Question

What improvements are prepared in CAS in .NET 4.0?

Answer 1

The CAS method in .NET is utilized to organize and construct the capability of managed code. Previously, this policy was valid for only local applications, the security warranty was restricted. Thus, developers used to see for alternate solutions, like operating system-level solutions. This problem was resolved in .NET Framework 4.0 through turning off the machine-wide security. The shared and hosted Web applications can now execute more steadily. The security policy in .NET Framework 4 is been simplified by the transparency model. This model permits you to execute the Web applications exclusively of with no reference to CAS policies.

As a result of security policy modifies in .NET Framework 4.0, you may come across runtime exceptions compilation and advices, if you attempt to use the out of date CAS policy types and members either implicitly or openly. Though, you can keep away the warning and faults with use of the <NetFx40_LegacySecurityPolicy> configuration element in the runtime situations to choose into the outdated CAS policy actions.
