Excellent stuff! Just bought the whole course on udemy. The quality level is maintained throughout the rest of the course. BTW. I really liked the way you showed the other partial classes. It was confusing to me (I'm a java dev) where do all those variables come from. Plus you showed the generated class. That's the way to go:D Thanks again!
I have to say this. I have seen a lot of videos from Brad from traversy media, probably the best teacher on youtube but his videos feel like they are meant for someone who is into coding, not for someone who is planning to get started. Mosh's videos are great for newbies who are still not sure if they should pick the language or not. Great video.
I've paid 400 bucks for a course at university that is a part of my program for learning C language and feel like I've got scammed by my own school when I realize that Mesh offer better course structure and explanation for only 14.5 bucks (the c# course). Mesh, keep doing this your the best.
I so appreciate the atomic level explanations. So many tutorials jump to using multiple libraries to "help" make it easier to develop, instead they made it more confusing.
your explanation is great sir! but tell me 1 reason why should i buy ur course when there is free documentation on it and is publicly available to everyone ?
Mosh is the best teacher i ever had ! any subject in programming i want to learn first i check if Mosh has a course on that subject. I owe mosh my job !
Great video! Just wanted to say that, since the time this video has been uploaded, Visual Studio for Mac has been released. So, if you use a Mac for iOS dev, when you go to the link mentioned in the video you can download the latest Community Edition (2017 currently) and develop directly in Visual Studio for the Mac. Kudos to Microsoft for making this available. Although, there is now one less reason to use Windows ;). Would be great to also have the full IDE working on Linux.
Hello Mosh, great tutorial. I have a problem though. My android app in the emulator keeps crashing. I don't have a app.xaml.cs somehow. I have the following: app.cs: using System; using System.Collections.Generic; using System.Linq; using System.Text;using Xamarin.Forms;namespace HelloWorld { public class App : Application { public App() { MainPage = new GreetPage(); } protected override void OnStart() { // Handle when your app starts } protected override void OnSleep() { // Handle when your app sleeps } protected override void OnResume() { // Handle when your app resumes } } } GreetPage.xaml.cs: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;using Xamarin.Forms;namespace HelloWorld { public partial class GreetPage : ContentPage { public GreetPage() { InitializeComponent(); } void Handle_Clicked(object sender, System.EventArgs e) { //throw new NotImplementedException(); //DisplayAlert(); DisplayAlert("Title", "Hello World", "OK"); } } } GreetPage.xml:
Hey man, I like the videos. What are the options for visual studio 2017? Under cross platform these options are not the same. The options are Class Library or Cross Platform App. You think it best to chose the latter?
12:30 When I start up my android emulator I don't get the "Welcome to Xamarin" Screen. It's just the home screen that has fully loaded up. Do I have to wait longer?
Check the very bottom toolbar of Visual Studio as it'll update you as to what processes are occurring during emulation and how far the loading is. It's possible it can't load some of the elements of your build and if so it'll tell you either there or in the 'Output' window which is also at the bottom of the Visual Studio interface by default.
Thank you so much for your video. You do a fantastic job of explaining all of the pieces and how they connect with each other. In a couple hours following along with this video I learned everything my University Instructor couldn't explain in an understandable way. I was beginning to think I wasn't smart enough to write code in cross platform situations like xamarin!
Wish I could triple like this. I’m a seasoned C# developer but literally just finally getting around to trying to develop actual mobile apps instead of just web based front ends and Mosh so cleanly explains Xamarin without going into too much of the C# syntax that many of us already know well or spending too much time on how Xamarin talks to the respective APIs for Android or iOS which is really not necessary for us to intimately know. Focusing on XAML in just really the easiest to follow along tutorial I’m so happy I came across this channel. I’m a new fan and a humble one because I didn’t have a lot of time to figure out how Xamarin works and this saved me a ton of time.
@@programmingwithmosh Well, back in 1960s they drew images as well. A programming interface need not be code. And had crazy ideas, like async runtimes, non-file-based code bases, etc.
Xaml is the worst way to design stuff, in my experience it is hideous and extremely buggy and it is apparently not effective to design visual stuff with text , just seems like it would be 10x better if it was in any other way.
