This is a very simple console application that I completed for a class assignment. It is shown here to illustrate my coding style, structure, and commenting. This example is considered Level 1 – Easy. The application should ask the user for the name, age, and gender of a pet (or any animal). The values are to be saved in the program and then the program should display the information back to user.
Security-Constrained Unit Commitment Programming Project
Source Code for 'Pro C# 9 with .NET 5' by Andrew Troelsen and Philip Japikse
Simple PERL script to import a CSV file (contains records of data - could be a dump from a database), execute custom SQL, and write back to a CSV file.
Concurrency and Instancing in WCF Services – A Demo of Service Concurrency and Instancing Behaviors with Multi-threading Clients: This project presents a simple Demo WCF Service and “Tester” Client Application demonstration that implements concurrency and instancing behaviors on a service with multiple client thread calls to a method on the service. The Demo Service is a standard template WCF service application hosted by the development IIS. The service features one simple method… a test method that simulates a long running process (it sleeps for 3 seconds). The client “tester” is a simple console application that creates multiple threads that access the service and report back on the results. The objective of this project was not to demo setup and hosting of a service, nor the client interface, but retrieve and display results of service behaviors with respect to multi-threaded access. Discussion regarding the hosting and setup of the simple IIS hosted service application will be skipped in this project article.
Simple Service Error Handler – A Demo of a WCF Self-Hosted Service & Client "Tester" Windows Form Application Exchanging Error Messages : This project presents a simple Math Service and Client Application demonstration that implements error handling on the service and communications of its errors to the client. The Math Service is a self-hosted (service host) WCF application launched and managed with a simple console interface. The client “tester” has a simplified GUI user interface to quickly demo and test the service (Windows Form Application). The GUI has features to add, subtract, multiply, and divide two numbers (integers). The GUI does basic data validation then sends a request to the math service. After it receives the results from the math service, it displays the calculation result or any received error messages (faults) to the user. The objective of this project was not to demo a calculator application but the handling of errors on a service.
Service Throttling in WCF Services – A Demo of Service Concurrency and Instance Throttling Behaviors with Multi-threading Clients: This project presents a simple Demo WCF Service and “Tester” Client Application demonstration that implements concurrency and instancing behaviors on a service with multiple client thread calls to a method on the service. The project also demos throttling service behaviors that are in the service configuration settings. Service throttling limits the client calls that could otherwise drain or slow down its service to other clients if too many are calling simultaneously. The Demo Service is a standard template WCF service application hosted by the development IIS. The service features one simple method… a test method that simulates a long running process (it sleeps for 5 seconds). The client “tester” is a simple console application that creates multiple threads that access the service and report back on the results. The objective of this project was not to demo setup and hosting of a service, nor the client interface, but retrieve and display results of service behaviors with respect to multi-threaded access. Discussion regarding the hosting and setup of the simple IIS hosted service application will be skipped in this project article.
WCF Simple Greeting Service Library & Service Host Console Application Supporting Http and TCP Protocols & Client “Tester" Console Application
This is a very simple Hello World program
ASP.NET Web API Student Service CRUD Demo with XML Datastore & Client "Tester" Console Application
Technical writing samples from college, professional courses, etc. Due to non-disclosure I cannot show my many technical reports done for former employers and clients.
This is a very simple console application that I completed for a class assignment. It is shown here to illustrate my coding style, structure, and commenting. This example is considered Level 1 – Easy. The application displays temperature conversion tables.
Write a Windows Form Application that saves a list of items. Every item has the following data: Description Amount Unit An example: “Buy milk 2 gallons”. “Buy milk” is saved as description, 2 as amount and gallons as unit. The basic requirement is that GUI should allow the user to add a new item, but for a grade A, the user should also be able to change or delete an existing item. The GUI should also present a list of all items saved in the registry. The list is to be updated after every change in the registry.

My Room – A Demo Virtual Reality (VR) App – Google Cardboard – Gaze Selection System – Interactive UI, Locomotion, User Interactions, and more
This project presents a Visual Studio solution including a simple demo WCF Authentication Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the user registration, login, logout, and service operations. In addition to demonstrating standard authentication capabilities, the WCF service implements a custom username and password validator pattern. Passwords are stored securely using Password-Based Key Derivation Function PBKD cryptology of which the implementation is discussed. A custom error handler ensures that exceptions are properly wrapped into WCF Faults and communicated to the client caller. Certificates are discussed along with how to implement a server certificate on a client machine for development testing of “integrity” and application trust. The project includes a demo certificate and script for generating self-signed dev certificates, which must be installed into the client certificate store for the client tester application to trust and access the demo service. The client “tester” windows form application is not intended as a UX/UI demo but used to test and verify that the backend authentication service registration, login, logout, service operations, and callbacks are working as expected and sending proper WCF fault messages. Lastly, the project is shown in the demo section with a video and screen captures.
WCF Math Service Library with Multi-Threaded Capabilities & Console Service Host and a Client “Tester” ChannelFactory Implementation
This project presents two separate WCF Service Applications and a client "tester" console application in the same Visual Studio solution. The WCF Services were hosted using IIS Express. A simple console "test" application connects to both of the services through separate proxy references. There are two services: school service (the main demo) and a basic math service.
This project presents a WCF Stock Service Library (StockServiceLib) that mimics a stock exchange. The service is implemented as a “singleton” and maintains persistent data between client calls and can handle multiple client sessions. The service is hosted via a console application (StockServiceHost). The client and service participate in a bi-directional/callback relationship. The client (StockClient) uses the ChannelFactory pattern as opposed to “Add Service Reference” with SVCUTIL. The client and service share a common assembly (SharedLib) that contains the key contract and data model information. Furthermore, a Utilities project is used by the client console application to facilitate user data entry and the complicated details of building and managing the WCF ChannelFactory connection implementation. The ProxyGen class inside the Utilities project abstracts the details of implementing and managing a generic ChannelFactory connection to a generic service for a client. Note: The Utilities project library was included as base code for my lab project to facilitate speedy completion; we were not expected to code this Utilities project ourselves due to complexity and time constraints. The remaining projects in the solution (SharedLib, StockClient, StockServiceHost, and StockServiceLib), I completed individually per requirements for the lab project.
This project presents a Visual Studio solution including a simple demo ASP.Net Web API Basic Authentication Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the Web API with CRUD operations (GET, POST, PUT, DELETE) that service design requires authentication (except the Get). In addition to demonstrating standard CRUD capabilities, the Web API service implements a .Net Memory Cache (MemoryCache) and custom username and password validator. Passwords are stored securely using Password-Based Key Derivation Function PBKD cryptology. The client “tester” windows form application is not intended as a UX/UI demo but used to test and verify that the backend authentication service allows the user to register with a username and password and verify the Web API CRUD functions based on basic authentication scheme. Lastly, the project is shown in the demo section with a video and screen captures. Note: Every Web API Authentication service should use secure transport. For brevity, this demo project does not implement or discuss the complicated detail nature of SSL/TLS.
This project presents a Visual Studio solution including a simple demo ASP.Net Web API Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the Web API with CRUD operations (GET, POST, PUT, DELETE). In addition to demonstrating standard CRUD capabilities, the Web API service implements a .Net Memory Cache (MemoryCache). The client “tester” application also allows the user to verify that the memory cache is implemented correctly and expiring per the set policy. Discussion of the memory cache implementation may help the reader with tips to understand, correctly implement, and verify the cache is expiring. Lastly, the project is shown in the demo section with a video and screen captures.
