerce-responsive-theme

Note the '7' somewhere in between the URL, that's the Integer Product ID. 🗃 So the question is, how does nopCommerce 2.70 and 2.80 know the ID without looking the ID❓ https://t.me/pgimg/105 [ Article ] : http://bit.do/nopu 〰〰〰〰〰〰 #AspMvc #Routing #NopCommerce @ProgrammingTip

Mocky 🤖 Mock your HTTP responses to test your REST API. 👾 Mocky is a simple app which allows to generate custom HTTP responses. 🌐 It's helpful when you have to request a build-in-progress WS, when you want to mock the backend response in a singleapp, or when you want to test your WS client. ✅ Is Mocky online❓ Yes, Mocky is online, free and unlimited. 💸 https://t.me/pgimg/104 [ Website ] : mocky.io 〰〰〰〰〰〰 #Mock #Rest @ProgrammingTip

Anatomy of an ASP.NET Identity PasswordHash 🔐 Have you ever looked at a user record in an ASP.NET Identity’s users table and wondered just what is being saved on the PasswordHash column❓ It looks like this (it’s in base64) :

AQAAAAEAACcQAAAAEJSPbbFM1aeXB8fGRV7RRamLpjzktAF7FjwDWtFx35eol4AxN6vm4zWR9EApc7WPsQ

Apart from maybe satisfying your curiosity, what could you benefit from knowing exactly what’s on that seemingly random sequence of characters❓ Well, you could confidently update from different versions of ASP.NET Identity. 🌀 Also, if you ever get tired of ASP.NET Identity for whatever reason, you could move your user accounts to whatever alternative you found that might be better. ✅ Or, you just want to have a simple users’ table and not have to deal with all of what you need to know to make ASP.NET Identity work. 👥 All of this while still being able to move your user accounts to ASP.NET Identity some day if you choose to do so. ♻️ https://t.me/pgimg/103 [ Article ] : http://bit.do/aspidn 〰〰〰〰〰〰 #AspMvc #Identity @ProgrammingTip

Generating Friendly URLs in ASP.NET MVC 🦄 Have a look at the following URL 👀 :

http://www.amazon.com/gp/product/1617292397/ref=s9_psimh_gw_p14_d4_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1&pf_rd_r=0TFM5Q6WM6KD9NPNG9G7&pf_rd_t=36701&pf_rd_p=2079475242&pf_rd_i=desktop

Do you have any idea what the URL is pointing to by just looking at it❓Most likely not. Now look at this one 💎 :

http://www.dpreview.com/articles/9485436827/the-big-beast-hands-on-with-the-panasonic-lumix-dmc-gx8

Any idea❓Well it would seem that it is an article about a hands-on with the Panasonic Lumix DMX-GX8. 🖥 In today’s blog post I would like to demonstrate how to generate “friendly URLs” in your ASP.NET applications. ✅ Friendly not just in the sense that someone can look at it and figure out what the URL is pointing to, but more importantly friendly for search engines. 🌐 https://t.me/pgimg/101 [ Article ] : http://bit.do/aspseo 〰〰〰〰〰〰 #AspMvc #SEO @ProgrammingTip

ASP.NET Core Interview Questions 💼 This post is about ASP.NET Core Interview Questions. ⁉️ These questions are directly tied to ASP.NET Core. ✅ They are not meant to serve as only questions that you would ask a candidate during an interview. ❌ Use these to assess if the candidate has any knowledge about ASP.NET Core. 👓 The questions should serve as guidelines for core ASP.NET Core concepts that candidate should be familiar with. 👪 https://t.me/pgimg/100 [ Article ] : http://bit.do/aspint 〰〰〰〰〰〰 #AspMvc #AspCore #Core #Interview @ProgrammingTip

Q&A: Successful Developer Career Strategies 💎 The field of computer science is huge, far too wide for anyone to master in all areas. 🌍 We all need to make difficult choices about how and where we spend our time. ⏰ It’s often said that in order to be successful in this industry you need to specialize. 🤓 But it’s also often said that you need a wide range of experience. ✅ So what is more important : breadth or depth ⁉️ This is a very difficult question, and is why I asked for the advice of some of the very brightest minds in our industry. 👑 Our expert panel is comprised of the following seven developers 👥 : • Scott Allen • Mark Seemann • Julie Lerman • Kyle Simpson • Troy Hunt • Oren Eini • Cory House https://t.me/pgimg/99 [ Article ] : http://bit.do/qadev 〰〰〰〰〰〰 #QA #Strategy @ProgrammingTip

Use T4MVC to Remove Magic Strings in ASP.NET MVC Apps 🎩 ASP.NET MVC has a fascination with magic strings. ❌ Basically any time you need to specify an action, a view, or controller, you use a magic string ✨ :

return RedirectToAction("Index", "Home", new { id = 4 });

return View("Details");

@Html.ActionLink("Back to details", "Detals", "User", new {id = 12}, new {@class = "backlink"});

@using (Html.BeginForm("Details", "User", FormMethod.Post))

