What are the application lifecycle methods in Blazor?

There are around seven lifecycle methods available in Blazor, which provides synchronous as well as asynchronous lifecycle methods.

OnInitialized ()

This is the synchronous method executed when the component is initialized.

OnInitializedAsync()

This is the asynchronous method executed when the component is initialized.

OnParametersSet()

This is the synchronous method when the component has received the parameter from the parent component.

OnParametersSetAsync()

This is an asynchronous method when the component has received the parameter from the parent component.

ShouldRender()

This method is used to suppress the refreshing of the UI. If this method returns true, then the UI is refreshed. Otherwise, changes are not sent to the UI. It always does the initial rendering despite its return value.

OnAfterRender(bool firstRender)

This is the synchronous method executed when the rendering of all the references to the component is populated.[JB1]

OnAfterRenderAsync(bool firstRender)

This is the asynchronous method which is executed when the rendering of all the references to the component is populated.
