Where to put embedded database file for clickonce deployment

问题

Using a SQLite embedded database. I am using Entity Framework 6. I have the database in the bin folder when I am testing. While testing EF connects fine with the following connection string:

    public Entities() : 
            base(@"metadata=DataModel1.csdl|DataModel1.ssdl|DataModel1.msl;provider=Devart.Data.SQLite;provider connection string=""Data Source=database.db;FailIfMissing=False""", "Entities")
    {
        this.ContextOptions.LazyLoadingEnabled = true;
        OnContextCreated();
    }

When I deploy the app using ClickOnce the app does not connect to the database. I have checked to see that the database file is in the same folder with the exe file and all the dll's. It is. The path is:

C:\Users\erics\AppData\Local\Apps\2.0\3C5PX0RL.NTX\CEV4Q75L.OMO\ther..tion_680a5823070fb75b_0001.0000_db2ce9b27afbcd77

Do I need to control the location of the database.db file? If so, how do I do that with ClickOnce?

Do I need something different for the path to the database file in the connection string?

Exact Error:
