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?
解决方案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.
