I am using Microsoft SQL Server 2017 Express edition and Visual Studio 2017.

I followed this tutorial https://www.youtube.com/watch?v=nczucm60YF0&t=2s, but I get this error:

Executing publish script on database 'database name'

Full message is:

Creating [SQLCLRUDTypeDemo]... (94,1):
SQL72014: .Net SqlClient Data Provider:

Msg 10343, Level 14, State 1, Line 1
CREATE or ALTER ASSEMBLY for assembly 'SQLCLRUDTypeDemo' with the SAFE or EXTERNAL_ACCESS option failed because the 'clr strict security' option of sp_configure is set to 1. Microsoft recommends that you sign the assembly with a certificate or asymmetric key that has a corresponding login with UNSAFE ASSEMBLY permission. Alternatively, you can trust the assembly using sp_add_trusted_assembly.

(94,0): SQL72045: Script execution error.
The executed script:

An error occurred while the batch was being executed.

What is the solution? I didn't find this problem anywhere. I found with an error in SQL Server, but not in C#.

    Assembly use for CLR types must be signed or the security option disabled. **Read and search for the actual/relevant error**: “CREATE or ALTER ASSEMBLY for assembly '..' with the SAFE or EXTERNAL_ACCESS option failed because the 'clr strict security' option of sp_configure is set to 1...” - after searching for the relevant error, what question(s) remain? – user2864740 Jan 19 '20 at 20:58
  • I tried with exec sp_configure 'clr enable', 1 reconfigure but it gives me an error. I solved with this: EXEC sp_configure 'show advanced options', 1 RECONFIGURE; EXEC sp_configure 'clr strict security', 0; RECONFIGURE; – BeginnerCoding Jan 19 '20 at 21:06

There error is not in .NET or C#. This is a permissions error coming from SQL Server. When searching for info on errors in SQL Server, you should, at the very least, include the "Msg" number and "Level". For example: "Msg 10343, Level 14" should be part of what you search for, including the double-quotes. It also helps to include "SQL Server" as part of the search term.

For info on how to properly sign and publish SQLCLR assemblies without disabling security (and even within the context of Visual Studio), please see my answer to another S.O. question, especially the second part (below the horizontal line):
