Hi All,
I want to upgrade .netcore2.1 to 3.1, i changed the target framework and all, build is success now.But when i am running the application getting error
Unable to load one or more of the requested types.
Method 'GetFallbackPolicyAsync' in type 'CSP2.Core.CSPAuthPolicyProvider'
from assembly 'CSP2.Core, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=null' does not have an implementation..
in MIcrosoft.netcore.authntication.
Any solution to do the migration?
 
If you had pull down any nuget packages as part of your project, try doing a fresh download. Or try upgrading the packages.
