Development of Telerik Data Access product is now driven by our internal company needs and is happening on irregular basis.
We are no longer offering customer support package for the product. You are welcome to post in our community forums, but we do not guarantee any response.
Support for Visual Studio 2017 should come naturally (but we have not tested it) with our NuGet packages. You can already test it using the latest release candidate and the latest existing Telerik Data Access release.
The product already supports Microsoft SQL Server CE 4.0 (and its successor SQL Server Express LocalDb
We have no plans for supporting .Net Core and respectively ASP.NET Core frameworks. ASP.NET Core targeting the full .Net Framework may work.
In general my personal recommendation is to avoid starting new projects with Telerik Data Access.
