Intro to UWP (Universal Windows Platform) Apps in C#

You may have heard about Universal Windows Platform Applications, also known as UWP applications and wondered what they are. In this video, I am going to introduce the topic of UWP and show you how to get started building your own applications using this framework. Along the way, we will talk about when you would build a UWP app, what pitfalls to avoid, and how you can get up to speed faster.

What do you think about UWP: Does it have future? Is it dead? Should we instead stick with WPF?

[@IAmTimCorey]

Here are my thoughts: kzbin.info/www/bejne/r6KTlYahdpappq8 In genreal, none of these are dead but I'm not a huge fan of UWP.

[@gatep5]

Stick with WPF, or do some Xamarin Forms if you haven’t already.

[@richardalbury]

Back when Windows Phone/Windows 10 Mobile was a thing, UWP was interesting because of the promise of having an app run on phones, tablets, and desktops. Phones are gone, and Windows 10 runs WPF and WinForms apps on tablets and desktops, so... ¯\_(ツ)_/¯ Look on Dice or some other job site for UWP listings versus WPF or Xamarin: that should also give you an idea.

[@sent4dc]

No, yes and no. Think about it. If you code something in pure UWP, it will run only on Windows 10. (OK, on hologram and Xbox as well, but let's be realistic, what app will run on all three of them :) So I doubt that any self-respecting developer will want to limit his choices like that. What I would suggest is coding a normal desktop application and then convert it to UWP: developer.microsoft.com/en-us/windows/bridges/desktop/ I personally code my apps in C++ and then convert them to UWP, but you can use .NET and WebForms, etc. There are quite a few gotchas (rules) that you need to follow to be able to convert them, but all-in-all, if it succeeds, in the end you will have a working desktop app (that in theory can run on anything from Windows XP and up) and you can use UWP infrastructure to post your converted UWP app in the Windows Store. (And get maybe 2 or 3 extra downloads a month ... 'cause let's face it, Windows Store for now is only good for growing crickets.)

[@williamscsharpwalkthroughs4316]

@@gatep5 Indeed, WPF seems to be a tried-and-true solution and the choice go-to for many Windows Desktop developers. However I think one of the biggest attractions towards UWP is its deployment options. The integrated Windows Store deployment functionality I think gives it an edge over WPF- where in my experience- I've used utilities such as Inno Setup to create MSI/EXE files, or the WIndows Desktop Bridge; If you're not deploying your application, then it's just sitting there on your PC. Nevertheless, I do prefer WPF because of its richness, but tech is progressing-- I think its worth-while for any Windows developer to at least be aware of UWP and better still somewhat capable to develop on the platform.

I don't have a book to recommend. The way I would suggest is to go through the wizard and add just one item. Read the code, figure out how it works, then recreate it from scratch.

[@lokigaming459]

Alright Tim. I have a question (maybe a couple) that I'd like your feedback. I'm looking to make a project/inventory manager app that a new project gets added to my server (will call it a sub server, give a sec and you'll see why) that takes a folder from a network drive (part of the main and existing server), this would house pdfs and such, and copy the fold to its own harddrive. Then the stations would log in and pull a copy from the sub server. What are your thoughts on what to use? I have already done research but wanted your opinion as well.

[@IAmTimCorey]

You want one central app to pull the files from the machines of the sub-servers? That sounds like a Worker Service as the main service. Unless it needs a UI, it can just sit in the background and do its thing on a schedule.

Hello Tim. I understood that windows 7 end of (support) life was 14 Jan 2020. I think there is a very low % of windows 8.1 out there; hence, most developers can gamble that the majority of windows users are on windows 10. UWP seems a bit like Windows Flow or Microsoft Power Automate, would you agree?

[@IAmTimCorey]

I understand the basic thought, but this isn't as clear cut as you would hope. Not everyone follows the Microsoft support. For instance, banks and hospitals are notorious for being very far behind the curve. The government is also usually well behind the curve. The slowness to adopt in these areas usually is because of security (a new OS needs to be thoroughly vetted for safety reasons) and compatibility (all of the apps also need to be able to run on the new OS and need to be vetted all over again). So if you are building apps that target any of those markets, you are less likely to be able to use UWP at all. Home users are a mixed bag. While they are more likely to have Windows 10 (because they bought a PC in the past few years), they are less likely to know if the updates stop working (virus, poor configuration, etc.) Small businesses tend to try to make their money last longer, so they don't upgrade as often (and they use older apps that might not support the newest OS). At the end of the day, it all depends on your market. You can't just assume that even the general numbers apply to your audience. And those general numbers are still not really in favor of Windows 10. As of January, 2020, Windows 10 had a 57% market share, but Windows 7 had a 25% market share: www.netmarketshare.com/operating-system-market-share.aspx?options=%7B%22filter%22%3A%7B%22%24and%22%3A%5B%7B%22deviceType%22%3A%7B%22%24in%22%3A%5B%22Desktop%2Flaptop%22%5D%7D%7D%5D%7D%2C%22dateLabel%22%3A%22Custom%22%2C%22attributes%22%3A%22share%22%2C%22group%22%3A%22platformVersion%22%2C%22sort%22%3A%7B%22share%22%3A-1%7D%2C%22id%22%3A%22platformsDesktopVersions%22%2C%22dateInterval%22%3A%22Monthly%22%2C%22dateStart%22%3A%222020-01%22%2C%22dateEnd%22%3A%222020-01%22%2C%22segments%22%3A%22-1000%22%7D

