Blazor Startup Class

S Chapman 82 41

I'm looking at Blazor Server app and in particular exploring the auto-generated source code. I have found that renaming the methods in Startup class causes an exception and the app won't load. The Startup class is passed to the host only in the form of a delegate and is accessed when the HostBuilder is built and run from inside the framework. This means the framework is assuming the names of the methods in the Startup class. Does anyone else find this to be odd? I would have expected an interface to be published and the Startup class to implement that interface. Am I missing something basic here?

Hi @S Chapman 82 ,

I have found that renaming the methods in Startup class causes an exception and the app won't load.

If it is convenient, can you provide detailed code about that part and what method do you need to rename? This will be more helpful for us to solve your problem, thank you.

Sorry if my post wasn't clear but what I was highlighting is, if we rename the methods of Startup class intentionally or otherwise, the compiler won't catch the errors, but, at run time there is an exception. This is not ideal in my view. I would have expected an interface to be defined and used by the framework and for the Startup class to implement that interface.

I don't think that is a good idea, you can see the detailed information about startup.
