The Force.com Toolkit for .NET provides an easy way for .NET developers to interact with the Force.com REST API using a native libraries. This toolkit is built using the Async/Await pattern for asynchronous development and .NET portable class libraries, making it easy to target multiple Microsoft platforms, including .NET 4/4.5, Windows Phone 8, Windows 8/8.1, and Silverlight 5.

You can try the library immmediately by installing this NuGet package.

Install-Package DeveloperForce.Force

If you want to use the most recent DevTest NuGet packages you can grab the packages built during the CI build. All you need to do is setup Visual Studio to pull from the build servers NuGet feed:

1. In Visual Studios select Tools -> Library Package Manager -> Package Manager Settings. Choose Package Sources.
2. Click + to add a new source.
3. Change the Name to "Salesforce Toolkit for .NET (DevTest)".
4. Change the Source to http://dfbuild.cloudapp.net/guestAuth/app/nuget/v1/FeedService.svc/.

Now you can choose to install the latest NuGet from this DevTest feed.

The toolkit includes the following sample applications.

You can find this sample here: https://github.com/developerforce/Force.com-Toolkit-for-NET/tree/master/samples/WebServerOAuthFlow

This sample shows how you can use the Web Server OAuth Authentication Flow to authorize a user and query the Force.com API. This sample uses MVC 5 and WebAPIs to demonstrate how you can retrieve a user access token and make an AJAX call to your API to retrieve data from Force.com and bind to your page using Knockout.js.

You can see this demo live here: https://sfdcauth.cloudapp.net/

You can find this sample here: https://github.com/developerforce/Force.com-Toolkit-for-NET/tree/master/samples/SimpleConsole

This sample shows how to write a console application that leverages the async/await paradigm of .NET 4.5 and uses the toolkit to log in to and communicate with a Salesforce organization. Useful for quick POC applications and scheduled jobs.

Currently the following operations are supported.

To access the Force.com APIs you must have a valid Access Token. Currently there are two ways to generate an Access Token: the Username-Password Authentication Flow and the Web Server Authentication Flow

The Username-Password Authentication Flow is a straightforward way to get an access token. Simply provide your consumer key, consumer secret, username, and password.

var auth = new AuthenticationClient();

await auth.UsernamePasswordAsync("YOURCONSUMERKEY", "YOURCONSUMERSECRET", "YOURUSERNAME", "YOURPASSWORD");

The Web-Server Authentication Flow requires a few additional steps but has the advantage of allowing you to authenticate your users and let them interact with the Force.com using their own access token.

First, you need to authetnicate your user. You can do this by creating a URL that directs the user to the Salesforce authentication service. You'll pass along some key information, including your consumer key (which identifies your Connected App) and a callback URL to your service.

var url =
    Common.FormatAuthUrl(
        "https://login.salesforce.com/services/oauth2/authorize", // if using test org then replace login with text
        ResponseTypes.Code,
        "YOURCONSUMERKEY",
        HttpUtility.UrlEncode("YOURCALLBACKURL"));

After the user logs in you'll need to handle the callback and retrieve the code that is returned. Using this code, you can then request an access token.

await auth.WebServerAsync("YOURCONSUMERKEY", "YOURCONSUMERSECRET", "YOURCALLBACKURL", code);

You can see a demonstration of this in the following sample application: https://github.com/developerforce/Force.com-Toolkit-for-NET/tree/master/samples/WebServerOAuthFlow

After this completes successfully you will receive a valid Access Token and Instance URL. The Instance URL returned identifies the web service URL you'll use to call the Force.com REST APIs, passing in the Access Token. Additionally, the authentication client will return the API version number, which is used to construct a valid HTTP request.

Using this information, we can now construct our Force.com client.

var instanceUrl = auth.InstanceUrl;
var accessToken = auth.AccessToken;
var apiVersion = auth.ApiVersion;

var client = new ForceClient(instanceUrl, accessToken, apiVersion);
```

### Sample Code

Below you'll find a few examples that show how to use the toolkit.

#### Create

You can create with the following code:

```
public class Account
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
}

...

var account = new Account() { Name = "New Account", Description = "New Account Description" };
var id = await client.CreateAsync("Account", account);
```

You can also create with a non-strongly typed object:

```
var client = new ForceClient(_consumerKey, _consumerSecret, _username, _password);
var account = new { Name = "New Name", Description = "New Description" };
var id = await client.CreateAsync("Account", account);
```

#### Update

You can update an object:

```
var account = new Account() { Name = "New Name", Description = "New Description" };
var id = await client.CreateAsync("Account", account);

account.Name = "New Name 2";

var success = await client.UpdateAsync("Account", id, account);
```

#### Delete

You can delete an object:

```
var account = new Account() { Name = "New Name", Description = "New Description" };
var id = await client.Create("Account", account);
var success = await client.DeleteAsync("Account", id)
```

#### Query

You can query for objects:


```
public class Account
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
}

...

var accounts = await client.QueryAsync<Account>("SELECT id, name, description FROM Account");
```
