我有一个使用 ASP.NET Core RC2 和 dotnet CLI 的 Web 项目，针对 .NET Framework，刚刚从 ASP.NET 5 RC1 和 DNX 更新。一旦我使用分布式 SQL Server 缓存，它就会崩溃并出现以下异常：

FileNotFoundException：无法加载文件或程序集“System.Collections.NonGeneric，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b03f5f7f11d50a3a”或其依赖项之一。该系统找不到指定的文件。
System.Data.SqlClient.SqlConnectionString..ctor（字符串连接字符串）

使用堆栈跟踪：

System.Data.SqlClient.SqlConnectionString..ctor(String connectionString) System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) System .Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) System.Data.SqlClient.SqlConnection.set_ConnectionString(String value) System.Data.SqlClient.SqlConnection..ctor(String connectionString) Microsoft.Extensions.Caching.SqlServer.DatabaseOperations.GetCacheItem （字符串键，布尔值 includeValue）Microsoft.Extensions.Caching.SqlServer.DatabaseOperations.GetCacheItem（字符串键）Microsoft.Extensions.Caching.SqlServer.SqlServerCache。Get(String key) Microsoft.AspNetCore.Session.DistributedSession.Load() Microsoft.AspNetCore.Session.DistributedSession.Remove(String key) MYCODE.SessionHelper.SetValue(String key, String value) in MYCODE.cs 等

这条线实际上就是Session.Remove(key);.

我怀疑它出于某种原因试图加载 .NET Core 包，而不是意识到它可以使用 .NET Framework。下面是我的project.json。

Microsoft.NETCore.Platforms在( 1.0.1-rc2-24027) 和/或NETStandard.Library( 1.5.0-rc2-24027) 中添加条目dependencies没有帮助。由于描述如何执行此操作的文档缺乏甚至不存在，因此我可能在针对 .NET Framework 时做错了什么。唯一的问题是什么？我是否缺少导入或参考程序集或其他东西？

我不确定究竟是什么解决了这个问题，但删除了dnx451导入并开始net451工作。这引发了另一个问题，即我用于数据库和迁移的类库将无法运行该dotnet ef工具 -必须将它制作成一个应用程序才能执行此操作，并进行一些配置更改并简单地清空 bin 和obj 文件夹最终清理了一切。
