LGTM - thank you @nttDamien - was that all of it btw (i.e. just in the enablement.md doc)?

Hi @nttDamien I think the only last 2 references I can find we could just rid are in those 2 links

carbon-aware-sdk/casdk-docs/docs/overview/enablement.md

Line 591 in 4192933

[the Secret Manager tool](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets?view=aspnetcore-6.0&tabs=windows#secret-manager)

replace https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets?view=aspnetcore-6.0&tabs=windows#secret-manager with https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets?tabs=windows#secret-manager

and ...

> [default .NET configuration](https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-6.0#default-application-configuration-sources)

replace https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-6.0#default-application-configuration-sources with

[default .NET configuration](https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?#default-application-configuration-sources`

I checked, it defaults to the latest GA version (so 8 at the mo) and I think we can leave it going forward...

Could you apply these 2 as well so I can merge please?

Thanks again for this already

I checkd the files suggested by Sophie and for most no change was required. Although I doubt myself now that you found two places I missed ...

@nttDamien I checked everything for key terms and this was the last thing I could find just using 6.0... I think if we update these 2 things we should be good - (we are probably good without it too given you can change the version when you get to that page)
Lets discuss this morning

Great thanks @nttDamien