The problem with magic strings is the same problem that ViewBag has ⚠️ : 1️⃣ There's no type checking. 2️⃣ The developer won't catch these errors until runtime, and sometimes not at all. 🔹🔸🔹🔸 T4MVC aims to remove magic strings from MVC and replace them with strongly-typed ActionResults. ✅ It adds a bunch more overloads to methods such as ActionLink(), BeginForm(), and RedirectToAction() so that they can now accept ActionResults as parameters. 🗃 Thereby making them strongly-typed and removing their dependency on magic strings. 💎 Most importantly, it means we can take the above code samples and refactor them to look like this 🤙🏻 :

return RedirectToAction(MVC.Home.Index(4));

return View(MVC.User.Views.ViewNames.Details);

@Html.ActionLink("Back to details", MVC.User.Details(12), new {@class = "backlink"});

@using (Html.BeginForm(MVC.User.Details(), FormMethod.Post))

Architecting Services with Design Patterns 💎 As the number of your services expands you're going to need to start thinking about how to organize them. 🗂 Applying these two design patterns can help, provided you understand all their variations. ✅ With the current set of tools that come with the Microsoft .NET Framework, it's easy to create a service. ⚙️ But it's also easy to create what both Nayaki Nayyar and Benjamin Moreland described as a "junk drawer of services." 👾 If you're going to avoid that as the number of services in your organization increases, then you need to think about your architecture. 🤔 https://t.me/pgimg/95 [ Article ] : http://bit.do/asdp 〰〰〰〰〰〰 #CleanCode #DesignPatterns @ProgrammingTip

ASP.NET MVC Best Practices and Guidelines ✅ While most developers were used to WebForms and Microsoft's stock controls, when developers moved to ASP.NET MVC, a number of developers were shocked because there wasn't enough meat for this to be a full-featured release. 🤓 Some of the guidelines list below are based on my own experiences over the years since 2008. 📆 https://t.me/pgimg/93 [ Website ] : http://bit.do/aspbst 〰〰〰〰〰〰 #AspMvc #CleanCode #BestPractices @ProgrammingTip

Working With Zip Files In ASP.NET MVC 🗂 Since ASP.NET 4.5, zipping and unzipping files can be done with classes from within the .NET framework. 📂 Despite that, nearly all examples that illustrate working with zip files in ASP.NET applications feature third party open source compression libraries. 👾 This short article attempts to correct that by demonstrating the use of the System.IO.Compression classes in an ASP.NET MVC application to ✅ : 1️⃣ Unpack an uploaded zip file 2️⃣ Create one for download https://t.me/pgimg/92 [ Article ] : http://bit.do/aspzip 〰〰〰〰〰〰 #AspMvc #Compression @ProgrammingTip

How we do MVC – View models 👀 The ViewModel is a central aspect of our MVC architecture. 🌞 One of the first dilemmas facing MVC developers is to decide what the “M” in MVC means in ASP.NET MVC. 🤔 In Rails, this is fairly clear, the M is ActiveRecord (by default). 🌍 But in ASP.NET MVC, the “M” is silent❗️ Its out-of-the-box architecture offers no guidelines nor advice on what the M should be. ⚙️ Should it be an entity❓ Data access object❔ DTO❓ Something else❔ https://t.me/pgimg/91 [ Website ] : http://bit.do/mvvm 〰〰〰〰〰〰 #AspMvc #CleanCode #BestPractices @ProgrammingTip

The state of JavaScript in 2017 🔥 A few years back, a JavaScript survey would've been a simple matter. Question 1 : Are you using jQuery❓ Question 2 : Any comments❓Boom, done❗️ But as we all know, things have changed. ✨ The JavaScript ecosystem is richer than ever, and even the most experienced developer can start to hesitate when considering the multitude of options available at every stage. There's data from over 20,000 developers, asking them questions on topics ranging from front-end frameworks and state management, to build tools and testing libraries. ✅ https://t.me/pgimg/90 [ Website ] : https://stateofjs.com 〰〰〰〰〰〰 #JavaScript #Analytics @ProgrammingTip

Automatic ModelState Validation in ASP.NET MVC 🔥 How many times have you seen or written code like this ♻️ :

[HttpPost]
public ActionResult Index(SomeModel model)
{
    if (ModelState.IsValid)
    {
        return View();
    }   

    // do something
    return RedirectToAction("index");
}

Stop repeating ModelState checks in your ASP.NET MVC controller actions. ❌ Wouldn’t it be nice if all we had to do was like this ? ⚡️

[HttpPost]
[ValidateModelState]
public ActionResult Index(SomeModel model)
{
    // if we get here, ModelState is valid
    // save to db etc.
    return RedirectToAction("index");
}

Send ETag headers in ASP.NET Core ✨ ASP.NET Core doesn’t add an ETag header automatically to HTTP responses from MVC action methods or Razor Pages. ❌ We have to implement that ourselves to provide the users with true Conditional GET support that honors the If-None-Match request header. ✅ Wouldn’t it be nice if all we had to do was to register it using app.UseETagger() like this❓ https://t.me/pgimg/88 [ Article ] : http://bit.do/etags 〰〰〰〰〰〰 #AspMvc #AspCore #ETag @ProgrammingTip
