Visual Studio Nuget Package Restore Error - The type or namespace name 'Xamarin' could not be found

-
Good evening,

Recently, I encountered an error called "The type or namespace name 'Xamarin' could not be found (are you missing a using directive or an assembly reference?)" when running my simple Xamarin Forms application in Visual Studio 2019 which is the output of the training I attended with. It seems that the project is missing some references and when running the solution, the project was unable to download the missing assemblies. After investigating the problem, I found the culprit. Our custom Nuget packages were located in a server which has been turned off due to system upgrades and these files will be moved to a new location. So to fix the issue I had to perform the steps below:
1. Temporarily unchecked our custom built packages in Package Sources of Package Manager Settings since our server that contains those packages was turned off for system maintenance and the projects including the packages will be moved to a new location.
The type or namespace name 'Xamarin' could not be found (are you missing a using directive or an assembly reference?)

2. Run the command "Update-Package –reinstall" in Nuget Package Manager Console to restore all packages for the current Xamarin Project or I could have rebuild the solution to restore the missing packages.

Cheers!

How To Insert Or Add Emojis In Microsoft Teams Status Message

Good day Gents! I was trying to update my Microsoft Teams status and was wondering if I can add or insert emoji. For editing or adding new teams status, only text fields are available and there's no emoji icon similar to writing a teams message. After googling for a few minutes, I found this link Emoji's in status which is a feature request in Microsoft Teams User's Voice Forum. So far this upgrade request only has thirty votes which is relatively small and may be considered a low priority for the product team to implement. Given the limitations at hand, I tried several approach including copying an emoji in a chat message which didn't work and later found a solution using Microsoft Outlook 365. First is to create a new email message in Microsoft Outlook and press (Window Key + .). The emoji dropdown control will appear. Next is to select the emoji that you wanted to add to Teams. Copy the emoji from the newly created email message template and paste that to Micr

Good afternoon fellow developers! I have been working with Bootstrap Modals before and it's time to demonstrate its significance using a simple ASP.NET MVC CRUD (Create Update Delete) application project using Entity Framework Database First approach. First is to create a basic BookDetails table on your SQL Server instance. USE [DemoDB] GO /****** Object: Table [dbo].[BookDetails] Script Date: 11/2/2020 12:26:53 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[BookDetails]( [BookSerialNo] [int] IDENTITY (1,1) NOT NULL , [BookISBN] [ nchar ](15) NULL , [BookTitle] [varchar](120) NULL , [BookAuthor] [varchar](60) NULL , [BookPublisher] [varchar](50) NULL , [BookCategory] [varchar](20) NULL , PRIMARY KEY CLUSTERED ( [BookSerialNo] ASC ) WITH (PAD_INDEX = OFF , STATISTICS_NORECOMPUTE = OFF , IGNORE_DUP_KEY = OFF , ALLOW_ROW_LOCKS = ON , ALLOW_PAGE_LOCKS = ON ) ON [ PRIMARY ] ) ON [ PRIMARY ] GO Next is to create an ASP.
