Version Info

• Stylet version: 1.3.6
• Runtime version: Net 5

Additional Info
I want to use the ABP VNext framework. If the MVVM framework is not applicable, ABP can inject services and access them, but with stylet, ABP services cannot be injected properly. Please help me, I have been working on it for more than two weeks.
