## Overview

This repository is a collection of independent CliffTech .NET and Azure tutorial projects, not one deployed application. The main request-to-result patterns shown in the sampled code are API controllers delegating to services or repositories, with some examples adding validation, persistence, caching, authentication, or a React client. The graph highlights those patterns and other substantial projects evident in the tree; links for unsampled implementations are omitted rather than inferred.

Main entry points: [`dotnet9-crash-course/dotnet9-crash-course/Controllers/ProductController.cs`](https://github.com/clifftech123/clifftechyoutube/blob/main/dotnet9-crash-course/dotnet9-crash-course/Controllers/ProductController.cs) (Product API), [`dotnetBlazorFullStuck/dotnetBlazorFullStuck.ApiService/Controllers/CountryDataController.cs`](https://github.com/clifftech123/clifftechyoutube/blob/main/dotnetBlazorFullStuck/dotnetBlazorFullStuck.ApiService/Controllers/CountryDataController.cs) (Country data API), [`QueryableIEnumerableAPI/QueryableIEnumerableAPI/Controllers/EmployeesController.cs`](https://github.com/clifftech123/clifftechyoutube/blob/main/QueryableIEnumerableAPI/QueryableIEnumerableAPI/Controllers/EmployeesController.cs) (Employee API), [`DotnetAzureCosmosDb/DotnetAzureCosmosDb/Controllers/StudentController.cs`](https://github.com/clifftech123/clifftechyoutube/blob/main/DotnetAzureCosmosDb/DotnetAzureCosmosDb/Controllers/StudentController.cs) (Cosmos student API)
