（无法修复）程序集存在于 SQL Server 2014 上，但它声称没有它
(Unfixable) Assembly exists on SQL Server 2014 but it claims it doesn't have it
更新： 这个问题无法修复：https://connect.microsoft.com/SQLServer/Feedback/Details/809697
我正在尝试使用 .net 4.5 创建一个 SQL CLR 程序集，它告诉我它丢失了 system.servicemodel（即使它在 .net 程序集文件夹中）：
Assembly 'MySQLCLRProject' references assembly 'system.servicemodel, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089.', which is not present in the current database. SQL Server attempted to locate and automatically load the referenced assembly from the same location where referring assembly came from, but that operation has failed (reason: 2(The system cannot find the file specified.)). Please load the referenced assembly into the current database and retry your request.
所以我手动添加一个 4.5,4.5.1,4.5.2 System.ServiceModel.dll 到项目文件夹，然后它告诉我它丢失 system.servicemodel.internals:
Warning: The Microsoft .NET Framework assembly 'system.servicemodel, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089.' you are registering is not fully tested in the SQL Server hosted environment and is not supported. In the future, if you upgrade or service this assembly or the .NET Framework, your CLR integration routine may stop working. Please refer SQL Server Books Online for more details.
Msg 10301, Level 16, State 1, Line 13

Please load the referenced assembly into the current database and retry your request.
所以我添加了一个 4.6 System.ServiceModel.dll 它会告诉我它丢失了 system.xaml:

在我添加 system.xaml (4.5-4.6.1) 之后，它告诉我：

我搜索了所有地方，但没有找到任何解决这个问题的方法。我什至完全用 .net 4.5 重新创建了这个项目，但它仍然给我带来问题。
感谢任何帮助，谢谢！
此处的问题是您正在尝试使用不受支持的 .NET Framework 库：ServiceModel。该库在 SQL Server 2005、2008 和 2008 R2 中确实有效。但是，由于它不在 "supported" 列表中，因此不能保证它适用于所有 .NET Framework 升级。它曾经是纯 MSIL 程序集，但后来他们将其更改为混合模式程序集，并且无法加载到 SQL 服务器。
此问题已记录在此处的 Stack Overflow 上：
