我收到此错误信息时,我曾经尝试更新或保存我的实体数据模型注册的生成提供:实体框架:无法Web.Config中
ERROR: Unable to register the build provider in Web.Config because of the following exception: 'Object reference not set to an instance of an object.'.
然后,当我尝试运行应用程序我得到:
The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid.
如何修复它以便能够写入到Web.config。我已经通过它精细的梳齿,但我没有提到任何XML破碎。
