Uno Platform : Designs not displaying - visual-studio-2019

I am unable to view the designs of my code. Getting this message.
Visual Studio requires a newer version of Windows to display this
content. Please update to Windows 10,version 2004(10.0.19041.0) or
later.
I am currently running on Windows version 1909 and Visual Studio (Version 16.7.2)
There are no current windows updates available currently for my device.
Any insights to this will be valuable.Thanks

Well, the message is quite self-explanatory.
This functionality requires Windows 10 version 2004, whereas your system is currently at 1909. You won't be able to see the design view until you get the Windows update.
Hopefully this article can help you update your Windows version.

Is there a way to use DirectX 11 in Windows 7?

I was trying to start to learn programming in DirectX 11, but I'm still using Windows 7 OS. My IDE is Visual Studio Community 2019 and I've tried to create a DirectX 11 project, but I got the error message saying that I need to upgrade my system to Windows 10 to be able to use this feature. I've downloaded Microsoft Development Kit, SDK and another extensions VS offered to me thinking it would actually work, but it didnt. I'm sorry if this seems a silly question, but I'm new on this and I would find it a great help if someone is able to tell me what I'm doing wrong or if there is really not other way to program in DirectX 11 on windows 7.
As noted by Simon in the comments, the "DirectX" templates built-in to VS 2019 are for Universal Windows Platform (UWP) apps only which requires Windows 10.
I maintain a number of similar templates for UWP and Win32 for DirectX 11 & DirectX 12 on GitHub.
Windows 7 supports DirectX 11.0.
Windows 7 can support DirectX 11.1 "software features" but not "hardware features" with KB2670838. Basically this means you won't get D3D_FEATURE_LEVEL_11_1. See Microsoft Docs. Most any Windows 7 system that's updated from Windows Update should have it.
My Win32 templates assume you have DirectX 11.1 these days. For the details on handling DirectX 11.0, see this blog post.
VS 2019 can support targeting Windows 7 Service Pack 1 for Win32 desktop development. Officially Windows 7 RTM is not supported.
VS 2019 comes with the Windows 10 SDK which includes everything you need for basic Direct3D 11 system headers and libraries. You do not need the legacy DirectX SDK at all. That said, if your learning materials still reference legacy stuff like D3DX11, you can install it but beware there are some special setup details. See Microsoft Docs.
For XAudio2 on Windows 7 SP1, use the XAudio2Redist instead of the legacy DirectX SDK. For XInput, you can use the basic XInput 9.1.0 which is built-in to Windows 7.
You may want to take a look at the DirectX Tool Kit tutorials.

Xamarin iOS: Cannot render iOS Storyboard in Visual Studio 2013

I cannot see the story board in Visual Studio 2013, when I open it it tells me
There was a problem rendering this document.
Also in the errors list I have the following:
The clocks on the Build Host and this Machine are out of Sync. Please make sure they are within 3 minutes (UTC) of each other.
Failed to retrieve SDK status from server Xamarin.iOS Extension.
Also the output from the MAC server log tells me:
Error sending iOS designer payload
What can be wrong here?
I was also having a similar problem where I couldn't open the story board in Visual Studio 2012 or 2013 (I didn't have any errors in my error list, just the error when displaying the designer). My setup is dev work in Windows 7 with Visual Studio 2012/2013 with a Mac acting as a Build Host. I had just updated my Xamarin version from 3.0.54 to version 3.3.47 (it had been a little while) and I had created a little prototype app a couple days ago with no problems, so I figured I had killed something with the update.
In my case, the solution was checking for updates in Xamarin Studio on the Mac, where it found several that needed updated. After installing the updates on the Mac side, I was able to display my story board in both Visual Studio 2012/2013 without issues... so I chalked it up to version mismatch issues between the Build Host and my dev environment in Windows.

missing iphone option inside xamania studio

I am new to ios. I m just keen to learn iphone. So i installed Xamarin in my Windows 8.When tried to create a new file for iphone i did not get any option for iphone. I got only android,Asp.net under C#. So can anyone tell me what should i do now to get iphone option inside C#. Have i done anything wrong in installation. or it is not at all possible in windows 8.
I am following this
In windows machine by using only Xamarin Studio you can't do iOS development.
You can do this possible by using Visual Studio Non-Express Edition.This studio is extensible.Xamarin comes with iOS plugin for Visual Studio but only for its Non-Express Editions.
So,you will need to use non express edition of Visual Studio in order to get iOS plugin ready to work in your Windows 8 machine.Hope this helped you.

