我正在尝试在sql程序集中添加类库（c#）。此库正在使用“newtonsoft.json.dll”序列化对象。
当我尝试添加此库时，它抛出错误“assembly'xyz'references assembly'system.runtime.serialization，…”

CREATE ASSEMBLY System_Runtime_Serialization 
FROM 'C:\Windows\Microsoft.NET\Framework64\v3.0\Windows Communication Foundation\System.Runtime.Serialization.dll'
WITH PERMISSION_SET = unsafe
GO

获取此错误：- Assembly 'System_Runtime_Serialization' could not be installed because existing policy would keep it from being used. 仅供参考，使用sql server 2017和.net framework 4.6.1
