# BackgroundBuilder
An MVVM WPF application (.NET 6) providing an Excel-like editor for the `contatos` table in PostgreSQL.

## Prerequisites
## 📝 Project description
- .NET 6 SDK
- PostgreSQL database with table:
> 🖥️ An MVVM WPF application (.NET 8) providing an Excel-like editor for the `contatos` table in PostgreSQL
```sql
CREATE TABLE public.contatos (
ramal text PRIMARY KEY NOT NULL,
nome text NOT NULL,
email text,
area text,
aniversario date,
"isComando" boolean NOT NULL
);
```
## Setup
1. Edit appsettings.json, set your ConnectionStrings:ContatosDb.
2. In a terminal:
```bash
dotnet restore
dotnet build
dotnet run --project BackgroundBuilder.csproj
```
3. The main window will appear; on load it fetches and displays all contatos.
## Architecture
- MVVM with MVVM with ObservableObject, RelayCommand.
- DI via Microsoft.Extensions.Hosting.
- Repositories (PostgresContatoRepository) handle all DB I/O with Dapper.
- Services (DatabaseService) manage the Npgsql connection.
- ViewModels free of data-access logic: only orchestration.
---
### New Background & Export Features
## 📑 Prerequisites
- **Select Background…**
- [![.NET](https://img.shields.io/badge/.NET_8.0-blueviolet?logo=dotnet&logoColor=white)](https://dotnet.microsoft.com/)
- [![PostgreSQL](https://img.shields.io/badge/PostgreSQL-4169E1?logo=postgresql&logoColor=white)](https://www.postgresql.org/) **database** with table:
```sql
CREATE TABLE public.contatos (
ramal text PRIMARY KEY NOT NULL,
nome text NOT NULL,
email text,
area text,
aniversario date,
"isComando" boolean NOT NULL
);
```
---
## 🔧 Setup
1. ✏️ Edit `appsettings.json`, set your `ConnectionStrings:ContatosDb`.
2. 🖥️ In a terminal:
```bash
dotnet restore
dotnet build
dotnet run --project BackgroundBuilder.csproj
```
3. 🪟 The main window will appear; on load it fetches and displays all contatos.
---
## 🏗️ Architecture
- 🏛️ **MVVM** with `ObservableObject`, `RelayCommand`
- 🧩 **DI** via `Microsoft.Extensions.Hosting`
- 💾 **Repositories** (`PostgresContatoRepository`) handle all DB I/O with Dapper
- 🔌 **Services** (`DatabaseService`) manage the Npgsql connection
- 🧠 **ViewModels** free of data-access logic: only orchestration
---
## 🚀 Releases
### 📆 21/05/2025: 🆕 Background & Export Features
- 🎨 **Select Background…**
Opens a file picker—choose any image (PNG, JPG, BMP). That image becomes your canvas.
- **Create Image…**
- 🖼️ **Create Image…**
Saves the current DataGrid overlaid on the background as a single PNG.
Uses WPF’s `RenderTargetBitmap` and `PngBitmapEncoder` under the hood.

## Prerequisites
## 📝 Project description
- .NET 6 SDK
- PostgreSQL database with table:
> 🖥️ An MVVM WPF application (.NET 8) providing an Excel-like editor for the `contatos` table in PostgreSQL
```sql
CREATE TABLE public.contatos (
ramal text PRIMARY KEY NOT NULL,
nome text NOT NULL,
email text,
area text,
aniversario date,
"isComando" boolean NOT NULL
);
```
## Setup
1. Edit appsettings.json, set your ConnectionStrings:ContatosDb.
2. In a terminal:
```bash
dotnet restore
dotnet build
dotnet run --project BackgroundBuilder.csproj
```
3. The main window will appear; on load it fetches and displays all contatos.
## Architecture
- MVVM with MVVM with ObservableObject, RelayCommand.
- DI via Microsoft.Extensions.Hosting.
- Repositories (PostgresContatoRepository) handle all DB I/O with Dapper.
- Services (DatabaseService) manage the Npgsql connection.
- ViewModels free of data-access logic: only orchestration.
