<commit_before>##Breaking API changes in 3.0.0! 

Use 
`new SendGridMessage()` instead of `SendGrid.GetInstance()` 

and `new Web()` instead of `Web.GetInstance()`

#Requirements

This library requires .NET 4.0 and above.

#Installation

To use SendGrid in your C# project, you can either <a href="https://github.com/sendgrid/sendgrid-csharp.git">download the SendGrid C# .NET libraries directly from our Github repository</a> or, if you have the NuGet package manager installed, you can grab them automatically.

```
PM> Install-Package SendGrid 
```

Once you have the SendGrid libraries properly referenced in your project, you can include calls to them in your code. 
For a sample implementation, check the [Example](https://github.com/sendgrid/sendgrid-csharp/tree/master/SendGrid/Example) folder.

Add the following namespaces to use the library:
```csharp
using System;
using System.Net;
using System.Net.Mail;
using SendGrid;
```

#How to: Create an email

Use the static **SendGrid.GetInstance** method to create an email message that is of type **SendGrid**. Once the message is created, you can use **SendGrid** properties and methods to set values including the email sender, the email recipient, and the subject and body of the email.
