Description
Describe the bug
When using the new SDK hint path feature, the SDK resolver is setting DOTNET_EXPERIMENTAL_HOST_PATH to the machine-global path instead of the one associated with the resolved SDK.
To Reproduce
In dotnet/msbuild after dotnet/msbuild#11970 and using an int preview VS with the updated resolver:
❯ msbuild -getProperty:DOTNET_EXPERIMENTAL_HOST_PATH -getProperty:DOTNET_INSTALL_DIR .\src\Framework\ -bl
{
"Properties": {
"DOTNET_EXPERIMENTAL_HOST_PATH": "C:\\Program Files\\dotnet\\dotnet.exe",
"DOTNET_INSTALL_DIR": "S:\\msbuild\\.dotnet\\"
}
}There's another property that's set correctly DotNetTool = S:\msbuild\.dotnet\dotnet.exe, but that's not the one the Csc task chooses to invoke.
If the local SDK is newer than any globally installed one, this can lead to bugs like:
