ALTER AUTHORIZATION ON DATABASE::mydb TO sa;
ALTER DATABASE [myDB] SET TRUSTWORTHY ON
GO

Answer 2

Build your project with ANY CPU configuration. I had this problem when compiled my own project with x86 configuration and tried to run it on x64 SQL server.

Answer 3

Applied all of the above suggestion and it failed. Then I recompiled my source code with "Any CPU" option, and it worked!

Answer 4

Does your assembly do file I/O? If so, you must grant the assembly permission to do this. In SSMS:

1. Expand "Databases"
2. Expand the node for your database
3. Expand "Programmability"
4. Expand "Assemblies"
5. Right-click your assembly, choose Properties
6. On the "General" page, change "Permission set" to "External access"

Answer 5

Ran the SQL commands below and the issue appears to be resolved.

USE database_name
GO

EXEC sp_changedbowner 'sa'
ALTER DATABASE database_name SET TRUSTWORTHY ON
