One of the biggest enhancements is support for Windows desktop applications (Windows only). By using the .NET Core 3.0 SDK component Windows Desktop, you can port your Windows Forms and Windows Presentation Foundation (WPF) applications.
It is an ASP.NeT core razor pages solution. I have three projects in my solution "OdeToFood"
1. OdeToFood (Original Project)
2. OdeToFood.Data (.Net Core Class Library)
3. OdeToFood.Core (.Net Core Class Library)
In OdeToFood.Core, when I use the following using directive in a class in OdeToFood.Core:
it works perfect.
Similarly, when I use the following in a class file in OdeToFood.Data
it works perfect.
But if I go to the startup.cs file in the "OdeToFood" Project and use
It gives an error: The Type or namespace 'Core' does not exist in the namespace "OdeToFood." (Are you missing an assembly reference?)
I know html, css some fundamentals of js and C#, and I have decided to delve into the world of asp.net. I have learnt that there are two options to begin with, razor pages and mvc. But Razor pages seem to have very little future at present.
Which is better, Razor pages or MVC to begin with? I am only 19 and I want to devote my life to coding
I am very new to ASP.net and C#, so I am trying my best, but there are stille many things that confuse me, especially because when I am looking at various examples online they give me different answers to the same solution, which just makes it even more confusing.
I made a person class, with two subclasses (driver and admin), but I can not get the ArrayList to show up when I run my Index file. I only get a parse error.
Here I get the error: "An object reference is required for the non-static field, method, or property."
If I remember correctly, a solution to this would be to make a static ArrayList, but I am not sure how I can do it for this code.
Hi again and thanks once again.
I did do ask you said. The reason why I tried playing around with the ListBox line is because I am getting an CS0103 error: "The name ListBoxResults does not exist in the current context", which I don't get, because I looked in my index file.
I have migrated asp.net 2.0 VS 2005 application to VS 2015 (framework 4.5).
Site loading fine. But when i click on the menus available in the page, actually it is not adding localhost in the redirection url.
My Home Page : http://localhost:1087/CGP/Home/Home.aspx. This page is loading fine.
In this page I have side menus and each menu "Profile" will have hyperlink like : CGP/Emp/Profile.aspx
But when I click on the menu "Profile" it is redirecting to http://CGP/Home/Home.aspx.
The term localhost is missing. I am not sure how to handle this.
I've been developing in ASP.Net for over 12 years and, though it was a bit of a learning curve to start, feel the webforms environment is, for most purposes, pretty good. When MVC came on the scene (first via 3rd parties such as Castle's, then through MS's own offering) everyone pretty much jumped ship declaring it the best thing since sliced bread. As I had a commitment to supporting a number of webforms applications, I didn't initially have any need to switch; and subsequently haven't found any compelling reason to do so. I've looked (briefly, admittedly) at MVC but felt it was a steep learning curve and didn't seem to offer any advantages, and have some actual disadvantages, to what I was used to.
I answered a question in Q+A today where I mentioned Webforms, and the need to decide whether to go webforms or MVC, and a subsequent comment was "I will not recommend webforms".
So I'm curious: what is it about MVC that makes it so much better than webforms? Is it simply that it's flavour of the month and commercial requirements for webforms developers has crashed? (plug: I have a requirement for a webforms maintenance developer ... message me for more details)
Is it that MVC is a lot "better", or do people feel webforms is actively "bad"?
My applications, using webforms, successfully separate business functionality from presentation issues (and indeed database/storage access from business objects). They implement multi-level inheritance, use custom controls to implement standard functionality, incorporate AJAX-based interactive features (not using Microsoft AJAX controls); and have proven to be flexible and extensible. Not yet found anything I can't do with Webforms.
Guess I must be the biggest opponent of WebForms here, even as far as calling it stupid.
What I didn't like?
Didn't like the way they tried to make it like WinForms, in which objects create HTML. So you create all these labels which are just span tags. Then when you go to port your HTML to another framework, you have to change all the objects back to actual HTML. As a negative effect, you never really master HTML or HTML5. If you stick with WebForms and not move forward, you stay stuck in that world of objects for years, never really moving forward to support phones, tablets and desktops.
I also got burned by the Ajax Control Toolkit. It worked great locally, but failed on long distance connections. The Partial Update control worked the same way. They added so much junk that was never really stable. Perhaps a WebForms app written for in-house use might be OK, but not for world wide production use. And then all of this stuff has to play nice with the Web Server such as IIS. It seems like WebForms with it's ViewState worked tightly with IIS server in order to post data back, and IIS server would have to keep track of every session out there.
Google just didn't play nice with WebForms. WebForms had a way of placing a script on the page, and using a weird URL for it's location that Google didn't like. I think it was a query-string added to the script name. Then Google complained about other elements I had no control over. And then the single use of the Form element, and having to work within that parameter or rule.
I could name probably 10 more things I didn't like about it.
I dumped WebForms and went MVC, and loved it. After the steep learning curve, I was able to reduce the time for new projects in half. Learned how to write very effective models and are close to my database designs. With views and razor, I was able to create new UI that where more user friendly, and much more fluid. Learned Gulp to package my CSS and compress files.
Then I dumped MVC and went .Net Core MVC loving it even more. Delivering blazing fast speeds but I still didn't care for Razor much. But my SEO tests were off the charts and Google loved it.
Last, I took the Angular jump, Angular wrapped in a .Net Core project. Figured out how to pack all my stuff like SASS, and compile it into a single project that runs in a Docker container. With this technology, I can now focus on providing a great user experience, with super efficient models and database designs, with blazing fast speeds. I spend very time writing code, in which most are just a few lines. I don't have to worry about slow connections any more.
Now I can develop in 1/16 the amount of time it took me in WinForms. My website below is version 298 at the moment. I have no regrets at all about leaving WebForms, even MVC as well. The WebPack train is running and lots of people are hopping on the train.
If it ain't broke don't fix it
