from

clang and msbuild integration

chapter 12 of "Inside the Microsoft Build Engine" describes how you can add mingw toolchain to msbuild (visual studio 2010 and newer versions)
So I was very glad to see this patch. But it seems that it does not contains nothing usefull and just don't works !
I wonder if there are some way to integrate clang with msbuild. I missed something ?

Inside the Microsoft Build Engine

it seems that book contains huge amount of misprints. for example on page 79:

The syntax when accessing a static property would be as follows:
$({ClassName}::{PropertyName})

o`k, lets check sample of using static properties:
<Message Text="DataTime.Now: $([System.DateTime]::Now)"/>
and below in PropertyFunctions02.proj was used GetPathToSystemFile('msbuild.exe') but output shows path to mspaint.exe
