Interview Question .NET Terminology Part 2

Q1. What is the CLI? Is it the same as the CLR?

The CLI (Common Language Infrastructure) is the definition of the fundamentals of the .NET framework - the Common Type System (CTS), metadata, the Virtual Execution Environment (VES) and its use of intermediate language (IL), and the support of multiple programming languages via the Common Language Specification (CLS). The CLI is documented through ECMA - see for more details.

Vacancy Interview Question

Q1. ‘Tell me what you know about this organisation.’

There is no excuse for not having a response to this question as it often comes up. Whatever the particular job that you are applying for, the interviewer will expect you to have some knowledge of the organisation, and the more the better.

Ad hoc Discovery

In this article we will add an ad hoc discovery mechanism to the DiscoveryChat program using System.ServiceModel.Discovery, an implementation of the WS-Discovery protocol.  In order for a service to be discoverable in an ad hoc manner it needs to respond to incoming probe messages. Ad hoc discovery implies that these probe messages come in through a well known port over UDP multicast.

Interview Question .NET Frame Work Part 1

Q1. What is .NET?

.NET is a general-purpose software development platform, similar to Java. At its core is a virtual machine that turns intermediate language (IL) into machine code. High-level language compilers for C#, VB.NET and C++ are provided to turn source code into IL.

Hosted Designer

What if we wanted to create a custom activity like the PrePostSequence and have someone else who does not have Visual Studio use it? Many products allow end users to customize workflows. Windows Workflow Foundation 4 allows us to host the designer in an application quite easily. In this article, we will host the designer and use your custom activity.

General Interview Question Part 2

Q9. ‘What other careers are you interested in?’

If you are applying for a computer operator’s job in order to pay the rent and secretly want to be a police officer or a ballet dancer, keep that to yourself. Again, think – why is the employer interested in this question? He or she will be most impressed by the candidate who seems serious about the job on offer and about making a career in this line of work. Talk more about your interest in this work. What attracted you to
apply and why do you think you are suitable for it? Imply that your career ambitions are in this exact field. You could add that in the future you would be interested in working your way up to a position with more responsibility, or perhaps specializing in a particular area of the work.

General Interview Question Part 1

Q1. ‘What hobbies or interests do you have?’

Why should employers be interested in the answer to this question? Is it pure nosiness? Everything you say about yourself contributes to the general impression gained about you. If I tell you that my hobbies are knitting, cookery, needlework, decorating cakes and bird-watching, you have an idea of the sort of person I am. If, however, I tell you that my hobbies include karate, African music, organising a community group, gardening and swimming, the picture is quite different.

Error Handling

In the previous post Adding If / Else Logic We may have noticed a potential bug in our simple application. What happens if we don't pass a UserName to the workflow? In this article, we will add some error handling capabilities to our workflow by using the Try/Catch, Catch<T> and Throw built-in activities.

Adding If / Else Logic

In the previous post Workflow Application part2 we created an enhanced Hello Workflow application with a custom hello message. In this post, we will add If/Else logic to the workflow to display a different Hello message depending on a custom condition.

Employment History Interview Question Part 1

Q1. ‘Have you had any work experience?’

This question is often asked of younger people who have just left full-time education. No employer wants to hear that you are completely inexperienced, even if you only left college a week ago. If you took part in any practical placements at college, talk about them here. You will need to come up with some kind of answer in order to reassure the interviewer that you are used to the routine of work, that you can hold down a position and that someone else has wanted to employ you in the past. Perhaps you have done a paper round; worked on voluntary projects while at school; had holiday or vacation jobs or participated in a work experience program at school or college.

Employment History Interview Question Part 2

Q8. ‘What will your last employer say about you if we ask for a reference?’

You may get asked this question even if your last employer has already filled in a reference. The interviewer wants to know about two things: first how well you got on in the last job and second, how you think other people see you. Talk up about your strong points in your answer, particularly those that will be useful in the job for which you are being interviewed. You can include negative points as long as they don’t detract from the overall positive image you are trying to create. You could say that your old boss might think that you
could be quite direct in your opinions sometimes but that you know he always valued your honest feedback. Or that your old supervisor might describe you as being the life and soul of the work team but that when there was a crisis you would be the first to volunteer to help out.

Workflow Application part2

Our project is good but it has one weakness. It verifies that the WorkflowThread returned is non-zero but it does not verify that it returns the actual managed thread ID that the workflow ran on. Our project would pass if the workflow always returned 1.
