NET Framework 4.5:policy to allow full trust for all Intranet assemblies

Hello dear,

Using new 4.5 Framework .NET I don't be able to se my user control hosting in a web page (client and server side both).

In the past I fixed this problem following the instruction that I found in those post & blogs:

"To modify the policy to allow full trust for all Intranet assemblies:

• Expand the All_Code code group
• Right click the LocalIntranet_Zone code group, and select properties
• Switch to the Permission Set tab, and select FullTrust

"

I've used caspol and I've tried to set  <NetFx40_LegacySecurityPolicy enabled="true"/> without success.

Anyone could help me please?

Thank you!

Gianluca.
