will be helpful for those in need I have to register a DLL in a SQL Server from a legacy project, the bad thing is that I don't have the DLL nor the source code, just what I have is the binary string obtained from the Create Scripts option on my database. I'm trying to use the following code:
code :
--You Have to use Dynamic SQL 

USE [master]
DECLARE @CurrentUserName VARCHAR(MAX),@String_SQL NVARCHAR(MAX)
SET @CurrentUserName = SUSER_SNAME()
SELECT @CurrentUserName
--GRANT UNSAFE ASSEMBLY TO @CurrentUserName

SET @String_SQL=''
SET @String_SQL =N'GRANT UNSAFE ASSEMBLY TO '+@CurrentUserName+''

PRINT @String_SQL
EXEC (@String_SQL)

will help you Looking at the documentation from Microsoft in regards to allowing Partially Trusted Callers to Full Trust Assemblies I do not believe that this is going to be possible to do.
You keep stressing that we need to avoid the security concerns, but in all reality, what you are trying to do with your solution is bypass essentially every single portion of the code access security system within the .NET Framework, and I'll be hard pressed to believe that you are going to be able to get a viable solution.

wish help you to fix your issue I'm working on a website where the user can input their username, email, and password on the home page to create their account, then they click "Create Account" and it goes to a php script which checks if any are blank, if a username is taken, and so on, pretty standard stuff. If there is an error when creating the account, would it be unsafe to redirect the user back to the home page with their username and email in the url to fill the inputs back in? , For your specific case, sessions would work best:
code :
session_start();
...
//if username or email taken, save in session
$_SESSION['taken_name'] = $username;
$_SESSION['taken_email'] = $email;

//redirect user
header('Location: home.php');
session_start();
... 
$username = $_SESSION['taken_name']? : null;
$email = $_SESSION['email']? : null;