How can I get started with Xamarin from Visual Studio 2013?

I want to port a Compact Framework/Windows CE app to Xamarin to create Android and IOS (and possibly Windows Phone) "versions." I reckon I need Windows 8 for Windows Phone (8) but for now I thought I could get started with Android and IOS in moving this prehistoric app into the 21st century.
According to this article, I first need "Project linker" and can NuGet it, but searching for it via Tools > Extensions and Updates in VS 2013 returns no search results.
That article says you need VS 2012 or better; the direct link to "Project Linker," though, says it supports VS 2010.
Where do I go from here?
UPDATE
I went here, and am in the processing of downloading.
UPDATE 2
Here, it says, "Modern Integrated Development Environment (IDE) – Xamarin uses Xamarin Studio on Mac OS X, and also Xamarin Studio or Visual Studio 2010 on Windows."
Yet in VS 2013, I do have project types now for Android and IOS*, so I reckon that's just a typo (hasn't been updated)?
although I don't have a Mac, so that is not possible for me right now; also, since I'm still on Windows 7 at work, Windows 8 Phone apps are not yet a possibility, either. So at present, Xamarin within Visual Studio is simply a replacement for Eclipse/Java in the creation of Android apps.
UPDATE 3
I've been waiting for something better than PhoneGap, and I think maybe I've found it. If MS were to buy this company and bake Xamarin into Visual Studio -- voila!/yowza/wow! The cats in Cupertino will have to reach for the Pepto-Bismol!
That's a bit outdated and there's a much better approach available today.
You can use Portable Class Libraries (PCL) to share code across project spanning iOS, Android, Windows (Phones) and even OSX.
See this article (and where it leads) for more details.
I certainly agree with #poupou that PCL's are the way to go (if possible). I would recommend James Montemagno's app on github. He just created this for channel9 using VS 2013. I just created a cross-platform app based off of this and it worked out well. I would only use the file-linking for the platform specific implementations with compiler directives. This can be seen in his ServiceRegistrar class in said app.
This SO answer actually explains how to get the 2012 Project Linker to work with 2013 if you still want to go that route and gives a link to the extension.
Also, you may want to check out MvvmCross. It is open-source, has a large user-base and following, and really helps with maximum code re-use. Best part, it uses PCLs and all of it's features (plugins) are available via nuget.
I would recommend reading the article #poupou posted, watching James' channel9 videos on his github page, and (if you want to check out mvvmcross) watch #slodge's N+1 videos on mvvmcross.

Is there a way to install Delphi 2010 on Windows 2000

I just downloaded the Delphi 2010 iso from my SA-subscription and wanted to install it in addition to my other Delphi installations on my notebook computer. Unfortunately it refuses to install because the machine is running Windows 2000.
Is it possible somehow to get it to install it anyway? Or is there a technical reason why it might not work, even if it installed?
edit:
Some more information:
Delphi 2009 installed fine on that computer, so dotNET 2.0 is already installed.
The Delphi 2010 installer comes up, asks me for the language to use and then says "This product requires at least Windows XP. Setup cannot continue."
What I am looking for now, is either:
a way to get the installer to skip this check and install anyway - or -
a reason why this would not work (e.g. Delphi is using some Windows API that is not available in Windows 2000)
You could try to start the setup.exe with the /Win2K parameter. Maybe this helps. But I heard from a German forum that a user who installed Delphi 2010 into Windows 2000 had lots of problems with the IDE. So use the /Win2K parameter at your own risk.
And you must have at least .NET 2.0 SP1 installed
According to the minimum system requirements, Windows 2000 is not supported. They might use some XP+ specific API's these days, but then again they might not, as Delphi 2009 installed fine on Windows 2000.
The first thing you might want to check is if you have .Net (2.0 minimum) on your machine. According to the document linked above, they try to install The .Net 3.5 distributable otherwise, and that one definitely requires XP minimum.
windows 2000 is supported in Delphi 2010, check the following link:
Target Windows 2000, XP, Vista, and Windows 7 from single source
I think the problem is from your pc, maybe because there are other versions are installed, can you post the message?
