If it's possible, how would I control things like redirect users to a certain page upon successful login or better yet prevent users from accessing any page other than the login page if they're not logged in?
Remember that I did not mention MVC or Web Form. If it is possible to secure my project without using MVC controllers or web form, how would I authorize users after successful logins?
I guess my question is not very clear. What I meant is can a web project folder and web files (.cshtml, web.config, etc.) be generated using functions we write in a Web API after the Web API project has been built and deployed to the server.
Basically the question is, can we send a call to the Web API functions at run time to create a web project folder and web files dynamically (meaning this happens after building and deploying our Web API project to the server).
Does anyone know how to produce an excel pie graph in excel through MVC C+, Jquery or even SQL? I have the pie graph with rows 1 to 10 and would like to produce a pie excel graph with data in it when the excel is downloaded through a website.Any links would be appreciated, many thanks and remember to sneeze into your elbow!!
As far as I know the graph details need to be embedded in the Excel worksheet. I guess it may be possible if you know the worksheet layout to add the details through the use of the ACE Excel driver. But I am not 100% sure that that is what you are asking.
Not quite, but I guess close. Someone is going to be drawing a report from a website. Inside the excel spreadsheet is various data. I want this data (when opened in excel) to also have a pie graph attributed to it. Thanks!
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
The same would apply to automating it from SQL.
Sounds like you need to investigate each issue one at a time and test it.
Like how to write the JWT token to local storage, or the view bag or something.
Then how to get the controller to expect the JWT token [Authorize]
And how to send the token to the controller in the HTTP header. Do some reverse engineering.
I looked around on the interwebs and just basically saw nothing of value.
Just a bunch of forum post saying look at this by people who have never worked with JWT.
most talk were for core.
Sounds like a big job to me just to investigate it.

you are right and that is why I posted here to see if someone has done it.
I have a legacy system that is written in dot net 4 and MVC4
were currently trying to strangle it as it is used by the whole company. With the new stuff we are using JWT and have a single sign on API which works and works well. BUT the MD wants to me see if it is possible
Every day, thousands of innocent plants are killed by vegetarians.
I think it's possible to do personally, although I haven't done it nor put any day long research into it. Or perhaps at least just start with a piece of JWT, such as picking up the token from the other modern project to background validate in the old MVC4 system so you don't have to sign in again, and then the old system just runs as normal. That is very plausible to do. It's even plausible to me at least, to modify the old system so when you sign in, it writes a JWT token to local storage as well so you don't don't have to sign in to the new system.
I pretty sure I can write a hack of AttributeUsageAttribute and call it [Authorize] that I can decorate the controller ActionResult with that will validate a token. Basically a hack of System.Identity but in a smaller package. Store the token in a cookie and can read and write it.
On SPA apps, well Angular at least, you don't have to store the token in Local Storage, but it can be stored in a cookie as well. But the cookie has to be a real single value cookie, and not the asp.net cookie that can store an array of values.

I'm implementing asp.net core project. I published my project into a package and set it on a main server, but, the database was set on another server. To do that, in the part of connection string of appsetting file, I just changed the server name and database name and when running the project I confront with the following error:
An error occurred while processing your request.
Request ID: |6baffbe3-48f1cf1e3a28ac47.
Swapping to Development environment will display more detailed information about the error that occurred.
The Development environment shouldn't be enabled for deployed applications. It can result in displaying sensitive information from exceptions to end users. For local debugging, enable the Development environment by setting the ASPNETCORE_ENVIRONMENT environment variable to Development and restarting the app
I appreciate if anyone can suggest me a solution for it.
You are assuming a database connection error, the production system has hit an error but will not tell you about it because of security concerns - it could be any error, not necessarily the DB connection. You need to get more information about the error either from the logs or turn on development mode.

Part of learning .Net Core requires you to take a deep dive into how to setup the environment using the Program.cs and Startup.cs, and how to use environment variables. For my database setup, I ran a database on my workstation to develop on, and one on the production server, and used the appSettings file to switch between production and development. If you can contact the database server from your workstation, then all is good.
So using the development mode to run off the production database server would be a good way to figure out what's happening. Then maybe take a step back and setup your environment.
I need to display one image that is made up of multiple images with each a transparency.
So image one has a bike on the left and the rest of the image is transparent and the second image has a car on the right (again the rest is transparent), then I would need to display one image with a bike on the left and a car on the right.
How can I accomplish this in MVC Core 3.1?
As the user can select the images that build the total image I cannot prebuild this image.
