IBM i .NET Data Provider And .NET Core

Product Documentation


Abstract

The IBM i .NET data provider (IBM.Data.DB2.iSeries) is not supported for use with .NET Core

Content

Microsoft states: ".NET Framework 4.8 is the last version of .NET Framework." In 2016, Microsoft created a new version of .NET called .NET Core (now called just .NET) that is a platform-independent implementation successor to the .NET Framework. Because it is platform-independent, many Windows-specific APIs that were provided by .NET Framework are not available in .NET Core. Because the IBM i .NET data provider depends on some of those Windows-specific APIs, it does not work in .NET Core, and an attempt to use this .NET provider results in a failure. The exception received doesn't make clear what the cause of that failure is. The following is the failure I get from a simple .NET Core application that loads and makes a connection with the IBM i .NET data provider:

System.TypeInitializationException: The type initializer for 'IBM.Data.DB2.iSeries.iDB2Trace' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Security.Permissions, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

Alternatives:
  • Microsoft provides an ODBC bridge provider System.Data.Odbc, available in NuGet, which can be used with the IBM i Access ODBC driver
  • The .NET provider from the Db2 Connect family can be used with .NET Core. Contact your business partner or IBM sales representative for details on these products
  • While not a standard .NET data provider, the open source IbmiXmlserviceStd package provides database access (along with the ability to call programs, CL commands, and more) in .NET through XMLSERVICE
