Install location for x64 emulated on Arm64
We've moved the install location of the x64 version of the .NET SDK and runtime on Arm64 hardware.
Previously, the x64 and Arm64 versions installed to the same location, leading to a broken state. In addition, the
PATH environment variable value was being set for both installations, so depending on install order, you might have an unexpected version of the
dotnet command used by default.
.NET 6 RC 2
In previous versions, both the Arm64 and x64 versions of .NET SDK and runtime installed to the same location on Arm64 hardware:
- macOS: /usr/local/share/dotnet
- Windows: %ProgramFiles%\dotnet
This worked if only one version was installed, but was completely broken if both were installed.
In .NET 6, the x64 version of .NET installs to a subfolder named x64 on Arm64 hardware:
- macOS: /usr/local/share/dotnet/x64
- Windows: %ProgramFiles%\dotnet\x64
For more information, see Install location.
This change may affect source compatibility.
Reason for change
Without this change, the x64 and Arm64 versions of the .NET SDK and .NET runtime install to the same location on Arm64 hardware. This leads to being in a completely broken state. This change allows customers to develop for both x64 and Arm64 at the same time.
If you need to use the x64 version of the
dotnet command, manually add that file path to the
PATH environment variable.
