Prerequisites

The Dyalog version 20.0 .NET Framework interface requires version 4.0 or greater of Microsoft .NET Framework. It does not operate with earlier versions of the .NET Framework. In addition:

• .NET Framework version 4.5 is needed for full Data Binding support (including support for the INotifyCollectionChanged interface, which is used by Dyalog to notify a data consumer when the contents of a variable, that is data bound as a list of items, changes).
• .NET Framework version 4.6 is needed to run the Syncfusion libraries supplied with Dyalog version 20.0.
• IIS needs to be installed before installing Dyalog APL in order to access the examples in the Samples/asp.net sub-directory – if IIS and ASP.NET are not present, the asp.net sub-directory will not be installed during the Dyalog installation.

Note that .NET Framework is specific to Microsoft Windows; the cross-platform .NET is also supported (see below).
