[@Aphradity]

I am so glad to hear you will be covering application signing and developer certificates, this has been a major source of confusion for a while. Is this the same certificate you would use for passing SSL / TLS certificates for secure communication connections? Also, do you plan on doing a video to discuss how to create the type of certificates needed for secure communication, and how to have applications accept your certificate?

[@brianhoskins1979]

I like the d: binding. I used to use the fallback value for that because the designer would display it, but that can have consequences at runtime as well if you forget to initialise in your model. So this is better.

Thanks Tim, great info.... I like ClickOnce.... It's super cool as it comes back in .Net5 again.

Thanks again!

This is great, thanks Tim, so practical. I hope they add the deployment webpage feature, all please go up vote it! If you create another video on this (and please do) it would be great if you could explain more about the signing of the app. Where is the best place to get the certificate from? What option (product) to choose from on the site? Can I sign more than one app with the same certificate? After a year I buy a new one and then replace the old one? Some questions about ClickOnce: Can I set my publish location to an Azure container? Is there an advantage to using Azure App Service over a public Azure container in this use case? Why does it give me (and you) an error when pasting the URL? Is that a bug? With Target runtime, is Portable just the way to go? When to use the other options? What is the lowest version of Windows that a .Net 5 WPF app will run on? If you only get to most of these questions in your next video, that's fine, I'll wait. :) Ps. Setting the minimum version to the same as the current version is a great way of not giving the end user the option of skipping the update, solved a lot of problems for me.

Thanks for the video. Tim , how to handle appsettings.json in this scenario? Let's assume there is one. User has updated the file manually and with the next update you want to add new setting to the file. ( something I've asked about before , but the videos for TimCo don't answer that ). Do we have to code something into the program to 'create' new settings but never overwrite the file ? Or perhaps create a different json file ? But this could lead to 100s of json files in big project. Thanks

Thank you for this demo! One comment. If you use .Net Core or .Net5.0 you will need to publish function anyway to collect all files as input for the installer. When I just migrated to .Net Core, my installed projects did not work very well, till I discovered the Publish function.

They have improved it and made it more stable. It is also now in Xamarin (again, a new version that works better).

[@Isra-p1]

Hi Tim, thanks for this wonderful video. So, as a .NET noob I wonder, what use cases would not be suited for click once and would better suited for an msi installer? Do you also have resources to learn how to deploy using msi installer?

[@IAmTimCorey]

An MSI installer would be necessary if you wanted to install to a specific path or if you wanted to add additional resources (install a database engine, update the registry, etc.)

[@luckyJYK]

Thanks Tim for the recent rapid videos on .NET 5. About the ClickOnce, is appsetting.json file available with this deployment ? Because if I'm not mistaken, it's not available with deployment into single EXE file.

[@IAmTimCorey]

You would need to include that file with your project and exclude it from the single file (if you are doing single-file - ClickOnce does not create a single file unless you tell it to). We do this in the TimCo Retail Manager series.

Does an application update download the full installation or is it also possible to do partial updates via click-once? In case of bigger applications it saves time and bandwidth.

Use Squirrel for Windows, gives your partial updates and you can embed your update UI inside your app.

[@RalfsBalodis]

What a great time to enter C#. So much cool stuff with C# 9 and .Net5... I had no idea that hot reload is a relatively new feature. For me - it was there forever. (That is 2020 start of summer) You have a designer pane next to your xaml but still, I found that it's just not the same when you can use hot reload. I just can't explain why that is... Also, ClickOnce. Looks very handy. Design time binding, kind of nice. But then - what the x: stands for? I use simply "Name" not "x:Name" if I have to reference element in my code. Seems to work just fine. not to mention xmlns:x... xmlns:d... xmlns:mc... What is a that?

[@tchpowdog]

Is your clickoncedemo app service a .Net 5 container? Because I just published an app service and .NET 5 nor .Net Core 5.0 was an option. I had to select 3.1.. I think.

At 29:10, I show off switching to .NET 5 before I created the ClickOnce app so yes, it is .NET 5.

I gather from the way you skipped over it, that Winforms "just works" as you'd expect? I've personally got no interest in WPF etc (I'm still sulking and ignoring new UI platforms after Silverlight ;))

[@BittermanAndy]

Last I heard, the Winforms form designer still has some significant bugs. Though at least it actually exists now I guess. Can't believe they put the designer so low on the priority list every time. I mean just look at the WPF experience that immediately follows in the video. "I want my form to look like THIS, so I type in THIS and THIS and need to remember to type in THIS..." Why would anyone want that in any kind of visual UI designer? It's like making an image with command line switches instead of Photoshop. Terrible experience.

