We recently posted about trying to release WCF Data Services more frequently, and some of the changes we’re making. In this post, we’ll take a slightly deeper look at NuGet,bin deploy, and where WCF Data Services is headed.
If you’re already familiar with NuGet, you probably understand its value proposition and can skip ahead to bin deploying applications. If you haven’t used NuGet before, this section will provide you with a quick introduction. The NuGet site has a great documentation section that provides significantly more detail.
What is NuGet?
Languages such as Ruby and Python have package management systems that make it trivial to take a dependency on a centrally published package. NuGet provides similar functionality for .NET. With a few clicks or a simple command a developer can take a dependency on Microsoft.Data.Services.Client, the assembly that provides WCF Data Services client functionality. Taking a dependency on that package adds three other packages to your project: Microsoft.Data.OData, Microsoft.Data.Edm and System.Spatial.
Getting a specific version of WCF Data Services is also very easy: issuing the command Install-Package Microsoft.Data.Services.Client –Version 5.0.1 will install version 5.0.1 of the client, even if there is a more recent version of the client published. (Issuing the command Install-Package Microsoft.Data.Services.Client or installing the package with the explorer will always get the most recent version of the client.)
Install-Package Microsoft.Data.Services.Client –Version 5.0.1

Updating Packages with NuGet
In addition to the simple installation process, NuGet makes it easy to update packages.

Simplified Dependency Management
In summary, NuGet greatly simplifies the process of locating, downloading, and adding references to the most recent version of WCF Data Services. Developers no longer need to search the Download Center for a version of WCF Data Services, sort by date, download and install an MSI, manually copy the DLLs and add a reference to them, etc. With NuGet developers simply use the Manage NuGet Packages dialog or the Package Manager Console to easily take a dependency on WCF Data Services.
Bin deployment is a term commonly used for a deployment process wherein the contents of the bin folder (potentially with a few other files) are copied to a server using a very simple file copy or similar process. In other words, bin deploy scenarios do not require an MSI to be run on the server that will host the application. This is especially key in scenarios where the server is not controlled by the developer (e.g., Web hosting). However, bin deploy is also beneficial in many other scenarios. Some of the benefits of bin deploy are as follows:
Bin deployment is also a natural companion for NuGet, semantic versioning, and our amended EULA for the imminent 5.0.1 version of WCF Data Services, which will include a redistribution clause.
Down the road, we will be taking a much deeper dependency on NuGet – we are currently revamping our tooling to install NuGet packages when you add a WCF Data Service or a reference to an OData service to your application.
