dotnet10: not possible to run dotnet9 projects (can't find net core app 9) #464575
Description
Nixpkgs version
- Unstable (25.11)
Describe the bug
Since I added dotnet 10 (SDK, runtime and aspnetcore) to my dotnet-combined package, I can run projects targeting dotnet 10. But if I try to run a project targetting dotnet 9, I get this error
You must install or update .NET to run this application.
App: /home/gaj/.nuget/packages/swashbuckle.aspnetcore.cli/9.0.6/tools/net9.0/any/dotnet-swagger.dll
Architecture: x64
Framework: 'Microsoft.NETCore.App', version '9.0.0' (x64)
.NET location: /nix/store/9pa71r5z5sw8z63x1ci4s08b9bj22cz5-dotnet-sdk-10.0.100/share/dotnet/
The following frameworks were found:
10.0.0 at [/nix/store/9pa71r5z5sw8z63x1ci4s08b9bj22cz5-dotnet-sdk-10.0.100/share/dotnet/shared/Microsoft.NETCore.App]
My dotnet combined package is defined as
with pkgs.dotnetCorePackages;
combinePackages [
runtime_6_0-bin
runtime_7_0-bin
runtime_8_0-bin
runtime_9_0-bin
runtime_10_0-bin
aspnetcore_6_0-bin
aspnetcore_7_0-bin
aspnetcore_8_0-bin
aspnetcore_9_0-bin
aspnetcore_10_0-bin
#sdk_9_0-bin
sdk_10_0-bin
pkgs.openldap
]
Before upgrading to dotnet10, so, with dotnet 9 SDK, there was no problem running projects targetting older frameworks.
Steps to reproduce
Use the combined net core packages described above. Create a dotnet project targeting dotnet 9. Try to run the project.
Expected behaviour
The correct dotnet9 binary should be found and the project should run
