Blazor components have a well-defined lifecycle, with several methods that are invoked at specific stages during the component's creation, rendering, and destruction. 

These lifecycle methods allow developers to hook into these stages and perform necessary actions or logic. 

 

Among the main lifetime techniques in Blazor components are:

• OnInitialized: Called once upon component initialisation,  OnInitialized is appropriate for doing initial setup or data retrieval.
• OnParametersSet: Called anytime the component's parameters change, hence allowing developers to react to parameter changes.
• OnAfterRender: Offered an option to do post-render activities or engage with the DOM, called after the component has been rendered.
• Dispose: Executed when the component is about to be removed from the UI, Dispose lets developers end running activities or clear up UN-managed resources.
   

Using these lifecycle techniques, developers may guarantee that their components function as planned all during their lifetime, hence producing more strong and maintainable Blazor applications.
