System.Security.HostProtectionException: 试图执行 CLR 主机禁止的操作

Question

我在 SQLCLR 项目中使用线程，当我尝试运行我的用户定义函数时出现以下错误。我可以做些什么来在我的项目中启用并行库和 await/async 等线程？

Msg 6522, Level 16, State 1, Line 4
A .NET Framework error occurred during execution of user-defined routine or aggregate "CalculateInfo":
System.Security.HostProtectionException: Attempted to perform an operation that was forbidden by the CLR host.

The protected resources (only available with full trust) were: All
The demanded resources were: Synchronization, ExternalThreading

System.Security.HostProtectionException:
at UserDefinedFunctions.getData()
at UserDefinedFunctions.CalculateInfo()

Answer 1

如您在另一个问题中所述，此错误需要以下条件：

ALTER ASSEMBLY [AssemblyName]
   WITH PERMISSION_SET = UNSAFE;