I started taking a Mobile App Dev class, instructor is teaching Ionic which I didn't like. Since he allows us students to use whatever framework we want, I chose Xamarin since I'm proficient with C#. This tutorial was awesome! I wish I had the money to buy the whole course. I think I'll save money for it. I liked your style a lot. Keep up the good work!
When you use a software let's say Xamarin and you get some errors from the start and everyone says that the way to fix these errors is by reinstalling the software, well that's when you realize that you're smart enough never to use this shite again...
Which NuGet packages is being used in this video? I see 7 available for update, but I only have 3 installed. NETStandard.Library Xamarin.Essentials Xamarin.Forms + the 3 I see in the video Microsoft.NETCore.UnerversalWindowsPlatform Xamarin.Android.Support.Design Xamarin.Android.Support.v4 So I'm kinda missing out on one. Can anyone help me here? EDIT: Nevermind, saw the Xamarin.Android.Support.v7.AppCompat afterwards. :-)
Gonna watch this tutorial, but I have a question: is the file size for apps created with this big? How large file size does the app you create in this tutorial have?
you are such amazing where you got all that from , i am just thinking how you manage to learn deeply all these programing languages, soon i will be join one or two courses i like the way you are teaching and understanding of what you are promoting , thanks with love.

You're awesome, structured and with clean explanations, good work! You gained a new subscriber ;)
at 1:00:00, the if(Device.OS == TargetPlatform.iOS) and all that...I am getting a message that this is now obsolete and to use 'switch (Device.RuntimePlatform)' instead. But that doesn't seem to be working for me in the way I have it formatted apparently. Any quick suggestions on syntax change?
thanks mosh ..i've been trynna configure the new project window but the items listed aren't similar to what was on my screen... i'm using the recent version of VS .
dear sir plz give us all video free plz plz plz because we're not capable to purchase your course and today you become our god, sir plz plz plz help us make it free sir plz we loves you sir

This guy is good but not generous enough to share some free complete courses with us. All those videos are the beginning of some series. The message is clear - if you want to watch more? $$$ or no.
Most of apps that crossplatform doesn't need details for control cameras, toast messaes ... so if you are going to make simple crossplatform app, then using Xamarin.LABS isn't bad choice
Hi Mosh. The bookmarks are great Is that what they are called? Can I bookmark parts of the video I want to go back to for myself? How do I get the pdfs you refer to please? I am using VS2019, and I get a lot more options with Xamarin and XAML now.
I am using Visual studio 2017 on windows 10, I am facing trouble to create the cross platform project. If I go for "class library(Xamarin.Forms)". it gives me portable class library only. If i go for Cross platform for app(Xamarin) , it gives me "project templates building for cross-platform for iOS, Android and windows with xamarin" What should I do? I am getting error for updating package - "Severity Code Description Project File Line Suppression State Error Unable to resolve dependencies. 'Xamarin.Android.Support.Design 25.4.0.2' is not compatible with 'Xamarin.Forms 2.4.0.282 constraint: Xamarin.Android.Support.Design (= 23.3.0)'.0" what is that mean?? Check above video for on 9:21 that's my error
out of date and I am running vs 2017. Nothing I have matches anything in this tutorial! I can't even get past the setup instructions starting 8 minutes into this tutorial!
A few things have changed. Now there is only one option in Cross-Platform. And when you start the project, There is a Solution with only 4 projects: The app name, the app name.Android, The app name.iOS and the app name.UWP (Universal Windows).
For those of you who live in year 2018, DO NOT update your Xamarin.Forms and Android.Support packages - especially if you don't have the latest Android version, phone or emulator. It's alright to use the current version, because it's optimum for your currently existing Android API. I just got through this error and saved myself with it after a long enough time.
Hello Mosh Im Brazilian, and i bougth your courses for a long. I Want to thank You for your Work and say tha you have being changing my live! For Real. Aftar i Start to watch you i created i app and this helped me alot! Bot I back to Visual Studio And after some atualizations a lot of things are difrent so, coud you comment some updates off xamarin forms? Some in the PCL Template ... It's just a sugestion. A Thank You Body from Brasil !
