# Notepad.Extensions.Logging
[![NuGet](https://img.shields.io/nuget/v/Notepad.Extensions.Logging)](https://www.nuget.org/packages/Notepad.Extensions.Logging/)
This is a library for .NET / .NET Core to log your program's output to a handy Notepad window!
## Installation
To use:
1. Add a package reference to `Notepad.Extensions.Logging`.
2. In `Startup.cs`, call `AddNotepad()`, like so:
```csharp
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
// ...
services.AddLogging(lb => lb.AddNotepad()); // This is where the magic happens
}
```
3. Open a new Notepad window.
4. Run your application.
