Is AWS AppSync available for Xamarin? - xamarin

Although I see the SDK here
Github : https://github.com/aws/aws-sdk-net/tree/master/sdk/src/Services/AppSync
Nuget : https://www.nuget.org/packages/AWSSDK.AppSync
I do not see any sample apps using the AppSync for Xamarin or even .NET on Google. Is this really available or just a placeholder Nuget module?
If this is available, can anyone point me to a sample code?
Thank

Implement Mastercard Gateway Android SDK in Xamarin.Forms

I am trying to implement the Mastercard Gateway Android SDK in Xamarin.Forms but according to the documentation I need to edit the gradle.properties file which is not present in Xamarin.Forms. Is it possible for me to implement this SDK and if so how? What nuget packages do I need? I currently have the Com.MasterCard.Sdk, Com.Mastercard.Psp.Payment and MasterCard.Core packages I'm using Visual Studio 2019
EDIT: The payment gateway in question: https://github.com/Mastercard-Gateway/gateway-android-sdk

It’s possible convert Xamarin Forms app to Nuget package?

I developed Xamarin Forms app with Android and iOS platforms. I would like to know if it’s possible convert this app in a nuget package and run my app in other app.
Of course it would be a nuget package per platform.
I know that importing one project into another can, but I want to protect code. I also don't know if nuget packages can have UI.
Can you help me??
many thanks!!

Calling formflow from LUIS in bot framework 4.0

I need to call the formflow from LUIS using bot framework 4.0. Is it possible to do? If anyone has done it before please share reference links.
Thanks,
Sheveta
I am not sure exactly what you are trying to achieve here, but FormFlow has been deprecated from the core SDK as of v4. It is however available via the Bot Builder Community project on GitHub over at https://github.com/BotBuilderCommunity/botbuilder-community-dotnet or via NuGet at https://www.nuget.org/packages/Bot.Builder.Community.Dialogs.FormFlow/
FormFlows are removed from the Bot Framework SDK v4, they were an essential part of SDK v3 nonetheless.
However if you want to mimic the functionality of FormFlows the closest you can get using purely SDK v4 is by using Waterfall dialogs which are like mini dialogs prompted at each step.
And also like Gary said, you can use the Bot.Builder.Community.Dialogs.FormFlow nuget package for getting a port into SDK v4.

Could not install package 'FormsPinView 1.1.0'. in Xamarin forms

I am trying to install Device LockScreen FormsPinView package in Xamarin forms using PCL but its not install in my PCL project.
and facing the below error while doing so.
Could not install package 'FormsPinView 1.1.0'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile111', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
Any help is appreciated.
Convert your project to .NET Standard 2.0 it will solve the issue described above and will help you in many other ways. There are 4 simple steps that you have to make and they are described in this gist, however if you are using Visual Studio for Mac you could automate the conversation process by using extension called Mutation.
You can find more details on the official Xamarin blog.
I also wrote a short article on this topic.
Good luck.

How to use XLABS FrameWork

I have tried downloaded XLABS (https://github.com/XLabs/Xamarin-Forms-Labs) and try to execute it but its generate error. "System" not found. "Xamarin.Forms" not found. blah blah blah.......
I have tried to resolved it and finally execute it in Android Simulator, but its crash while launching.

Its would be great if anyone suggest, any help document or readymade sample using XLABS to download.
Thanks in advance for time.
Waiting for reply

XLabs is no longer maintained and they state it may no longer work with newer versions of Xamarin Forms.
I would recommend using FreshMvvm as an MVVM framework.
It was specifically designed to work with Xamarin Forms and I have successfully used it on 3 recent projects.
Here is a starter guide
