Unable to open an entity framework model in LinqSample


I'm trying to open SampleModel.edmx that comes with LinqSample project, which in turns comes as a sample with SQLA 16. I receive the following message: "Unable to cast object of type 'iAnywhere.Data.SQLAnywhere.SAProviderServices' to type 'System.Data.Common.DBProviderServices'". The problem exists in both Visual Studio 2013 and 2015, and after I followed all installation instructions. Any advice is very much welcome.

    I have tested with Visual Studio Professional 2013 update 5 and SQL Anywhere 16 and I can open LinqSample SampleModel.edmx on Windows 8.1.

    Did you have to convert the project to open it in VS 2013? Have you selected .NET Framework 4.5?

    • I would start making sure that you are running SQL Anywhere or above. EF 6 support has been introduced since then. Then open the readme_EBF.HTML file that is in C:\Program Files\SQL Anywhere 16 (by default) and search for Engineering Case # 768717 and confirm you have followed the instructions please.
