Microsoft's Azure Data Lake is now generally available, but what does it do, and how does it work? Here's a tour around the service's tooling and capabilities, to help you understand it and get productive with it, quickly.
Doing Azure Data Lake work in Visual Studio is about more than using a desktop app. That's because U-SQL queries can call functions written in C#, either in code-behind files or in separate .NET assembly projects.
The source code for a C# function called get_mentions is shown here. Look at the Solution Explorer window at the upper-right and you'll see that the class file containing this code is in its own C# project, separate from the Azure Data Lake project, but in the same Visual Studio solution.
C# expressions can also be used inline, in U-SQL scripts. This includes scripts built in the Azure portal. The C# code-behind and assembly techniques require Visual Studio though.
