I want to use SignalR in my project for real time chart updates.
My project is developed in WebForms with VB.Net Language.
I searched for for 3,4 days but all I found were MVC examples. Can anyone suggest a solution?
Please notice me. Thank you
You can use SignalR with webforms, see this question for example :
Can SignalR be used with asp.net WebForms?
However, it will require to make your current webforms project evolve in several ways, which can be a loss of time and a risk if it's an old project hard to maintain.
An alternative could be to create a completely new web project for the backend with everything required for a clean support of SignalR server, and to consume it in JS (using jquery.signalr, etc) from your currently existing webforms pages on client side.
The ability to achieve this kind of thing will depend of what version of .Net and SignalR you could/must support.

Hello I have built an application using asp.net MVC, this project is all working well but I am finding a lot of documentation with Stripe has documentation depreciated, however, the documentation is fine for asp.net core
Is it a massive change between the two types, why doesn't it seem to work with my one. I am new to all of this but it doesn't really make a lot of sense to me so please explain in lamens terms and link some articles if it would help :)
I understand your confusion :D I've worked with ASP.NET for very long (since web forms). I'll try to explain to the best of my understanding.
MVC is a design pattern that has seen a lot of success and has been adapted widely by several frameworks. ASP.NET MVC is the dot net implementation of the MCV pattern.
ASP.NET Core is a redesign of ASP.NET with a lot of new features and benefits. The biggest advertised differences is the fact that DOT NET CORE is open source and cross platform.
In an asp.net core web application you will still see the MVC pattern with several improvements since ASP.NET MVC.
If your project works perfectly you don't have to do a complete redesign. The frameworks will keep updating and as developers we need to stay updated but we can't go and redesign every project. New projects are a different story. If you start something new definitely consider using ASP.NET Core.
Here is one of Microsoft's docs that helps understand the difference.
https://learn.microsoft.com/en-us/aspnet/core/fundamentals/choose-aspnet-framework?view=aspnetcore-3.1
If you split your application into different projects for the front-end stuff, business logic, and data access, it shouldn't be too painful to port it over. The business and data access code should mostly work the same way. it's just the bit of MVC presentation stuff that will be markedly different.
I am trying to migrate a project from classic ASP.Net Web Forms to ASP.NET MVC.
While I have read through http://www.codeproject.com/Articles/38778/ASP-NET-WebForms-and-ASP-NET-MVC-in-Harmony. I have a basic idea on how the code structure, libraries and routing should be done.
For your information, the scope of my existing project is around 400 pages and 300 tables.
On top of my head I have two approaches:
Start from stretch, rewriting the whole system - Obviously this would require intensive work and take a long time. Any change made on existing system would need a duplicate change made to the new system.
Migrate the page one each - I still have a rebuild the entire core library (for accessing db), and get the page migrated one by one. For this I would assume to have two core libraries (new and old) running simultaneously with different pages connect to one of those.
Would anyone have similar experience and advise a proper way to start?
For this complete revamp I may also target at the latest technology - .NET Core and MVC6, by taking these would I have extra advantage, or some blockages I would have to take care of?
Any suggestion and opinions are appreciated. Cheers.
Microsoft is a bit hush hush on the subject but the WebForms engine is probably never going to make its way to ASP.NET Core. One might think that MS is waiting to see if the community is calling for a port, but I think they're trying to kill it discretely (not like Silverlight).
Why? Because it proved to be a bad good idea on the long run, easy to use at first, but extremely complex to master (because of viewstate and page lifecycle), with a tendency to allow average developers to build very tedious application (in french we say steam factories). Also it was very poorly adapted to modern web development (Ajax, unit testing, IoC). They tried to fix it with a couple of tweaks, but the overall architecture is just not adapted to this kind of things. MVC is a treat in comparison!
To answer your question, it's not really possible to migrate WebForms to MVC, because those are quite different architectures, and of course the architecture is what an application sits on top on, so if you change it, you might as well rewrite it from scratch.
What can help you a lot is if your app is divided in tiers (business, data access, UI). If it's not the case, you could start by doing this, properly separating the UI project from the rest. Then you would just have to rewrite the ASP.NET project and not the rest.
There are some useful resources I'd like to share with the StackOverflow community just in case you are having troubles to decide what to do:
modernization of your existing Web Forms app
migration to MVC or Core
or whether to start a new project on Web Forms, MVC and Core.

DotVVM package helps us to migrate ASP.Net Web Forms migration to ASP.NET Core without re-writting completely.
i have not tried any production application. still have tried some sample pages. you can try this out.
I can agree that for many cases a re-write of an ASP.NET application where WebForms is used widely may do not provide any business value.
Therefore we decided to use our experience with ASP NET WebForms to develop a highly compatible port of WebForms for ASP NET Core / .NET 6.0.
We use the solution in our own ASP NET WebForms-based products and projects as well as a licensable component library.
So the Forms can still be used and you can focus on the .NET CORE/6 migration.
I have been doing windows applications using c#.
But recently our management has planned to make some of the projects to be web based.
We thought of using asp.net with c#.
Can anybody guide me on effectively learning asp.net.
pls provide some useful links for sample projects.
Thanks in advance.
Web Forms would be a quicker route if your used to desktop development (over microsoft MVC). MVC3 is my preference but takes a bit longer to get used to if your not familiar with it. MVC3 gives you more control over your code and in my oppinion is less bloated.
May be worth looking into the MVC pattern if you go down this route.
Loads of videos to get you started here: http://www.asp.net/web-forms
They have a couple of example applications you can work through:
Web Forms: Contoso University App
MVC: MVC3 Starter App
as simple as this: http://www.asp.net
I'd recommend to start with ASP.Net MVC even you'll find it a bit complex in the beginning , Here you can find a lot of tutorials and books
you can also take a look at the MVC Music Store , it is a complete project to learn ASP.Net MVC by example.
I would steer clear of WebForms - even though it may seem a more natural fit coming from your WinForms background, you will run into issues later on. Given that you're going to have to learn a new platform anyway, makes sense to learn MVC and get off on the right foot (note that there are alternative MVC frameworks to ASP.NET MVC such as Fubu but these are probably riskier options in your situation).
PluralSight do some good online training courses, though you do need to pay for them.
I am starting a new project in VB /.Net Framework 2.0 for a company corporate website with data driven forms. So should I go further with Asp.net MVC or Asp.Net web forms and WHY ??? We are not ready for Ajax now but later.
And also we have DevExpress components.
Actually I see ASP.NET MVC as next generation in that it is an evolution - trying to be a better programming environment, as software development for web apps asks for something more testable.
It is a huge beast. Decide based on features whether you need it. MVC has less documentation and is a lot harder to master thanks to a less RAD approach, but it seems that once you are in, it will be quite a better experience. If you have a web application (like stackoverflow.com) then it may be a good approach.
DevExpress components - have fun... throwing them away. Like most ASP.NET components they will not work or only work very partially. Totally different approach.e
ASP.Net MVC is not "next generation" ASP.Net. It's an alternative approach to design that can be more beneficial depending on the kind of project you're working with. Without more information about the particular type of project you're working on no one can give you any informed recommendations.
I'm trying to upgrade my existing web forms application to upcoming framework and rewriting couple of workflow as per the new business requirements. I want to introduce TDD based development in this project but after some investigation found that ASP.NET MVC will not help me as my web existing application is using lots of Infragistics UltraWebGrid controls for grouping, paging, column moving etc and there is no good alternative grids in ASP.NET MVC world. I also need to support blackberry in this release. So, am planning to use both MVP for desktop client and MVC for blackberry client in same project.
I would like to know if someone has done something similar in their project and links to any good open source asp.net applicaton using MVP pattern. I dont want to use WCSF as it is too heavy weight. I saw their MVPBundle sample application but it lacks use of modern tools like IoC (Unity or StructureMap), Mocking framework etc.

The latest incarnation of Nerd Dinner has mobile support in an ASP.NET MVC app.
I'm not sure about the JS support on a black-berry but there are quite a few grid/repeater type controls and mechanisms available using either jQuery or the forthcoming ASP.NET AJAX 4 templating controls.
