1969294 - Error: "Failed to find or load the registered .Net Framework Data Provider" or "Unable to find the requested .NET framework data provider. It may not be installed."

• The System.Data.Common.DBProviderFactories object allows Microsoft .NET programmers to program against different databases without requiring an explicit link reference to an ADO.NET data provider. This allows for .NET developers to develop a "common code base" for different databases and request different database ADO.NET data providers at runtime. When working with the SQL Anywhere ADO.NET Provider and the DBProviderFactories class, it is possible to see the exception:

  System.ArgumentException - "Unable to find the requested .NET framework data provider. It may not be installed."

    or

  System.ArgumentException - "Failed to find or load the registered .Net Framework Data Provider"

after deploying a .NET application to an environment where the SQL Anywhere client software was also deployed.

• The DBProviderFactories class can be referenced either explicitly in .NET code, or implicitly when using ASP.NET and a web.config file with <connectionStrings> and <add ... providerName=""> XML tags.
