When GC will call in .net?
Ans) In Asp.net GC uses the concept of generations to improve performance. GC will support generations0, generations1 and generations2.
Generation 0 has all the newly created objects. When the application creates objects they first come and fall in the Generation 0 bucket. A time comes when Generation 0 fills up so GC needs to run to free memory resources. So GC starts building the graph and eliminating any objects which are not used in application any more. In case GC is not able to eliminate an object from generation 0 it promotes it to generation 1. If in the coming iterations it’s not able to remove objects from generation 1 it’s promoted to generation 2. The maximum generation supported by .NET runtime is 2.
