CalDAV for .NET

A .NET Standard 2.0 library to work with CalDAV servers.

Features

• Connection Management: Connect to CalDAV by respecting redirects and .well-known/caldav information.
• Principal Discovery: Discover the principal URL for a user.
• Calendar Management: Create, list and delete calendars.
• Event Management: Create, list, update and delete events.
• iCal Support: Support for iCalendar format (RFC 5545) for event data provided by ical.net.

Usage

using AMWD.Protocols.CalDAV;

using var client = new CalDavClient("https://your.caldav.host", "username", "P@ssw0rd!");
bool isInitialized = await client.InitializeAsync();
if (!isInitialized)
{
	Console.WriteLine("Failed to initialize CalDAV client.");
	return;
}

var calendars = await client.GetCalendarsAsync();
foreach (var calendar in calendars)
{
	Console.WriteLine($"Calendar: {calendar.DisplayName} ({calendar.Url})");
}

Supported CalDAV Servers

The support might be limited as some providers do not allow creating/deleting new calendars.
Also the authentication is limited to Basic Authentication.
