Hi,

It usually happens on hosting services that can restrict what can be done for saferty reasons. You should likely see with those in charge of providing you with this service (either inside or outside of your company) to see what is in place. For a quick overview of this "partial trust" feature see for example :

You kept old files on the server or you moved them on your own machine? If I remember a security policy could check from which "zone" comes a file. Try perhaps https://thirtysix.zendesk.com/hc/en-us/articles/202921675-How-to-Unblock-a-File-Downloaded-from-an-Email-or-the-Internet (not 10% sure it is related but it may worth to give it a try).

If it still doesn't work, it will be likely easier to get in touch with those managing this security policy to see what needs to be done rather than trying to guess.

My best guess is the connection string is configured to use integrated security while developing on your local machine but the original connection string uses SQL login.  Take a look at the connection string in the original web.config.

Hi dandi.box,

According to your error message, I recommend that you can choose 'This is a full trust application' option.

You can refer to these links:

Request for the permission of type 'System.Security.Permissions.SecurityPermission'

Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=4.0.0.0

Best Regards,

YongQing.

Hi dandi.box,

This pop-up box only appeared before version 4.0. If you can't find it, you can try using code to apply the function.

In the web.config of your project, add the following statement to set a higher trust level for asp.net:

<configuration>
     <system.web>
          <trust level ="Full" />
     </system.web>
</ configuration>

For more details, you could refer to this link : Changing the ASP.NET Trust Level
