EntityConnectionStringBuilder和ProviderManifestToken的问题 [英] Issue with EntityConnectionStringBuilder and ProviderManifestToken

问题描述

我正在使用此代码

 
 EntityConnectionStringBuilder entityBuilder =  new  EntityConnectionStringBuilder（）; 
 entityBuilder.Provider = " System.Data.SqlClient" ; 
 entityBuilder.ProviderConnectionString = connectionString; 
 entityBuilder.Metadata =  @" res：// *" ; 
  var  objContext =  new  StsSecurityEntities（entityBuilder.ToString（））; 
 

解决方案

史蒂夫，

还有其他参考资料在项目中可以查看不同的SSDL。 请参阅：

-   npgsql库时实体数据源中运行时出错...

Visual Studio中的输出是否显示任何其他SSDL被无意中引用？

此外，看看这个：

I am using this code

EntityConnectionStringBuilder entityBuilder = new EntityConnectionStringBuilder();
entityBuilder.Provider = "System.Data.SqlClient";
entityBuilder.ProviderConnectionString = connectionString;
entityBuilder.Metadata = @"res://*";
var objContext = new StsSecurityEntities(entityBuilder.ToString());

解决方案

Hi Steve,

Are there any other references in the project that could be looking at a different SSDL.  See:

- Error at runtime in Entity Datasource when npgsql library ...
http://social.msdn.microsoft.com/Forums/en-US/adodotnetentityframework/thread/a9e382bc-d272-4717-bc71-17b4dc743b29

Does the output in Visual Studio show you that any other SSDL is being inadvertently referenced?

Also, take a look at this:
