Question

我目前正在使用VWD 2010 Express并且有兴趣更详细地探索WCF REST，但我找不到“ADO.NET实体数据模型”模板或任何有关如何安装它的信息。这也被称为ODATA实体框架是否正确？我想使用SQL Express数据库创建一个WCF REST服务，后来又创建一个MySQL数据库。

我搜索了在线模板网站，但没有在那里看到它。

顺便说一下，我现在最感兴趣的是VB模板。

此外，假设ODATA EF可以与MySQL数据库一起使用是否准确？是否有专门针对MySQL的备用模板？

*的更新 * 根据Ian Michael William的建议，我尝试安装WcfDataServices.exe。安装在日志文件中失败：

Answer 1

用于创建OData服务的Microsoft堆栈称为“WCF数据服务”，不要与“WCF服务”或“WCF RIA服务”混淆。我相信VWD 2010 Express确实有一个用于创建新“WCF数据服务”的模板。

我们强烈建议开发人员依赖我们的NuGet包，我同样建议您使用EF Code First使您的生活更轻松，而不是处理“ADO.NET实体数据模型”。

我最近计划在博客上发表这篇文章。如果你能等那么久，我会尝试写下博客文章并在今晚发布。（示例将在C＃中，但不会有任何复杂的内容，因此应该很容易转换为VB.NET。）

我相信有一些提供商可以帮助EF使用MySQL。我听说他们的质量不一样，但我自己没试过。 DevArt在这个领域一直都很流行。

当我收到博客文章时，我会更新这个答案。

如果您在此处运行WCF Data Services 5.0安装程序：

...您应该会看到VWD 2010 Express的VB和C＃项目模板出现在“网络”项目中。

VATA 2010 Express的ODATA EF在哪里？
