The examples/QIR/Development is not updated for Rust Q#RT.

The dir examples/QIR/Development build fails like this:

upon update to a newer QDK ver like this in examples/QIR/Development/Development.csproj.

The update is needed in Q# compiler for generating build/Main.cpp.

---

Also pay attention that clang version 11.0.0 is used on Linux instead of 14 or newer.

If the examples/QIR/Development/Development.csproj is kept at the older QDK version (0.25.228311) then we get a version conflict between different .csproj projects of examples\QIR\QIR.sln like this (see extract below). The whole QIR.sln has to stay at an older QDK version:
