how track location using maps in ASP.NET Core razor page?

I want in my web app the customer can track live location and know where their order is when it with delivery, in ASP.NET Core Razor page

What you are asking for is how to create an extremely complex service, which is something that is impossible to give a simple answer to. In the case you already have created the complete backend of your live location tracking service, and you are just looking for the visual aspect of your solution: then you should search for a service/library which allows you to add GEO maps to your Blazor pages. The library you use for this should also have an option which allows you to add your own data, such as landmarks for the order locations. An example of a service I found online is Azure Maps. I also found a nuget package called Majorsoft.Blazor.Components.Maps which could be useful.

Get Html from Web page and create Setup project for Wpf Application (C#)

I'm trying to create a wpf application such as a movies library because i would like to manage and sort out my movies with a pretty interface.
I'd like to create a library with all my movies getting information from the web, but i don't know how very well.
I thought to get the information from a web site, for example imdb, but i don't know if it's legally to capture html from page to get the nested information.
It's my first desktop application and I would also like to know if it is necessary to create a database within the project and then create a setup project with specified script for deploy it.
Sorry for the confusion but i would like to know too much things :)
Thanks a lot in advance.

The legality of web scraping is a grey area. See my question, "Legality of Web Scraping vs Normal Use" and the corresponding answers for some insight.
Even if the legality is not a problem, web scraping is a flimsy approach because the webpage structure may change without notice, making your application suddenly useless until you update it to the new format. You are much better off using some sort of web API (if the site providing the information offers it).
Whether you need a database or not depends entirely on what your application will be doing and how you design it - it's not something any of us can tell you.
Same goes for the setup project - in fact I wouldn't worry about that until you actually have a working application. Take it step by step and keep the scope within control.

Yes I did not think about api.
It's a great idea, maybe use "themoviedb".
But if i create an application based on it, that has to show all the movies that you have stored on your hdd and get , for example, the posters, the description and the ranking, i have to create a database according to you?
Thanks a lot.

Which API to use when starting with Bing Maps

I've spent most of the Christmas reading through the Bing Maps information. However, there are so many different options and choices that I'm getting stuck on the plentifulness.
In one of the most obvious URLs I see both non-API and API approaches. That's confusing. There are AJAX, REST and Spacial Services and, to the best of my understanding, they do pretty much the same. That's confusing too... :)
So, here's the question. I'd like to create a web page that given a certain input (e.g. XML or JSON) will provide me with an image. The image is supposed to be a map with plotted pins (that contain my descriptions), controls for zoom/pan and (preferably) even traveling routes (automatically computed or provided by me) between those pins. Also, It'd be great if I could set a semi-transparent polygons covering some areas.
Which API am I supposed to use?!
I sis something like that a few years ago with Google Maps but as far I recall, I only sent in a XML file and the map was hosted more or less at Google's.

If you're building a web site, then you'll have to choose between the AJAX Control and the REST services. Basically, the AJAX Control allows you to embedded a map in your page, add pushpins, draw shapes, display routes...etc.
See http://www.bingmapsportal.com/ISDK/AjaxV7#CreateMap1 for a live demo.
The REST services are more useful for tasks simple like static imagery as well as requests like (reverse)geocoding and routing, that don't involve user interaction.
If you want a full "map control" that allows the user to interact with keyboard/mouse, use the AJAX API. If you're not, REST services could be enough.
EDIT:
AJAX API = AJAX control = AJAX v7
Spatial Data Services is a REST API that allows to compute spatial requests against a large number of data. It shouldn't be used to display a map.
If you're interested in something that allows your users to pan/zoom, create pushpins by clicking on the map...etc., then the AJAX control is the most suitable. It offers all the javascript stuff to display a dynamic map that allows user interaction.

If your XML file is in GeoRSS or GPX format then take a look at the modules for Bing Maps here which show you how to do this in a few lines of code: https://bingmapsv7modules.codeplex.com/
If your XML file is a custom format then take a look at the GeoRSS module to see how to read XML in JavaScript.
If you have more than a thousand items in your XML file I would highly recommend storing your data in the Bing Spatial Data Services which will expose it as a spatial REST service, or uploading it to a database and using a web service to load the data to the map. Loading more than 1,000 pushpins to a JavaScript map could be slow. Using a service you can load only the data that is in view which would make your app much faster.

jQuery.load() with sitefinity

I'm going to develop a website which uses ajax to load pages. The cms behind it, is going to be Sitefinity. The problem is I don't know if it's possible to load the pages of sitefinity with jQuery.Load() or any other ajax technique.
Problems with sitefinity:
- I'm able to get the page object of sitefinity, but i need the rendered HTML.
- I'm going to make the pages in the CMS and each page will have a html, header, body tag etc. And I just need the main content of the page, so i'll have to strip the html aswell!
I've been searching alot, but haven't encountered a solution. If someone could give me tips where to search, or how to do it, I'll appreciate it alot!

A more efficient way to pull the pages in would be to connect to the Sitefinity WCF service with jQuery. You will receive JSON page data via AJAX that you can use to compose your page.
Your project's /Sitefinity/services/ folder is filled with .svc service files that you can query to get various items such as pages (/Sitefinity/services/pages/PagesService.svc/), images, blog posts, etc.
The documentation for using those services from jQuery is a little sparse at this point, but they are actively being improved.
See: Sitefinity Documentation Calling Sitefinity RESTful WCF services from Client Side
And this is a good example (non specific to Sitefinity) on how to call WCF services from jQuery.
One note: Sitefinity is very modular and serves pages and content items separately, you may need to query for a page first to find out what content items need to be queried.

Ask on the SiteFinity support forums. The devs are pretty good about answering questions on there.

Yes, it's possible to retrieve content from Sitefinity via .load(). You can use only a portion of the returned document by doing something like the example below.
$('#empty-container').load('sitefinity-page #main-content');

Creating a widget

Hi i want to create a widget which can be embedded on other websites similar to the twitter profile widget, an example is here;
http://twitter.com/about/resources/widgets/widget_profile
The way i would approach this is to return the data in json format via my wcf, the problem is looking at the twitter example there seems to be some javascript and i am not to clued up on the purpose. My question to the more experienced devlopers is am i on the right track and what else will i need to do. Thanks alot

The purpose of the javascript would be to actually call your wcf service to retrieve data and write the html results to the screen. In the twitter example, many options are set inside a javascript object that is used to manage the configuration (background color, username, etc). You can return json, and then take the values from json and plug them into an html template on the client side. If you want this to be used on other sites however, I would probably avoid the use of jquery as you can't be sure the user has included it, and so you would need to include it. And then you have versioning issues if you use an older version, and the website your widget is on wants to use a newer version.

There is an interesting blog post that explains how to create a widget, loading jquery and css safely, making JSONP calls and more:
