When the project is upgraded to VS2010 or 2012 (and the NET version is also upgraded to 4.0), the following error message is displayed:

The "XXX" type violates the inherited security rules. The derived type must match the Security accessibility of the base type or be less accessible than the base type.

 

Solution 1:

In fact, it is very easy to add the following information to the AssemblyInfo. cs file of the XXX project:

[Assembly: System. Security. SecurityRules (System. Security. SecurityRuleSet. Level1)]

Solution 2:

Create a new class library to generate the AssemblyInfo. cs file comparison. Found

If the AssemblyInfo. cs file exists in XXX project

[Assembly: AllowPartiallyTrustedCallers]

Delete or comment it out.
