实体框架中的可插拔约定 [英] Pluggable Conventions in Entity Framework

问题描述

我正在追踪 EF Feature CTP5：可插入约定创建自定义可插入约定（在这种特殊情况下可以更改所有十进制字段的精度）。

I am following EF Feature CTP5: Pluggable Conventions to create custom pluggable convention (in this particular case to change the precision of all decimal fields).

看起来像最新版本的EF 在上添加方法ConventionsConfiguraions 也是internal。我现在添加自定义可插入约定？

Looks like in the latest release of EF the Add method on ConventionsConfiguraions is also "internal'. How do i add custom Pluggable Conventions now?

推荐答案

该功能已在EF 4.1中删除，可能的实施推迟到以后的版本：

The feature has been removed in EF 4.1 and a possible implementation postponed to a later release:

代码首先可定制（可插拔）
约定不支持
支持默认的Code First
约定。

Code First customizable (pluggable) conventions are not supported. Removing the default Code First conventions is supported.

And：

删除代码第一个可插拔约定可插拔约定功能CTP5中预览了
，但
在
版本中没有实时质量。此版本仍然支持
删除默认约定。

Removal of Code First Pluggable Conventions. Pluggable Conventions were previewed in Feature CTP5 but were not at go-live quality for this release. This release still supports the removal of default conventions.

这就是为什么添加不再作为 ConventionsConfiguration 的公共方法存在，只有删除仍然是可用。

That's why Add doesn't exist anymore as a public method of ConventionsConfiguration, only Remove is still available.
