How to fix: No IntelliSense for .NET Core C# files in VSCode

When using the C# 1.17.1 Visual Studio Code extension, I didn’t get correct IntelliSense for C# files.

There was a problem with Omnisharp. It outputted the error found below.

I also had Visual Studio Community 2017 installed and the Visual Studio Build Tools.

After uninstalling the Visual Studio Build Tools. Visual Studio Code asked me to install necessary build tools, after clicking “Yes” to install, the problem was fixed.



Omnisharp error in VSCode: Could not load SDK Resolver. A manifest file exists, but the path to the SDK Resolver DLL file could not be found.

Fix Code Spell Checker extension NOT working in Visual Studio Code

I installed the code spell checker extension for Visual Studio Code

But the spell checker was not working, the status bar showed an exclamation mark icon.

For some reason the spell checker was disabled in the workspace settings:

After this setting was set to true and the workspace settings json file was saved, the code spell checker started working again.

How to scan a double sided document to one PDF by using the HP Color LaserJet Pro M477fdw

The HP Color LaserJet Pro M477fdw has a document feeder and it is able to scan a double sided (2-sided) document to one PDF leaving the pages as separate pages inside the PDF.

  • Install HP Scan (not HP Easy Scan).
  • Select Source = “Document Feeder if loaded”
  • Select Page Sides = “2 – sided (book)”


And now the important part, when clicking on the File Type “PDF” a new screen appears.


Make sure you disable / uncheck “Separate file for each scanned page”, then save the settings and scan the document.

The double sided document will be scanned to one PDF file with 2 pages in it.

Note: When you put multiple documents in the document feeder all sides of all pages will now be scanned to one PDF.
