Add Trusted Assemblies to SQL Server 2022
Since SQL Server 2017, Microsoft introduced the clr strict security
option. This option is enabled by default and requires that all assemblies loaded into SQL Server are signed by a certificate. This is a security feature that helps protect your database from malicious code.
When you migrate a database to SQL Server 2017 or later, you may need to load assemblies that are not signed by a certificate. In this case, you need to add the assemblies as trusted assemblies to SQL Server.
