.net portal required for front end development? - frontend

this maybe a naive question but i thought i should ask this. so i saw a front end developer job ad and the requirements were like this:
I googled .net portal but what shows is .net framework which to my understanding(correct me if i am wrong) is mainly used for c# programming language.
my question is, what is a .net portal?

I am guess they mean .NET Framework.
I have not come across .NET portal yet during my years of programming.

Is there an API for the Azure Language Studio, especially for Custom Question Answering?

i am currently working with the Language Studio by Azure. For now, i am wondering if there is an API for this, especially for the Custom Question Answering that i can work with on my current project.
Language Studio is just a demonstrator. Everything is made thanks to APIs.
For example for Question answering: https://learn.microsoft.com/en-US/rest/api/cognitiveservices/questionanswering/question-answering

1.14 SDK and Devices.PointofService relationship?

I can't find an answer to this question:
Is Windows.Devices.PointOfService API and the POS for .NET v1.14 SDK the same thing? Both contain LineDisplay.
What is the relationship between the two?
TIA
Harry
The POS for .NET v1.14 SDK is for developing .NET application. It cannot be used in UWP app programming. The document POS for .NET v1.14.1 SDK Documentation also has mentioned this point.
POS for .NET does not provide any support for the Windows Runtime (WinRT) API.
If you're developing UWP app, you need to use Windows.Devices.PointOfService Namespace APIs.

Can WPF applications be run in Linux or Mac with .Net Core 3?

Microsoft announced .NET Core 3 comes with WPF and Windows Forms. So can I create a desktop application for Linux or Mac using .NET Core 3?
No, they have clearly stated that these are windows only. In one of the .NET Core 3.0 discussions, they have also clarified that they do not intend to make these features cross-platform in the future since the whole concept is derived from windows specific features. They talked about thinking of a whole new idea for cross-platform applications, which is not easy.

Update
The newly announced .NET 5 now aims in avoiding all this confusion by no longer calling it ".NET Core".
Update 2
With blazor client-side (releases on may, 2020), there is a new experimental project for cross-platform apps using webview that is in the works.

No with WPF or Winforms. But you still can develop desktop apps on Linux, with .NET Core, using other libs like GtkSharp or Avalonia
Well, the name itself says Windows Presentation Foundation. So it's primarily windows based.
But it is worth to be noted that the new UI framework, .NET MAUI that will be shipped with .NET 6 is cross-platform, with a single-codebase, single-project structure.
Currently in Preview at the time of writing, to be shipped in November 2021. Here's the roadmap.
Although it is not native dotnet core on linux, but it may be helpful - using wine.
I find a very useful comment in the discussion here, more details here
In other words, it is possible to use windows version of dotnet core under wine.
I didn't try it yet, but from the article I mentioned I can say it looks nice and might be an option.

VS2015 Properly Targeting .Net Framework 4.6.1 with new Web Application Project or Class Library

I've created a new Web Application Project in VS2015 using the newer aspnet5 templates. However I can't seem to find a straight answer on how to specifically target the .NET 4.6.1 Framework with it. Looking at the pictures below can someone please shed some light on how to use the newer prject structures but target the .NET Framework 4.6.1 with them. According to microsoft this is possible but I can't make heads or tails on specifically how to do this.
The old and new ways are shown below.
The new way below shows use specific runtime...
With the following showing in the references
The old way seemed much more straight forward. Showing a specifically targeted framework.
The same problem exist for Class Library projects where it seems to want to target an SDK vs a particular version of the framework.
I believe you need to set your DNX_IIS_RUNTIME_FRAMEWORK environment variable to "DNX461". I found this question relevant.

Using Async with MVC4 and Azure

I'm watching this lecture http://channel9.msdn.com/Events/TechDays/Techdays-2012-the-Netherlands/2287 and on 14:08 he says that MVC4 has the Async feature. I have VS2010 with MVC4 beta installed, but doesn't have the Async available.
After doing some search I understaand that to use Async you need VS11 and what is more important that here https://www.windowsazure.com/en-us/develop/vs11/ they tell that Azure doesn't support VS11 projects yet.
This is very confusing because in the video he does not tell that I need VS11 and I can't tell from the UI if it is VS11.
So my question is there a way how can I TODAY use Async + MVC4 on Azure?
There's a CTP that you could install and which enables this feature in VS2010. It stays CTP though. The feature will be part of the .NET 4.5 framework and available with VS11.
If you need to use the new MVC 4 and .Net 4.5 features on Azure, please go to the Azure UserVoice site and vote for this feature: http://www.mygreatwindowsazureidea.com/forums/34192-windows-azure-feature-voting/suggestions/2598170-iis8-and-asp-net-4-5-support-in-azure-platform
