| I'm very new to ECO and CapableObjects and I'm having some issues with persistent storage using MS-SQL. I can create a new model with two single classes each with two string attributes, I save the model, I then generate the code and compile, so far everything is good. I then open the XXXPMP file, make sure that the sqlConnection object has a valid ConnectionString, I then validate the model and generate the model and it seems to work. The problem is that when I explore the db, it has only created a "class1" table. If I delete all classes using CTRL+Delete, generate the code, compile, validate and generate schema everything seems to work, but once again if I explore the db, I have a table called class1. I can delete the table using sql, generate the schema (without any objects) and the class1 table is back in the db. I have read "Making the EcoSpace persistean.pdf".

| Hi You need to compile your model dll before gerenating the schema from the persistence mapper provider. Nick

Hi Terry
Sometimes Visual Studio caches the model DLL (it happens only very rarely for me) so if you ever see something like this occur trying restarting VS and seeing if that resolves it.