[@charlesbyrneShowComments4all]

We have gone past windows support dates on many occasions because of applications that our organization runs that cannot upgrade. What types of apps? Well apps with support contracts that use earlier versions of sql that haven't been upgraded, bridge and middle ware apps that may use specific supported drivers for high end scanners and expensive mail sorters etc. For a document work flow application we literally had to hold off then finally jump 6-7 versions and upgrade from sql 2005 then 2012 then upgrade 2 more versions (64 bit win 8 then win 10) and finally sql 2016, but only after we upgraded from Oracle 10g to 12c and I think Mulesoft was about the only thing that didn't get upgraded. These integrated apps are used heavily by our call center, licensing, accounting, enforcement and legal and would shut down our call center and other sectors if these apps couldn't communicate and work flow items. The Win XP to Win 7 upgrade was a nightmare, windows 7 will be missed, but the upgrade to 10 was not as bad. We skipped 8 since some of the LTS contracts wouldn't support the Client apps on Win 8 without additional costly fees. On the bright side the OS and server upgrades are getting smoother since and not as costly which benefits the taxpayers (state government), but we still wince when Microsoft, Oracle, and various vendors decide to force upgrades. The lawmakers at the budget requests always ask why and didn't we just upgrade software. If they only knew.

Hey, Corey, thanks. Couple questions: 1. Do know if there's a tool like dnSpy but for UWP apps? 2. Is there a service to localize (translate) resources for your app?

[@IAmTimCorey]

dnSpy does work on UWP apps. As for a service to translate your apps, I'm not sure what you mean. If you mean automatically, I'm not sure but even if there is, it won't be perfect. If you mean a paid service, yes, there are services out there to localize your applications.

[@sent4dc]

@@IAmTimCorey it does? Are you sure? Can you name UWP app that dnSpy works on?

[@llothar68]

Get some student kid on Fiverr a little bit of money to localize it. Program resources are hard to automatically translate because of the requirement to need the shortest possible translation and the little context in which the words appear. Manual translators need screenshots or you get the same ackward translation as using Bing translate.

Close and trash that project then follow along with the tutorial as normal (I am sure there is a way to install it with PowerShell but I don't use NuGet that often). The option should now be available as shown in the video. Note: Caliburn.Micro is no longer under active development at the time of writing this comment. The original creator, Rob Eisenberg, stepped away from the code years ago; it was being maintained by Nigel Sampson. In June of 2020 Nigel stepped away from the maintenance of this code as app development is no longer the primary focus of their new job. Nigel will still continue to host the webpage and has pushed the release candidate for v4.x, but is looking for interested, responsible developers to transition and continue the opensource project.

@@IAmTimCorey If is it a good idea to start brand new project in UWP after .NET 5 will be released.

[@IAmTimCorey]

I can't guarantee the future but Microsoft is putting a lot of faith in UWP as the future.

Would you consider making a video for the new Windows App WinUI3 ? I want to start a project specifically for the Microsoft Store. I haven't been able to find any enterprise-level content on database connection patterns for a few days. I don't know if I should connect the MVVM pattern directly to SQL Server. Or if I should develop a Web API and connect to the database with it. Maybe I need to create a Cosmos DB in Azure for licensing and set up a local SQL Server Express for the user. Where can I find content on architectural questions like these?

[@IAmTimCorey]

WinUI 3 is not very high on my list of things to cover, specifically because Microsoft doesn't put a lot of effort into it and because it is so limited in where it can be deployed. Even Microsoft recommends WinForms and WPF over WinUI 3. But as to your questions, building an API is almost always a good idea. It allows for more secure communication to the database and it allows you to have multiple UIs that work off of the same logic. This allows you to build a WinUI 3 project today and then easily transition to an Uno project tomorrow so that you can have your app deployed everywhere.

[@markcain2116]

I didn't have a Web API option in services.

[@IAmTimCorey]

My guess is that you need an update to either Visual Studio or Windows. Then the plug-in should update itself with the latest options.

I Think Windows 10 versions have an 18-month support period from release, meaning 1809 is the oldest still supported version. So, for non-business use cases, this is the most extreme (and still practical) min version to use. This is just my opinion.

[@IAmTimCorey]

It all depends on the audience. There are a lot of people out there with older laptops/desktops. Even people on Windows 10 don't always have the latest updates. What Microsoft supports doesn't really affect what people use.

