@pranavkm Should I move your sample repo into the this repo?

[Rick-Anderson]

@pranavkm quick review when you have time will save you time in the long run :)

Sure, that would be great.

[Rick-Anderson]

Could we call out that this does not work in conjunction

Sorry @pranavkm I mean to add that. I got really ambitious on my last commit so you'll need another look and maybe @mkArtakMSFT too. I'm hoping what I've written will cut down on all that traffic on dotnet/aspnetcore#8737

[Rick-Anderson]

@pranavkm I cloned https://github.com/pranavkm/PageHandlerAuth and copied the code to this repo. But on inspection, in dotnet/aspnetcore#8737 you show the code for your first commit. Just need to verify I need to copy over the code from your first commit. You 2nd commit is much different.

I edited this to be more inline with what was shared in the issue (based on the initial commit). Could you move this to a new file? If you're able to try it out, that would be great. I edited this on GitHub, so I'm not sure if all this compiles \ works correctly.

@blowdart please review Internal review URL and this PR.

@mkArtakMSFT I added the following on my own, please approve:

• When possible, moving shared content to a partial view is the preferred approach.
• There are no plans to support the AuthorizeAttribute on Razor Page handlers.

Yeah, that seems fine to say.
