Classroom training - Intermediate C#

Online Training

Intermediate C# training course - Classes, LINQ and Entity Frameworks

Live online training course - classroom version also available

£695 + VAT (where applicable)

Two days (09:30 to 16:30 UK time each day)

To learn to program in C#, you first need to learn the basics.  This course assumes that you've already done this (perhaps on our two-day Introduction to C# course), and that you're now ready for the second part of learning to program in C#: understanding classes.

Everyone takes a while to get used to creating and using classes, but in this course we try as hard as we possibly can to shorten the learning curve.  You'll learn how to:

  • Understand objects, properties and methods
  • Design classes
  • Create classes (including constructors and fields)
  • Use entity frameworks (EF) to connect to databases
  • Create queries using LINQ to connect with your databases

The course will use a database-first approach, use SQL Server as the underlying database and use Visual Studio as the development environment, but the same principles apply whichever EF approach, database and development environment you choose to use.

What other people have said

Many thanks to those listed below for kindly agreeing to let us use their names. All of the reviews are from the last 3 calendar years (although some may be for classroom courses):

"Superb job. One of the best courses I've been on. Fantastic trainer - very knowledgeable, hugely personable and an excellent presenter. We had a lot to cover in the three days. Not once did I feel rushed, not once was the instruction anything other than clear, well explained and very well organised. Kudos too to the people who write your manuals - they are excellent - clear, concise and easy to absorb. This is my second Wise Owl course and I will sing your praises to anyone who cares to listen. What makes the difference? The human touch and the thought and care. You're dealing with a person, not an opaque and convolution online registration process. A great deal of effort has gone in to the content of the courses and their manuals and above all they're delivered by likeable, knowledgeable people who want you to learn."

How our live online training courses work

We've published a full summary of what it's like to attend a Wise Owl course online - here are the main things you need to know.

What you'll need

You'll need three things for the course:

  1. A computer (obviously) running Windows.
  2. A good internet connection.
  3. A microphone and (ideally) webcam.

In addition you'll find the course very difficult without an additional monitor (so that you can participate in the course on one screen, and use the software you're learning on the other).

What will happen when you book a place

Within a few hours of your booking a place on one of our online courses, we'll be in touch to get you set up correctly.  This usually takes about half an hour, and can be done at any mutually convenient date/time.

A few days before your course begins you'll receive a parcel in the post (free for UK bookings) containing:

  • A full colour courseware manual;
  • An exercise booklet to go with the course; and
  • A USB stick containing the files for the course, should you need a back-up.

Your parcel will even include a Wise Owl Sheaffer biro (they're good; trust us) and pad.

What you won't need

You won't need to install any software at all on your computer.  This is because:

  • you'll use Windows Remote Desktop to connect to our computers, and these will have all of the necessary files and software installed; and
  • we use Teams for our online training, which you can run through most modern browsers.
On and after the course

On the day of the course itself you will be able to join the course up to half an hour before it begins. This will give you time to:

  • familiarise yourself with the set-up;
  • meet your trainer; and
  • get to know the other delegates!

After the course finishes you'll receive an electronic certificate proving your attendance (we will gladly send a paper copy on request also).
