使用分布式缓存（SQL Server）时，ASP.NET Core RC2在完整的.NET Framework上崩溃

Question

我有一个使用ASP.NET Core RC2和dotnet CLI的Web项目，目标是.NET Framework，该项目刚刚从ASP.NET 5 RC1和DNX更新。 一旦使用分布式SQL Server缓存，它就会崩溃，但出现以下异常：

FileNotFoundException：无法加载文件或程序集'System.Collections.NonGeneric，版本= 4.0.0.0，区域性=中性，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connectionString）

与堆栈跟踪：

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）系统.Data.SqlClient.SqlConnection.ConnectionString_Set（DbConnectionPoolKey键）System.Data.SqlClient.SqlConnection.set_ConnectionString（字符串值）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（字符串键）Microsoft.AspNetCore.Session.DistributedSession.Load（）Microsoft。 AspNetCore.Session.DistributedSession.Remove（字符串键）MYCODE.SessionHelper.SetVa MYCODE.cs中的lue（字符串键，字符串值）等

该行实际上只是Session.Remove(key); 。

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

在dependencies项中为Microsoft.NETCore.Platforms （ 1.0.1-rc2-24027 ）和/或NETStandard.Library （ 1.5.0-rc2-24027 ）添加条目没有帮助。 由于不存在描述该操作方法的文档，因此在针对.NET Framework时我可能做错了。 唯一的问题是什么？ 我是否缺少导入或参考程序集或其他内容？

Answer 1

我不确定到底是什么解决了这个问题，但是删除dnx451导入并转到net451还是可以的。 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dotnet ef工具- 必须将其制作为应用程序才能执行该操作，并进行一些配置更改，并简单地清空bin和obj文件夹最终清除了所有内容。
