🚀 Getting Started

Prerequisites

• .NET 9.0 SDK
• JetBrains Rider or Visual Studio 2022

Installation and Running

1. Clone the repository

   git clone https://github.com/m1lean/ProjectManagementSystem.git
   cd ProjectManagementSystem

2. Restore dependencies

   dotnet restore

3. Run the application

   dotnet run

4. Open in browser

   http://localhost:5000
   

Running in JetBrains Rider

1. Open the project in Rider
2. Build the project (Ctrl+Shift+B)
3. Run the project (Ctrl+F5)

📊 Data Model

Core Entities

• Project - Project with name, description, and status
• ProjectTask - Task linked to a project and assigned to a user
• User - System user
• ProjectUser - Junction entity for project members (many-to-many)

Relationships

• Project → Tasks (one-to-many)
• Project ↔ Members (many-to-many through ProjectUser)
• Task → User (many-to-one for assignment)

🌐 API Endpoints

Method	Endpoint	Description
GET	/Projects	List all projects
GET	/Projects?status=Open	Filter by status
GET	/Projects/Details/{id}	Project details
GET	/Tasks?projectId={id}	Project tasks
GET	/Users	List users
GET	/Users/Participants?projectId={id}	Project members

🧪 Test Data

The application automatically creates test data on startup:

• Sample users
• Demo project
• Related tasks and members

🔧 Configuration

Database Switch

To use a real database (e.g., SQL Server), modify in Program.cs:

// Replace
builder.Services.AddDbContext<ApplicationDbContext>(options =>
    options.UseInMemoryDatabase("ProjectManagementDb"));

// With
builder.Services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(connectionString));

🚧 Current Limitations

• Database: Uses in-memory database, data is not persisted after restart
• Authentication: No authorization system
• Validation: Basic server-side validation only
• UI: Minimal interface without JavaScript

🎯 Roadmap

• Migrate to real database (SQL Server/PostgreSQL)
• Add authentication system (ASP.NET Core Identity)
• Improve UI with Bootstrap/modern CSS frameworks
• Add REST API endpoints
• Implement real-time notifications (SignalR)
• Add file attachments to tasks
• Role-based access control
• Mobile responsiveness
• Unit and integration tests
