Recently, our .Net client libaray is upgrading to compile against Net 4.0. After change the target framework to 4.0, the application has some compilation error.
In AssemblyInfo.cs:
[assembly: SecurityPermission(SecurityAction.RequestMinimum, Execution = true)]
Error 7 Warning as Error: 'System.Security.Permissions.SecurityAction.RequestMinimum' is obsolete: '"Assembly level declarative security is obsolete and is no longer enforced by the CLR by default. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information."' `
In .Net 4.0, it shows that: SecurityAction.RequestMinimum as obsolete, and we treat all warning as error.
What I should do with it? - Just remove it(will this has some unexpected impact? for example when the dlls are used in IIS) or change to some other value? I am not familiar with .Net, especially its security mechanism.
Anyone can help on this? Thanks for any advice and comment :)