@IAmTimCorey, Just a quick question, I work for a company that is transitioning from using a 4gl language (Genero/Informix) to dotnet. I have been working in C# personally for years but never bothered learning windows forms or WPF. I do have Win32 programming experience, but that's been 10+ years. My question is; should I spend my time learning WPF, or should I focus on a different UI technology?

[@Kirides]

Tl;Dr: use HttpClient. If you got that working, fine. If you plan on doing serious stuff: read up on "HttpClientFactory". in JavaScript you have XMLHttpRequest, fetch and then some other libraries that abstract things away even more. in C# you have "WebClient" which should not be used in any modern HTTP development and HttpClient which as the name implies, is a client for any sorts of HTTP-Requests and the only class that should be used for HTTP requests in C#. While you _can_ use the "HttpWebRequest" class to build and execute HTTP requests, it does not allow you to "plug-in" functionality like, eg. Polly, or any kind of Http-DelegateHandller as with the HttpClient.

Everyone now moving from MVVM to MVU Android: Jetpack compose Swift: Already there Windows: the reason why Microsoft had been invest so much in React Native to make UWP is because they realize how outdated MVVM is and they started making our own RxNet which is MAUI and it's not even close stable. .NET now are all about making dotnet core and the cloud .NET desktop developer now is completely 3 years fall behind compare to web technologies, leave Win32 and move on

Well, this is a bad take. Here's why - you assume that all development is only for the latest trend. The investment in WinForm/WPF has nothing to do with cross-platform development or running on ARM. It has everything to do with supporting the tens of thousands of applications and application developers who are building, maintaining, and improving desktop applications on Windows. As for MAUI being not close to stable, that's because it doesn't exist yet. That comes with .NET 6. Some of the work in .NET 5 was about laying the groundwork. MAUI is not some type of extension of UWP. It is the next evolution of .NET itself with the unification of Xamarin and .NET Core. This also has nothing to do with MVVM, which is a pattern, not a technology. In fact, Blazor Server implements a type of MVVM. The different types of patterns (MVVM, MVC, MVU, etc.) have their uses and values. They are not technology-specific.

design time binding like this to enter design data is f. stupid ... hate that they add stuff like this that will bloat the code ex. xml doc just show how clueless MS coders are they dont even know that you can bind designviewmodel at the root of the binding tree and load this one at design time

Dear Corey you make me a littlebit crazy with the summary and the strange arguments you give just show what to do and say this is the procedure, dont explain every stupid choice microsoft did made, because it is all preliminary, I am not so keen on your youtubes, but there is nobody else to display / demo the latest stuff. But i need to stop watching your youtubes, it drives me crazy and mad/angry man, i think i am impatient or something? did you have people with the similair reaction as i have. All dotnet .conf stuff from all microsoft presentors i realy can digg , but you not. Sorry.

[@IAmTimCorey]

No one is forcing you to watch. My content is different because I have a different focus. Instead of just telling you about new stuff, my goal is to prepare you for the real world. Knowing what something can do is cool, but knowing when to use it, when not to use it, what the best practices are, and what pitfalls to avoid enable you to make better choices about if you are going to use a feature in your specific situation. You see, just because you have the option to use something does not mean you should. I teach you how to make that choice.

Try and stop double and triple explaining everything and stop emphasizing so much on 'do you see this button, this button right here, these pixels I'm hovering over right this moment ...' just explain once and move on. Stop thinking that your audience is mentally incapacitated when first of all you post technical stuff. Overall this video shouldn't have been more than 10 minutes.

[@IAmTimCorey]

Doing this would be limiting my audience to a small sub-section of people. Instead of sharing "just the facts" and keeping it to 10 minutes, I make sure I am clear in what I am saying, I emphasize important points, and I explain context. By doing so, I ensure that a larger group of people understand the topic and know how to use it in production. If you wanted a quicker version of this video, go to Channel 9 and watch the video from .NET Conf on it. I took that content, plus some blog content, plus some research on my own and contextualized it into a cohesive whole.

@@IAmTimCorey I can see your point and understand that this is the direction you want to go and won't argue any further. At the end of the day it is your time and effort spent for us and for free, for that I am grateful be it long or short video. Stay healthy, stay strong!
