Installed .NET 10 preview, can't publish projects that are .NET 9

Hi,

I installed .NET 10 preview, now I can't publish my projects that are .NET 9.

I get these errors:

Task "Error" skipped, due to false condition; (('$(CurrentSolutionConfigurationContents)' == '') and ('$(SkipInvalidConfigurations)' != 'true')) was evaluated as (('<SolutionConfiguration>
Task "Error" skipped, due to false condition; ('$(MSBuildToolsVersion)' == '2.0' and ('$(ProjectToolsVersion)' != '2.0' and '$(ProjectToolsVersion)' != '')) was evaluated as ('Current' == '2.0' and ('' != '2.0' and '' != '')).

I have a global.json file in the solution folder which specifies that it should build for .NET9

Seems like it's using .NET10 to compile

TeBeCo•8/1/25, 9:14 AM

try to also install net 9 sdk

TeBeCo•8/1/25, 9:20 AM

global json is forcing the sdk that needs to be present

TeBeCo•8/1/25, 9:20 AM

you will probably want to look at global json doc if you want funky roll forward

TeBeCo•8/1/25, 9:21 AM

can't you share the repo link ?

TeBeCo•8/1/25, 9:21 AM

as well as the output of
dotnet --info
form the place it fails

OlssonOP•8/1/25, 10:51 AM

I have .NET9 sdk and specifically the version im using in the global json

TeBeCo•8/1/25, 11:22 AM

can you do that / share that / share someone a similar repo link that fail

TeBeCo•8/1/25, 11:22 AM

with roughtly similar stack inside as well

TeBeCo•8/1/25, 11:23 AM

and what command lines are you invoking that fails

TeBeCo•8/1/25, 11:24 AM

-
so far you shared the error only, not the context it selt (repo / stack / csproj / command line)

TeBeCo•8/1/25, 11:24 AM

the only answer you might see are "i don't know, it works for me"

TeBeCo•8/1/25, 11:24 AM

my guess is that you have something else specific

TeBeCo•8/1/25, 3:15 PM

@Olsson ?

OlssonOP•8/1/25, 3:54 PM

It was resolved. Forgot abou working directory, so the json was never found
