CodeDom Types Supported by Windows Workflow Foundation

Windows Workflow Foundation uses the types that are available in System.CodeDom, which is part of the .NET Framework. You can use these types to author your conditions. Some types are supported in conditions, some in rule actions, and some in both.

Note

System.CodeDom does not support unary operators, nor does it support value inequality, such as a != b. You can express value inequality indirectly by using an expression such as (a == b) == false.

The following tables show the supported System.CodeDom types.
