问题描述
(VS2013 upd 4，LS VB Project)
只是为了提前澄清，我通过良好的旧清理/重建解决了这个问题，但是每次在现有表中添加新属性时，我都会在每个最近使用的项目中(而不是在较旧的项目中)收到此错误:
类'< EntityName>'必须实现阴影属性< PropertyName>为< PropertyType>'接口'< EntityName> .DetailsClass.IImplementation'
< EntityName>中的简单属性与关系/导航属性相同.类(在ApplicationDataObjectContext.vb文件中)总是缺少新的属性定义.
我可以创建新表，并成功构建并运行它，但是如果以后再向该新表中添加属性，则会出现相同的错误.
清理/重建解决方案后，错误消失了，但是当我在客户端屏幕上更改某些内容时，我得到:
类'ApplicationData'必须声明为'MustInherit'或重写以下继承的'MustOverride'成员:
Microsoft.LightSwitch.ClientGenerated.Implementation.DataServiceContext:
受保护的MustOverride函数CreateEntityImplementation(Of as Microsoft.LightSwitch.IEntityObject)()作为Microsoft.LightSwitch.Internal.IEntityImplementation
Microsoft.LightSwitch.ClientGenerated.Implementation.DataServiceContext:
受保护的MustOverride子InitializeDataServiceContext()
随之而来的是很多错误.
再次，清理/重建，一切正常.
没有项目升级，没有RIA服务，没有外部数据源，没有VS的最新更新，项目文件夹上没有用户访问问题.
破坏性服务器项目对Microsoft.Lightswitch.dll 10.0.12.1版，较旧的工作项目10.0.12.0版的引用.
有人建议总是清理/重建真的很痛苦吗?
(VS2013 upd 4, LS VB Project)
Just to clarify in advance, I solve this problem with good old clean/rebuild but I get this error in every recently used project, not in older projects, every time I add a new property in existing Tables:
Class '<EntityName>' must implement 'Shadows Property <PropertyName> as <PropertyType>' for interface '<EntityName>.DetailsClass.IImplementation'
It's the same for simple properties as for relations/navigation properties, in <EntityName> Class (in ApplicationDataObjectContext.vb file) new property definition is always missing.
I can create new Table, build and run successfully, but if later I add a property to this new Table I get the same error.
After clean/rebuild solution the error disappears but as I change something on Client screens I get:
Class 'ApplicationData' must either be declared 'MustInherit' or override the following inherited 'MustOverride' member(s):
Microsoft.LightSwitch.ClientGenerated.Implementation.DataServiceContext :
Protected MustOverride Function CreateEntityImplementation(Of T As Microsoft.LightSwitch.IEntityObject)() As Microsoft.LightSwitch.Internal.IEntityImplementation
Microsoft.LightSwitch.ClientGenerated.Implementation.DataServiceContext :
Protected MustOverride Sub InitializeDataServiceContext()
Followed by a lot of consequent errors.
Again, a clean/rebuild and everything works.
No project upgrade, no RIA services, no external Data Source, no recent updates to VS, no user access problems on project folder.
Breaking server projects reference to Microsoft.Lightswitch.dll v. 10.0.12.1, older working projects v. 10.0.12.0.
Is really painful always going clean/rebuild, any suggestion?