Will there ever be a day when the barrier to entry into programming basic applications on Windows isn't such a horrific nightmare? It is sad when we have to rely on reverse engineering complex code that is generated from a code generator. Sometimes I wonder if some software developers are trying to over obfuscate things in order to restrict entry into this field.

[@IAmTimCorey]

No, I think the issue here is the plethora of options. If you had a really simple system, it wouldn't do what you want. So you would add a feature or two to make it perfect. Now imagine hundreds of thousands of people did that. Think of all of the options you would have. That's the issue. .NET Core applications have done a better job at hiding the complexity at startup. Look at how easy it is to get started with a Blazor Server app even though you are using dependency injection, application logging, HTTPS redirects and enforcement, SignalR, and more. UWP is just messy. Don't overlook what we are doing by reading the code, though. That is one of the best ways to learn how to build code, by reading code. Don't discount that as bad.

[@longbra]

Thanks for the reply. Yeah, I think I will stay away from UWP for now. I come from Windows Forms with MFC, but most of my experience is in developing C for embedded microcontrollers. Most of the code on the embedded devices I had worked on was written by me (no RTOS). I'm trying to come up to speed with WPF and .NET Core now that I'm out of a fulltime job and need to find a source of income soon. Also, thanks for all your your fabulous videos.

[@vandeljasonstrypper6734]

I don't know if I should trust this But the marketing is so risky + UWP just got removed it's ad-platform + UWP got performance issues with windows 10 + UWP have sandbox + UWP have so few supported libraries so rewriting everything from sratch is pain in the ass The only place the UWP is recommended is Kinosk mode For single Computer purpose in Enterprise But remember I don't mind the those limitations, but I really concerned the how Microsoft support it They put a bullet in Windows Phone, Windows RT and even Cortana I don't know whether I should recommend this to any kind developers and we seem don't have great choice either. Win32 is so OLD Right now the best way to treat .net is a cloud platform Stay away all the UI framework as far as possible P/s: the Windows IoT Core haven't updated since 2016 So IoT might be a no go

[@IAmTimCorey]

Yeah, I did a video on my thoughts about desktop apps in C# ( kzbin.info/www/bejne/r6KTlYahdpappq8 ). WPF and WinForms are actually pretty modern. They just got backed by .NET Core ( kzbin.info/www/bejne/q5SWpXZslNJ4rM0 ), they are now supported with MSIX deployers ( video coming next week), and you can put them in the Store. Working in the cloud is a great option, though, if you don't mind web. Razor Pages, Blazor, and even third-party frameworks like Avalonia and Platform Uno are great options.

[@dnwheeler]

Microsoft got rid of their own app ad platform, but you can certainly use another one in your UWP app. Not sure what performance issues you are talking about - UWP compiles to native code and is typically faster than standard .NET. The UWP sandbox is generally a very good thing, you can still write unsafe code and get "full system access" if you want, though. Any .Net library targeting the ".NET Standard" will work on UWP and the .NET Framework - most libraries are moving in this direction for maximum compatibility.

Hehe, this is the worst part about school. The assignment is to use UWP, not extensions... So this tutorial is essentially useless to me at this point :P

[@IAmTimCorey]

I wouldn't think so. While you might not be able to use the template code that the wizard builds for you, you can learn from it and use it as a sample for what you want to do. That way you don't need to manually figure out each step. You can see it done for you and then just bring over what you want.

Why has Windows turned into a mess like this? They keep abstracting over abstractions over other abstractions. This will not end up good in the long run. They need to develop new platform, agree on a set standard and virtualize all older apps. Windows has turned into a cluster-F. They have no direction or real innovation. It's a building pieced together with scraps. Who's leading the Windows development? They need to be fired ASAP.

[@IAmTimCorey]

Trying to maintain legacy applications while innovating is very difficult. I agree that I don't think they have done a great job, but it is a hard job to get right. Don't forget that a bit reason why UWP struggles so much is because people won't get off of Windows 8, 7, and even XP. Creating a new OS/system would be even worse. Virtualization isn't really the solution, either, since you would end up basically running multiple older operating systems in parallel with your main system, which would cause all kinds of security holes.

[@seephor]

@@IAmTimCorey I think Microsoft has done too good of a job supporting legacy apps but It's a double edge sword. You trade off having a better operating system with apps written for Windows 95 still able to run. I think Apple has a better balance on this thus a cleaner architecture. Look how they pulled off moving off Intel to ARM with virtually zero issue. I think it's possible for Microsoft to clean up by rewriting all their GDI windows APIs with what've learned so far. They can then support legacy apps with a Windows 10 sub system that's decoupled from the host OS via virtualization. They can then pour all their resources into a single development stack native to the OS API. Eventually after a decade, they can drop the legacy Windows support. Imagine all the new employment opportunities this will bring to the market. It's a bold move and I think it's possible from a technology standpoint. Whether Microsoft can pull it off is a different story. The failures of Microsoft beginning from Windows Vista to present has really been shameful.
