I have been trying for two days to get the SQL server 2012 to run with metro style when I finally discovered that metro style doesn't support this database client. then I switched over to sqlite3 database. I have created the classes for each database.But when i try to create the DB with this code

private async void CreateDatabase()
    {
        SQLiteAsyncConnection conn = new SQLiteAsyncConnection("people");
        await conn.CreateTableAsync<users>();  
        await conn.CreateTableAsync<groups>();
    }

the following errors occur

An exception of type 'System.BadImageFormatException' occurred in EduHaptics.exe but was not handled in user code

Additional information: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) in the line

SQLite3.SetDirectory(/*temp directory type*/2, Windows.Storage.ApplicationData.Current.TemporaryFolder.Path);

and same error at line

await conn.CreateTableAsync<users>(); 

tried to insert the path manually after i acquired it, but the same problems occur. I also navigated to that location it does exist but it is an empty folder. I have a clue that it might be not reading the path well because of the String itself but i don't know what to do!! any help please I am programming in visual studio 2013 64-bit environment and i acquired the sqlite-winrt81-3080401 version.
