在SQL Server CLR程序集中使用Microsoft Solver Foundation

Question

我目前正在编写自己的CLR存储过程,我需要使用Microsoft Solver Foundation的解算器.

为了能够在我的CLR项目中添加对Microsft Solver Foundation的引用,我需要将该程序集添加到我的SQL Server实例(源).所以我安装了MS Solver Foundation Redistributable,并使用以下脚本作为服务器管理员在SQL Server中注册它:

USE MYDB

ALTER DATABASE MYDB SET TRUSTWORTHY ON WITH ROLLBACK IMMEDIATE

ALTER DATABASE MYDB SET TRUSTWORTHY ON

CREATE ASSEMBLY MicrosoftSolverFoundation
AUTHORIZATION dbo
FROM 'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\Microsoft.Solver.Foundation.dll' 
WITH PERMISSION_SET = UNSAFE

但是,我收到以下错误:

Assembly 'MicrosoftSolverFoundation' could not be installed because existing policy would keep it from being used.

这篇 MSDN 帖子似乎讨论了同样的事情，并建议使用mscorcfg.msc工具来查看运行时安全策略。

它还提到了Fusion Log Viewer，用于查看在尝试创建程序集时是否正在记录任何内容。
