Wondering why my system is giving me the message: "Error NETSDK1045 The current .NET SDK does not support targeting .NET Core 2.2 ... use a version of the .NET SDK that supports .NET Core 2.2"
I put line numbers below for ease in illustrating where I'm coming from. From what I can tell based on the Package Manager Console (see line numbers 19, 23, 25 and 28 below) I have .NET Core 2.2, am I correct? If I already have .NET Core 2.2, then I wonder what am I missing that is preventing a successful program run?
To make sure I am not missing any detail in showing what I am seeing, I have uploaded the full solution to github shown in the link:
If I uninstall then reinstall things in a trial and error fashion hoping that somehow things can get fixed, I can actually do more harm than good, so I do not wish to pretend having significant experience
installing Visual Studio and .NET Core 2.2; instead I'd like to ask the guidance of experts here who have more experience than I do in this area.

Please don't repost if your question does not appear immediately: all of these went to moderation and required a human being to review them for publication.

Thanks for your suggestion I will keep it in mind and make sure I do it as soon as I am able to move to Windows 10. Currently, I do not have much choice except to stick around with Windows 8 whose tools are no longer supported.
As an update, I looked at the error message closer and noticed I am running Microsoft .NET Framework Version 4.7.02053 on Microsoft Visual Studio 2017, using SDK 2.2.207 (from the Microsoft download site Download .NET Core 2.2), and therein I think lies the problem.
I can't believe it skipped my eyes that SDK 2.2.207 has Visual Studio support for Visual Studio 2019 so obviously the SDK I should have installed was SDK 2.2.110 as it is the one carrying Visual Studio support for Visual Studio 2017 not SDK 2.2.207 so it's my bad.
Can I uninstall SDK 2.2.207 and restart and then install SDK 2.2.110 without any problem?
But, because of relational nature of my tables, I need to specify userId when creating a new row in PM table. How can I set Foreign Key? I can detect userId using Session object but I don't know how to insert it in the table.
I want to have two ReportViewer controls in my VS project. I have two completely different types of reports and I want to split them between two RepportViewers that would be processed in two ReportViewer.aspx.cs. I have create copies of three files:
I am trying to create a site on IIS that can allow users to manually thru their mobile phones (yes they will have access to this internal site), and use their AD username/password to login. Anyone that's valid is allowed in. Once authenticated will present the next page. Plus that next page wouldn't allow them on it unless they are authenticated. Does anyone have any sample ASP.NET Web examples to get me started? Don't usually develop applications within IIS other than HTML pages so looking for any samples to get me started. Having a hard time finding one that isn't how to use Azure online.
The DataFormatString value is a format string to convert a date to a string in the format shown. The zero gives the position of the data parameter (following the format string) when the format is used, like:
I get what you want to do here, which is to create models to match your database perhaps, so each table has a matching model. But your over thinking this, and don't need that much detail. Keep it simple and flexible at first, and only add detail when needed. For some reason Microsoft likes to capitalize the first letter, and will nag you later about the first letter being lower case.
This is an example model in c# to match a DB table or collection. Your example is a like a model used to present data in the view. Even when presenting data in the view, I would keep that simple as well. You want to craft models as simple as possible, and try to make them as reusable as possible to keep models down in count.
I created Migration, but when I try to update database, the following error is occured:
