@WodansSon or @magodo can this be reviewed and released?
dotnet 10 was released yesterday

[ilmax]

It would be great to get this merged soon. 🙂
I’ve also been wondering about the value of doing this kind of client-side validation in the provider. Why not rely on the underlying API to handle it, or offer an option to disable the validation, instead of requiring a switch to the AzAPI provider to achieve the same result?

I’ve also run into situations where deploying an application that targets a newer .NET version forced me to upgrade the provider unexpectedly, adding extra work that wasn’t planned.

[pregress]

@jackofallops can you have a look?

[ossentoo]

.NET 7.0 (STS) no longer supported on Azure Web apps:

I would suggest this should be removed.

[psyvision]

I'm not sure what the route to deprecation is here, v6 is also still in the provider but not available either.

[hangar18rip]

Maybe making some cleanup is not as urgent as adding this new version.

And what would be the impact of removing older versions on running webapps / functions / else ?

[ncook-hxgn]

I agree with hangar18rip. 🎸
Adding versions = feature, removing versions = breaking change.

[ossentoo]

I understand. I suggest my comment be ignored then. Better that this doesn't become a breaking change

[hangar18rip]

hi @WodansSon / @magodo. what's the plan for this PR please ?

[VultureJD]

Why does this always take so long every year? .NET releases are very well-known in advance and Azure has had Day 1 support for the last several years, so why can’t azurerm? This PR alone has been sitting here for over 2 weeks with next to 0 movement. Can it just be approved please?

[pregress]

@sreallymatt maybe you can have a look?

[jackofallops]

Thanks @psyvision and @sreallymatt - LGTM 👍
