Overview

The dotnet-core-examples repository contains samples that you can use to test various aspects of NET Core | ASP Net Core. Each section (folder) contains one or more applications that should run on any number of operating systems, each having their own Makefile to facilitate: clean, pack, install and uninstall. Most applications can run with a simple command: dotnet run. All the samples have been tested as .Net Global Tools.

The code for each application is Verbose, meaning, shortcuts and advanced concatenations have been kept to a minimum to allow for easier readability. Code comments are also brief, but should suffice for most readers.

The majority of the programs are a single file (Program.cs), easy to use, and can be compiled on any operating system capable of running .Net Core SDK.

All of the examples are layed out in sections (Folder Hierarchy). While the Database, WebMVC, and WebAPI sections are not listed as Advanced, the examples represent many challenging aspects of OOP including Dependency Injection, Models, Controllers, Views, and Database Integration.

Usability

At the time of this writing, all example applications were tested on:

• Oracle Linux 7 an 8
• Windows 11 Pro 23H2 22631.3007
• Windows Subsystem Linux (WSL)
• Linux Native Ubuntu 22.04
• If the .Net Core SDK can run on a particular system, so should the examples.

System Requirements

• Supported Operating Systems: Windows, Linux, MacOS
• Net Core SDK v8.0
• VS Code Editor is optional but preferred
• Dual Core CPU Minimum
• At Least 1GB RAM
• 1 to 2 GB of Free disk space (if running all apps, less if not)

NOTE: All tools in this repository have been updated with Makefiles that support installing each application as a .Net Global Tool. This allows for global access to the application from anywhere within the user space. File install locations are as follows:

# Windows
C:\Users\%username%\.dotnet\tools

# Linux | MacOS
/home/$USER/.dotnet/tools

Installation Using Makefiles

Each application has its own Makefile with the commands to build, install, uninstall and run the application except where noted. For Windows, the file name is make.cmd. For Linux, the file name is Makefile without extension. In both cases, the invocation command is the same: make <target>.

# Install: In the directory you want to test, type the following:

# Windows
.\make.cmd clean
.\make.cmd pack
.\make.cmd install

# Linux | MacOSX
make
make install

# After install, type the name of the package you installed to execute it.
# Example: To start LBService, type:

LBService

# Upon successful installation, the appropriate application name will be
# displayed with instructions to run it.


# Uninstall: Windows
.\make.cmd uninstall
.\make.cmd clean

# Uninstall: Linux MacOS
make uninstall
make clean

Introductory Logic, Conditions, Loops

Basic Functions employ things such as Arrays, for-loops, while-loops, and if-else statements. All functions are contained within the standard (Program.cs) file. Typically, no other classes are involved apart basic from using statements.

Application	Type	Description
ComputeArray	Array	Compute average using an array.
SimpleArray	Array	Sum 10 entries from user
TargetValue	Array	Find target value in array
DoubleTriangle	for-loop	Print a diamond using loops
RightTriangle	for-loop	Print Right-Triangle using loops
RocketLaunch	for-loop	Simple count-down counter
SingleTree	for-loop	Prints a tree using loops
StackDifferent	for-loop	Stack Different Numbers Across
StackSame	for-loop	Stack Same Numbers Across
BasicMath	if-else	Sum, Difference, Quotient, Product, and Average
CorrectChange	if-else	Use Modulus to calculate correct change
EndsWell	if-else	Determine the suffix, for a given integer (1-100)
EndsWellExtend	if-else	Determine the suffix, for a given integer (1-1000)
FeetToYards	if-else	User Input feet => convert to yards
GradeDetermination	if-else	Determine letter grade from three input values
LeaguesToNm	if-else	User Input Leagues => convert to Nautical Miles
MiddleValue	if-else	Determine the middle value of three integers
MilesPerTank	if-else	Calculate Miles per Tank of Fuel
NetPayCalc	if-else	Calculate Net Pay by taking out fixed tax rates
PerfectFit	if-else	Determine various apsects of Squares and Rectangles

LargestNumber	while-loops	Loop entry, print largest number
PaymentPlan	while-loops	Loop payment plan comparison, no user input
PowerOff	while-loops	Loop that calculates powers of 10 for x < <= 10

Intermediate Structures, Methods and Functions

Intermediate employs things such as structures, and methods outside of the main method or (Program.cs) file.

Application	Type	Description
AreaOfCircle	methods	Use methods to calc the Area of a Circle
AreaOfTriangle	methods	Use methods to calc the Area of a Triangle
CalculatePay	methods	Use methods to calculate Gross Pay
InchesToCentimeters	methods	Use methods to Convert In. to Cn.

JobListing	struct	Use struct to generate job postings
MSLListing	struct	Use struct to add to listings array and MLS IDs
RandGen	struct	Advanced Password generator with user input options

Advanced Structures Methods and Classes

Advanced applications are a combination of both Basic and Intermediate functions. They may also use instantiation of classes, interfaces, abstracts, or more advanced Object Oriented Programming (OOP) techniques.

Application	Type	Description
EmployeeCommissionV1	various	Calculate commission for one or more employee's
EmployeeCommissionV2	various	Uses: Struct, Array of Struct, if-else, loops and methods
TikTakToe	various	Game: uses 2D Arrays, if-else, loops, methods, and colors
