 数据库上下文

public class SQLiteContext : DbContext
{
    public DbSet<Mod1> Mod1s { set; get; }
    public DbSet<Mod2> Mod2s { set; get; }
    ......
}

EF暖机（可以写在初始化的函数中，用于解决首次查询慢的问题）

// EF暖机（SQLite）
using (SQLiteContext dbContext = new SQLiteContext())
{
    var objectContext = ((IObjectContextAdapter)dbContext).ObjectContext;
    var mappingCollection = (StorageMappingItemCollection)objectContext.MetadataWorkspace.GetItemCollection(DataSpace.CSSpace);
    mappingCollection.GenerateViews(new List<EdmSchemaError>());
}
