I have a project built in SharePoint 2013. I have a SPDataSource as Base class in my project. I have a reference to the Microsoft.SharePoint.dll file but still this SPDataSource and SPDataSourceView are giving me error.
Missing Namespace error
Severity Code Description Project File Line Suppression State
Error CS0246 The type or namespace name 'SPDataSource' could not be found (are you missing a using directive or an assembly reference?)
Can anybody tell me why is this?
Thanks in advance
Create a new project from inside visual studio from the Templates -> Office/SharePoint -> SharePoint 2013 Empty project.
From there compare the references between that and your project.

The first error is concerned soap service but I can't resolve it.
The second error is concerned the Resources project that has the App_GlobalResources package.
Please help me to fix these errors. I think it's ABC in programming.

Try uninstalling (if installed) EntityFramework and re-installing. Failing that, please post what references you currently have.

Your compiler tells you, that you are missing some references. Most likely you are missing some assemblies.
Check under References if both assemblies are available. Do they have an yellow warning sign? If yes, visual studio can not resolve the path to the assembly or the assembly is just missing.
You have to provide some more details about your setup or configuration of the project to determine the situation.
I've created a new 'Blank Xaml App (Xamarin.Forms Shared)' app in Microsoft Visual Studio Enterprise 2015 version 14.0.25123.00 Update 2.
Immediately after creating the project, I was greeted with 217 errors.
Restarting Visual Studio removed most of those, but 35 still remain.
The first two errors are about Foundation and UIKit not being found. I believe these two might also cause the rest of the errors.
Does anyone have some ideas as to how to solve these?

If you are missing the reference to Xamarin.iOS, try re-adding it manually:
Under the Xamarin.iOS project, right click References > Add Reference...
In the references dialog, on the left hand side, click on Assemblies, then Framework. Search for Xamarin.iOS and select it to add the reference.
If the Xamarin.iOS assembly isn't listed, take a look under this path:
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Xamarin.iOS\v1.0
If the assembly is missing from that directory, try repairing the Xamarin installation - Windows Programs and Features > Xamarin > Repair.
