How to set up a WEB application developed in C# ASP.NET (.NET Framework) for a server configured in Medium Trust?

Question

Guys, I’m having the biggest headache to host a website, developed in C# ASP.NET (.NET Framework), MVC, on the server of LOCAWEB. Their server is set to Medium Trust and their confidence level is locked with Location allowOverride="false", i.e., I cannot simply declare trust level="Full" on the web.config application level, because it won’t have any effect. They instructed me to declare [Assembly: Allowpartiallytrustedcallers] in the application’s Assemblyinfo.Cs, but it still doesn’t work.

Well, to make it easier to identify and solve the problem, I set up Web.config (machine-level) on my local machine for Medium Trust as well, because theoretically, if I can run on the local machine I will be able to run on the Locaweb server as well. I also created a new application, test only, without including any package or reference to more than the ones already coming when we create the solution, so it is easier to isolate the problem.

Follow the settings of my application:

Error

I’ve researched the problem in several forums, but the solution they always propose is to switch to another server. I don’t think this is the best solution. I believe there is some way to configure the application to run in environment configured with Medium Trust.

I know there are similar questions to that, but I saw that in the other questions the staff did not specify everything and there is also no plausible solution. I hope that through this question someone can give me a north.

Observing: The. Net Framework version is 4.5.

Thanks in advance!
