Ive added the using Microsoft.SharePoint.Client;
But still getting errors, is it some dll i need to download?
This is the error:
The type or namespace name 'SharePoint' does not exist in the
namespace 'Microsoft' (are you missing an assembly reference?)
(are you missing an assembly reference?)
That's the important part. You say you have added a using statement for the namespace, but have you added an assembly reference?
First, you need the DLL. Next, right click your project's "References" section (Solution Explorer window), click "Add Reference" and then browse to the DLL. Add it and you should be set to go.

How fix it?
I had the same issue in a custom package after updating to 2020.2.3f1.
In the case of packages (or if you are using assemblies), they now seem to enforce that Editor's only assemblies should be marked as such in the Platforms section of the inspector:
Test code needs to be under Editor, so it compiles to the Assembly-CSharp-Editor-*.dll which has references to the nunit dlls.
I find this particularly confusing given a quick inspection of Assembly-CSharp-*.csproj will show the nunit.framework listed as a reference, and the fact that it will also build if you point msbuild at the generated solution within vscode (whilst simultaneously failing a Unity 'refresh').
I want to run the Xamarin project and did all the updates. When I run the project I get the following error
The type or namespace name 'Windows' could not be found (are you missing a using directive or an assembly reference?)
for the lines
using Windows.Storage;
using Windows.ApplicationModel.ExtendedExecution;
That's because you're missing these .dll
The recommended steps to get access to UWP APIs are listed in the dedicated blog post on Windows Blog.
Basically you can take two approaches: add the references to UWP dlls and winmd files manually or use the UwpDesktop NuGet package that will take care of this for you automatically.
For more details, you can check: How do I get access to Windows.Storage namespace?
I added System.Web.DataVisualization in my references folder but when I try to use it in a view like this
<img src="/Chart/CreateChart?chartType=#(System.Web.UI.DataVisualization.Charting.SeriesChartType.Column)"
I get this error
The type or namespace name 'DataVisualization' does not exist in the namespace 'System.Web.UI' (are you missing an assembly reference?)
It is, however, recognizable in my controller.
Remove the reference and re-add again.
I copied the System.Web.DataVisualization.dll in the bin folder of my project and it did work.
I have added in ComponentModel.Composition; assembly .But showing this error for
using System.ComponentModel.Composition;
and reference for the assembely
still gets the error
CS0234: The type or namespace name 'Composition' does not exist in the namespace 'System.ComponentModel' (are you missing an assembly reference?)
First of all (if it's needed) Open your project in Visual Studio 2012 or later, choose Manage NuGet Packages from the Project menu, and search online for the Microsoft.Composition package.
Right-click on your Project and select "Add Reference". Find System.ComponentModel in the Framework list and add it or the applicable sub assembly.
Thats's all I did when I faced this problem.
I added using Microsoft.VisualBasic to my code but compiler reports error CS0234:
The type or namespace name 'FileSystem' does not exist in the namespace 'Microsoft.VisualBasic' (are you missing an assembly reference?)
What is this "assembly reference" and how to add one?
Error also shown in the picture

You've got a using directive for the Microsoft.VisualBasic namespace, but the fact that you're fully-qualifying the name Microsoft.VisualBasic.FileSystem makes that irrelevant.
I suspect you just haven't added a reference to the Microsoft.VisualBasic.dll assembly. (Assemblies and namespaces are very different things.)
Personally I would attempt to avoid VB-specific assemblies in the first place, to be honest.
