Azure Core Expressions DataFactory shared client library for .NET

Azure.Core.Expressions.DataFactory provides shared classes that represent Expression.

Getting started

Typically, you will not need to install Azure.Core.Expressions.DataFActory; it will be installed for you when you install one of the client libraries using it. In case you want to install it explicitly (to implement your own client library, for example), you can find the NuGet package.

Key concepts

In the datafactory API many of the properties have the ability to either be a constant value or an expression which will be evaluated at runtime. The structure of an expression is different than a constant value for example the FolderPath property of an AzureBlobDataset can either be a "string (or Expression with resultType string)".

Json representation

"folderPath": "foo/bar"
"folderpath": {
  "type": "Expression",
  "value": "foo/bar-@{pipeline().TriggerTime}"

In this example when the pipeline is run in the first case the folder is always foo/bar, but in the second case the service will append the time the pipeline kicked off to the folder name.


The DataFactoryExpression<T> class allows us to model the literal value expected by this property using strongly typed practices. If the expression should evaluate to an int then a literal value that is assigned to the same property must also be an int.

With the FolderPath example above we could set the property using either case below.

  azureBlobDataset.FolderPath = "foo/bar";
  azureBlobDataset.FolderPath = DataFactoryExpression<string>.FromExpression("foo/bar-@{pipeline().TriggerTime}");

In each case the library will be able to serialize and deserialize both scenarios appropriately allowing you to seemlessly use either according to your applications needs.


Three main ways of troubleshooting failures are inspecting exceptions, enabling logging, and distributed tracing
