Article: Customizing AppDomain Creation

Posted by Gaurav Khanna on February 26, 2007

Did you have a scenario where you wished you could customize the creation of AppDomains? Or, you could control how many AppDomains any code that runs in your application context (e.g. if you are writing a plugin load framework) could create? Or, how about reusing AppDomains for various assemblies?

I have just finished an article on how any of the above scenarios can be accomplished using the System.AppDomainManager type, introduced in .NET Framework 2.0, by intercept AppDomain creation requests.

How the SSCLI [a.k.a. Rotor] managed "new" works

Posted by Gaurav Khanna on February 12, 2007

One of the best ways to understand how the CLR works internally is to have a look at the SSCLI [a.k.a Rotor] source code.

In How the SSCLI [a.k.a. Rotor] managed “new” works, I have used Rotor source code to discuss what happens behind the scenes when you use the managed new operator to instantiate a managed type, discussing implications of object size, how requests from multiple threads are handled, the different validations that are done, when out-of-memory exception is thrown, etc. If you are a managed code developer, you may learn a thing or two that can help you write better code besides understanding how the managed allocation works internally.
