I am deploying an ASP.NET application that currently runs in a full trust environment. The hosting provider supports high trust, but not full trust. I need to adjust my application to comply with high trust requirements.

My application is hosted on a shared environment using Plesk with AccuWebHosting. The environment supports high trust but not full trust.now they told me i need to modify the parts of the code that are full trust ,How can I modify my code to ensure compatibility with high trust?
“Are there specific areas in ASP.NET applications that commonly need adjustment when moving from full trust to high trust?”
“How can I test my application effectively in a high trust environment before deployment?”
