You can use SDK directly in your project via the source code or get a NuGet Package. From the Package Manager:

PM> Install-Package Aspose.Email-Cloud

Using .NET CLI:

dotnet add package Aspose.Email-Cloud

Or as a Package reference:

<PackageReference Include="Aspose.Email-Cloud"/>

See more details about SDK installation in this tutorial: SDK setup.

Usage examples

To use the API, you should create an EmailCloud object:

using Aspose.Email.Cloud.Sdk.Api; //EmailApi class is here
using Aspose.Email.Cloud.Sdk.Model; //REST API models are here

var clientSecret = "Your client secret";
var clientId = "Your client id";
var api = new EmailCloud(clientSecret, clientId);

var result = await api.Calendar.GetAsync(new CalendarGetRequest(calendarFile, folder, StorageName));

Business cards recognition API

Use EmailCloud.Ai.Bcr.Parse method to parse business card image to VCard DTO:

var imageFilePath = "path/to/image/to/parse.png";
using (var file = File.OpenRead(imageFilePath))
    var result = await api.Ai.Bcr.ParseAsync(
        new AiBcrParseRequest
            File = file,
            IsSingle = true
    ContactDto contact = result.Value.First();
    Assert.AreEqual("Parsed Display Name", contact.DisplayName);
