MyStudyTime

A modern study management application built with WPF and .NET 8 to help you organize your subjects, notes, and flashcards.

Features

• Subject Management: Create and organize different study subjects
• Note Taking: Add and manage notes for each subject
• Flashcards: Create and review flashcards with difficulty levels
• Search Functionality: Search across all your notes and flashcards
• Data Persistence: Dual-backend support:
  • Database: SQL Server with Entity Framework 6
  • Fallback: XML-based storage when database is unavailable

Architecture

• UI Framework: WPF (Windows Presentation Foundation)
• Framework: .NET 8 (modern, long-term support)
• ORM: Entity Framework 6 with SQL Server
• Pattern: MVVM (Model-View-ViewModel)

Prerequisites

• .NET 8 SDK or later (download from dotnet.microsoft.com)
• Visual Studio Code or any .NET IDE
• SQL Server Express (for database persistence) - optional, falls back to XML storage

Getting Started

Build

# Build the project
dotnet build src/MyStudyTime/MyStudyTime.csproj

# Or use the VSCode build task
Ctrl+Shift+B

Run

# Run the application
dotnet run --project src/MyStudyTime/MyStudyTime.csproj

# Or use the VSCode run task
Ctrl+Shift+B > select "run"

Debug

• Set breakpoints in VSCode
• Press F5 to start debugging (uses launch.json configuration)
• The app will launch with debugger attached

Data Persistence

Database (Recommended)

By default, the application attempts to connect to SQL Server Express:

• Connection String: Server=.\SQLEXPRESS;Database=StudyTime;Integrated Security=true;
• Modify in appsettings.json if needed

Fallback Storage

If SQL Server is unavailable, data automatically persists to XML files in:

%APPDATA%\MyStudyTime\
├── subjects.xml
├── flashcards.xml
└── studygoals.xml

Development

Key Technologies

• WPF: Modern desktop UI with data binding
• .NET 8: Current LTS release with performance improvements
• Entity Framework 6: ORM for database operations
• MVVM Pattern: Separation of concerns for maintainability

Project File Format

The project uses SDK-style .csproj format (modern, clean, and VSCode-friendly):

• No packages.config — uses PackageReference in .csproj
• Automatic resource discovery
• .NET 8 with Windows Desktop support

Troubleshooting

Database Connection Fails

If you see warnings about database unavailability:

1. Ensure SQL Server Express is installed and running
2. Check the connection string in appsettings.json
3. App will automatically fall back to XML storage

Build Issues

# Clean and rebuild
dotnet clean src/MyStudyTime/MyStudyTime.csproj
dotnet build src/MyStudyTime/MyStudyTime.csproj

Restore Dependencies

dotnet restore src/MyStudyTime/MyStudyTime.csproj
