Telerik Reporting Deployment System.IO.FileNotFoundException: Could not load file or assembly 'Telerik.OpenAccess, Version=2015.1.225.1, Culture=neutral, PublicKeyToken=7ce17eeaf1d59342' or one of its dependencies. The system cannot find the file specified.
The issue is related to a reference to Telerik.Reporting.Cache.Database.dll or a copy of Telerik.Reporting.Cache.Database.dll in the Bin folder of the deployed application. This assembly is related to the database cache of old viewers, including the obsolete ASP.NET WebForms ReportViewer, but not the Reporting REST service and HTML5 Viewer. The Reporting REST service uses different cache mechanism -REST Service Storage.
The solution is to remove Telerik.Reporting.Cache.Database.dll from the project. Or if you use an old viewer and database cache - Configuring the Database Cache Provider, where you may need binding redirects depending on the used Telerik Data Access version.
The used Telerik Data Access version is specified in the dependencies list in eachrelease notes and the corresponding Upgrade Path help article.
