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

Live online training course - classroom version also available

£795 + 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.

"I really enjoyed the course. I thought the pace and content was perfect for an introduction, I learnt a lot from it. The trainer was very clear in his explanation, thought he was great in encouraging conversation etc to build rapport with the group. (SQL) I found the course to be engaging, relatable and very well structured. The trainer was great in his explanations and always made time for any questions we had. (SSRS) "

Anton Breen (Live Nation (Music) UK Limited)

"Superb course with a great and thorough trainer. Really enjoyable."

David Cohen (UP Global Sourcing (UK) Ltd)

"I thought this was a really good course and would definitely recommend. It helped that there were only three of us and I felt I could ask questions at any point. The course content was good and covered Power BI really well. The trainer was also really nice and gave us the opportunity to talk to him, before or after the course if we needed a hand with anything."

Banita Mistry (Valuation Office Agency)

"Really useful course. Excellent trainer; he paced the day well and even with the challenge of online training he was able to keep everyone engaged and made sure to reach out to ensure no-one was struggling/falling behind. The content was useful and gave a good grasp of the system and all the capabilities."

Rebecca Hughes (Mizkan Euro Ltd)

"Really good course, went at a good pace and covered everything that I wanted it to. I feel much more confident using Power BI and have a better understanding of what applications it can be used for. The trainer was great, he was very knowledgeable and made the course enjoyable!"

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:

A computer (obviously) running Windows.
A good internet connection.
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 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).
