How to create a Xamarin.Forms Windows phone 8.1 project? - xamarin.forms

I cannot find a Visual Studio 2017 project for making Xamarin.Forms Windows 8.1 apps. How do I install it?

Windows 8.1 Silverlight and RT are all deprecated. I would suggest doing a UWP app and targeting Windows 10 instead.
However, if you do want to do a Windows 8.1 project. Make sure you download the Windows 8.1 SDK, then create a new Xamarin.Forms project. Then you will have to add a new Windows 8.1 project afterwards, and manually add the Xamarin.Forms Init code, in the project.
You can have a look at XArch for an example.
But once again, I strongly recommend against, creating a Windows 8.1 project, and you should do UWP instead.

Mobile blazor bindings

Can I use .net standard 2.1 with the last Mobile blazor bindings -Version 0.5.50-preview? I also want to use Xamarin forms 5 in the project. Is it possible to use Mobile blazor bindings with the Xamarin Forms 5?
Yes you could.
To get started, all you need is the .NET Core 3.0 or 3.1 SDK, Visual Studio or Visual Studio for Mac, and the ASP.NET and web development and Mobile development with .NET (Xamarin.Forms) workloads installed.
Install the templates by running this command from a command/shell window:
dotnet new -i Microsoft.MobileBlazorBindings.Templates::0.5.50-preview
And then create your first project by running this command:
dotnet new mobileblazorbindings -o FirstMobileBlazorBindingsApp
Open the solution (SLN file) in Visual Studio and mark either the Android or iOS project as the StartUp Project.
The more you could refer to the official doc.

Using UWP api in windows phone 8.1 app on windows 10 mobile

I would like to use the UWP clipboard api of windows 10 in my windows phone 8.1 winrt app.
I couldn't load the Winmd file by using Assembly.Load(string assemblyname) method.
Is there another way to use it. Please some one point me in the right way. I'm not very experienced in reflection.
Thank you
No way to use functionality from the Windows 10 SDK in an app using the Windows 8.1 SDK.

Could not find SDK SQLite.WP80 Xamarin and Azure build error

I am building an Azure app with Xamarin.Forms in Visual Studio 2015. My app is happily using both "Azure Mobile Services SQLiteStore" and "Windows Azure Mobile Services" in the Android and iOS builds. However, I am trying to get the same to build and run on WinPhone with little luck. I have tried various things, but typically end up with the following error:
Could not find SDK "SQLite.WP80, version=3.8.7.2". C:\Program Files
(x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets 1886
5 MyApp.WinPhone
Does anybody have a reliable set of instructions for getting Azure Mobile Services SQLiteStore operational on WinPhone 8.0 ?
In my case I had 2 problems
The reference to the SQLite for Windows Phone was missed in the WindowPhone App
As InitLipton said it's necessary to install SQLite for Windows Runtime depended on the windows phone version you are using (In my case was WP Runtime 8)
here are links of the runtime SDKs
WP Runtime 8
Windows Runtime 8.1

ASP.NET 4.5 is not registered after upgrading to Windows 10

I have a WCF web service which was working on Windows 8.1. After upgrading to Windows 10, I noticed that the IIS is not installed anymore. So I installed it along with ASP.NET 4.6 in Windows features. Now, when I open the project in VS2013 it says that ASP.NET 4.5 is not registered. Shouldn't it work with ASP.NET 4.6?
I had the same issue and was able to fix it by installing Visual Studio 2013 Service Pack 5 (the latest at that time).
You can download it from here:
https://www.visualstudio.com/en-us/news/vs2013-update5-vs.aspx
Make sure to select the right version according to the Visual Studio version you have.
