C# 基于实体框架6.1和SQLServerCE4异常的通用存储库。“无效操作例外”

我正试图创建一个基于EntityFramework6.1和SQLServerCE4的通用存储库，但有一个例外

“System.InvalidOperationException”类型的第一次意外异常 发生在EntityFramework.dll中 附加信息：实体类型TestClass不是 当前上下文的模型

这是我存储库的代码，我还附加了一个测试项目

public class Repository<T> : IRepository<T> where T : class
{
    private readonly DataContext context;

    private DbSet<T> dbSet;

    public Repository(DataContext dataContext)
    {
        this.context = dataContext;
        this.dbSet = this.context.Set<T>();
    }

    public IQueryable<T> GetAll()
    {
        throw new NotImplementedException();
    }

    public IQueryable<T> FindAllBy(Expression<Func<T, bool>> predicate)
    {
        throw new NotImplementedException();
    }

    public T FindFirstBy(Expression<Func<T, bool>> predicate)
    {
        throw new NotImplementedException();
    }

    public void Add(T entity)
    {
        this.dbSet.Add(entity);
        this.context.SaveChanges();
    }

    public void Delete(T entity)
    {
        throw new NotImplementedException();
    }

    public void Update(T entity)
    {
        throw new NotImplementedException();
    }
}

初始化

 public class Framework
{
    public Framework()
    {
        DbConfiguration.SetConfiguration(new DbConfig());

        var databaseDirectory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "Test", "Database");
        Directory.CreateDirectory(databaseDirectory);
        var databasePath = Path.Combine(databaseDirectory, "Database.sdf");
        var sqlCeConnectionString = string.Format("Data Source={0}", databasePath);

        var dataContext = new DataContext(sqlCeConnectionString);
        this.Repository = new Repository<TestClass>(dataContext);
    }

    public IRepository<TestClass> Repository { get; set; }
}

我假设您首先使用的是EF代码，并且DataContext类中没有定义DbSet属性

对不起，目前无法查看您的TestApp
