如果我的连接字符串包含max database size关键字，为什么SQL Server Compact Edition无法打开现有的SDF文件？

Question

I keep seeing this exception:

ex = {"Keyword not supported: 'max database size'."}

When I try running the following code (exception is thrown on the LINQ query line):

LogContext l = new LogContext(connectionString);
var v = from log in l.Logs select log;
count += v.Count();

The LogContext class looks like this:

public class LogContext : DbContext
{
    public LogContext()
        : base()
    {
    }
    public LogContext(string connectionString)
        : base(connectionString)
    {
    }
    public DbSet<LogRecord> Logs { get; set; }
}

My connection string contains the Max Database Size property. Is there a reason why its throwing this exception? Does SQL Server Compact Edition use the Max Database Size property only once for creating the database and stores this information in the local file or something, such that I can't connect to this file when I specify this property thereafter? Because this all works when I create new databases.

Setting the DefaultConnectionFactory seemed to work for me:

Database.DefaultConnectionFactory = new SqlCeConnectionFactory("System.Data.SqlServerCe.4.0");
