The SQL Anywhere database contains Tables, Views and Stored procedures. Creating a new Entity Framework Data Model (Add, new item, ADO.NET Entity Data Model, generated model from the database) the list of possible database objects contains only the Tables and Views. No Stored procedures can be selected in the Entity Framework import dialog, there aren't there!!
In the Visual Studio 2010 Server Explorer all Tables, Views and Stored procedures(!!) are shown. So it should work for EF as well. Both connections are using the same Data source ".Net Framework Data Provider for SQL Anywhere 12", Server name, Database name etc.
Does anyone have the same problem or a clue? I use SQL Anywhere developer edition version 220.127.116.1169
Note: I tried the same with SQL Server..... no problem (but thats not the production database).
