Getting error while trying to build the Hello World MsBuild Example

Hi,
BuildXL is using the Microsoft.Build.Prediction library to get some evaluation-time predictions about where an MSBuild project is going to produce outputs into. In this case it seems that the prediction is wrong, and D:\Software\BuildXL\Out\VS\object\Example is a location which doesn't have a policy that allows writes. One option would be to add a configuration mount on that location with write permissions, but I think the easiest is to update the example project with explicit locations where the intermediates and final binaries are going to go E.g.: you could change Example.vcxproj to add OutDir and IntermediateOutputPath as follows:

Example.vcxproj

...
<PropertyGroup>
    <ConfigurationType>Application</ConfigurationType>
    <PlatformToolset>v143</PlatformToolset>
    <OutDir>Bin\</OutDir>
    <IntermediateOutputPath>Object\</IntermediateOutputPath>
  </PropertyGroup>
...

I'll apply a fix to the example to reflect this as well.

Thanks,
Serge.
