Description
Welcome to Minimal API with .NET 10 and C#, the most comprehensive and practical course available for mastering modern API development using Microsoft's streamlined Minimal API architecture.In this hands-on, project-driven course, you will build a fully functional, production-ready API used to manage fictional research sites, artifacts, catalog records, media files, and user accounts inside the Aeon Registry system.Whether you are new to .NET or transitioning from MVC controllers, this course guides you step-by-step through designing, structuring, building, documenting, and deploying a real application following industry best practices.Why This Course Stands OutThis is not a basic demo API. You will architect a complete multi-layered system with:Authentication and role-based authorizationIdentity API endpoints (with custom overrides)Fully designed Site and Artifact management systemsPublic and private endpoint architectureMedia upload, validation, and binary image deliveryPostgreSQL integration through Entity Framework CoreProduction-level error handling and filtersBranded Swagger documentationDeployment to Railway using DockerStatic file hosting, maps, and a homepageEvery feature is taught through real implementation, not theory.What You Will LearnBy the end of this course, you'll be able to build professional-grade Minimal API applications, including:Minimal API ArchitectureOrganize projects using entities, DTOs, services, filters, and endpoint groupsImplement consistent CRUD endpoint patternsApply projection and mapping techniques for response modelsAuthentication and AuthorizationAdd ASP.NET Identity through the minimal API approachMap built-in Identity endpoints (register, login, password reset, etc.)Configure custom policies and role-based accessOverride the default registration endpoint for admin-controlled onboardingGenerate and send password reset links to new usersReal Application FeaturesBuild dozens of endpoints across Sites, Artifacts, and MediaFilesReturn public vs. private versions of the same dataDesign nested endpoints such as retrieving artifacts by siteSeparate concerns across service and routing layersDatabase Integration with PostgreSQLConfigure EF Core DbContext for PostgreSQLUnderstand navigation properties and one-to-many relationshipsUse asynchronous queries, projections, and eager loadingSecure Media UploadsProcess multipart file uploadsValidate MIME types, file extensions, and magic bytesEnforce File Size limitsServe binary images with caching headersProduction-Grade API PracticesImplement a centralized exception handling filterAdd custom Swagger branding and documentationOrganize endpoint groups with shared metadataHost static files and build a lightweight front-end entry pageCloud Deployment and DevOpsContainerize your API with DockerDeploy to Railway using GitHub integrationHandle Railway's DATABASE_URL using dynamic connection-string generationPublish Swagger in production environmentsConfigure environment variables and static hostingWhat You Will BuildThroughout the course, you will create the complete Aeon Registry Minimal API, a real-world backend designed to manage research and artifact cataloging.Site Management APICreate, update, delete, and retrieve research sitesReturn both public summaries and private research narrativesBuild nested routes for artifacts belonging to a siteArtifact Cataloging SystemCreate and manage artifact recordsSupport relationships between artifacts, sites, media files, and catalog notesProvide public and private endpoints with different response modelsMedia Upload and Retrieval SystemUpload and store image filesValidate image content, size, and typeServe binary image data publiclyManage primary image selection for artifactsIdentity and User ManagementImplement ASP.NET Core Identity using Minimal APIsAdd custom registration logic for administratorsAssign roles such as "Researcher"Send password-setup links via emailCloud Deployment with Docker and RailwayBuild and deploy a Dockerized applicationAdd and configure a PostgreSQL database in RailwayManage environment variables and automatic connection stringsHost static files and map viewersSet up CI/CD with GitHubTopics Covered in DepthMinimal API ConceptsEndpoint groupsHandler designTyped resultsException filtersService abstractionIdentity and SecurityJWT authenticationRole-based policiesCustom onboarding flowsEntity Framework CoreEntities, foreign keys, navigation propertiesEager loading with IncludeProjections with LINQAsynchronous database operationsMedia HandlingSafe multipart file processingHeader-byte inspectionFile Size and type validationBinary response formattingCloud DeploymentDockerfile configurationRailway hostingProduction SwaggerStatic file hostingWho This Course Is ForDevelopers learning Minimal APIs for the first timeASP.NET MVC developers wanting to adopt modern patternsStudents building their first complete backend applicationEngineers preparing for backend or full-stack rolesAnyone who wants hands-on experience deploying a real .NET API to the cloudYour Final ProjectUpon completing the course, you will have a fully deployed, production-ready API featuring:A complete authentication and authorization systemPublic and private data separationA secure media upload system with validationEnd-to-end CRUD operations for multiple resourcesPostgreSQL integration through EF CoreA custom-branded Swagger dashboardA deployed Railway applicationA static homepage and interactive map viewerCI/CD automation through GitHubThis is a portfolio-quality project demonstrating practical, modern backend development skills.
