Does it make sense in one solution, but in different projects to use different frameworks?

Question

C++ / C#

For example, I want to use Caliburn in one project. Micro, and in another MVVVMLight.
Is it justified? Are there sources that describe this?

Answer 1

If there are no specific conditions for choosing an MVVM framework for a project, then it is better to do projects on one - there will be no need to remember the features of various frameworks.
If the task is just to feel the possibilities of different frameworks - why not?

Answer 2

Justified for the purpose of training, not justified for the purpose of further support.
