[10.0-rc.1] dotnet run no longer accepts Windows path separators on Linux #50828
Description
Describe the bug
I have a simple console project that I've just updated to .NET 10 RC.1 with a layout like this:
global.json
MyProject.slnx
Run.ps1
src/
MyProject/
MyProject.csproj
Program.cs
Note that while simple, this was a .NET 9 project so hasn't been changed to adopt the new Program.cs support style of program.
I then have a PowerShell script that builds and runs the project like so:
dotnet run --configuration Release --project .\src\MyProject\MyProject.csproj $argsThis works fine on Windows, but on Linux it fails with the following error:
The provided file path does not exist: .\src\MyProject\MyProject.csproj.
If I change the PowerShell script to the following, it works:
- dotnet run --configuration Release --project .\src\MyProject\MyProject.csproj $args
+ dotnet run --configuration Release --project ./src/MyProject/MyProject.csproj $argsIt appears that the .NET 10 SDK is no longer normalizing the path separators.
Changing to / does work on Windows though - it's just \ on Linux that no longer works.
To Reproduce
Create a folder structure with the above layout and run the specified command.
Exceptions (if any)
None.
