I have built a wpf application that is using EF and SQLCE4.

Everything works fine on my local dev machine however when I package it up and install on a test machine I keep getting this error

Inner Expection System.ArgumentException: Unable to find the requested .Net Framework Data Provider. It may not be installed.
at System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName)
at System.Data.EntityClient.EntityConnection.GetFactory(String providerString)

I have installed the SQLCE4 application and both .net4 client & extended frameworks.

Has anyone run into this problem before?

    You can use NuGet package manager 1.5 (for VS 2010 SP1) and download the SQL CE 4 package first.

    And then add the package to you project, and rebuild it.

    For info about SQL Server CE 4’s Nuget:
