SharpLab Online Tool – Reveal what happens during compilation of C#

SharpLab is a .NET code playground that shows intermediate steps and results of code compilation. Some language features are thin wrappers on top of other features — e.g. using() becomes try/finally. SharpLab allows you to see the code as compiler sees it, and get a better understanding of .NET languages.

Recent versions include experimental support for running code, with some limitations.

Retry and fault handling in C# .NET

Sometimes you need to implement some sort of retry logic if an error occurs in a c# program.

Existing libraries for retry and fault handling:

Working with Equals() and GetHashCode() to compare your objects in C#

In general these interfaces and methods are good to implement when working with comparing objects of the same type in C#:

Interfaces:
System.IEquatable<T> – strongly typed implementation
IComparable<T> – strongly typed implementation

Override methods:
An override of Object.Equals(Object).
An override of Object.GetHashCode().
An override of Object.ToString() is usually a good idea.
Operator overloads for operator == and operator !=.

General rule of GetHashCode():
If two objects is equal then their hashvalues should be the same.
E.g.:
If Equals == true then
x.GetHashCode() == y.GetHashCode()
GetHashCode() is frequently used by collections like Dictionary<Key, Value> and HashSet<T>

How to Check AD Group Membership using cmd/powershell

Active Directory security groups are used to grant users’ permissions to various domain services and resources. Therefore, to understand what permissions are assigned to a specific user in the AD domain, it is enough to look at the groups in which the user account is a member.

My Ultimate PowerShell prompt with Oh My Posh and the Windows Terminal – Scott Hanselman’s Blog

I’ve long blogged about my love of setting up a nice terminal, getting the prompt just right, setting my colors, fonts, glyphs, and more. Here’s some of my posts.
…

I want to take a moment to update my pretty prompt post with a little more detail and a more complex PowerShell $PROFILE, due to some changes in Oh My Posh, PowerShell, and the Windows Terminal. I doubt that this post is perfect and I’m sure there’s stuff here that is a little extra. But I like it, and this post will serve as my “setting up a new machine” post until I get around to writing a script to do all this for me in one line.

I love my prompt.
