DSC depends on vcruntime140.dll but does not declare it #1244
Description
Every executable in the DSC package has a load time dependency on vcruntime140.dll, which it probably does not need. It works on most machines by virtue of other applications installing such DLL in system32. It will not work on a clean machine.
You can work around this by statically linking components of the C++ runtime, while still dynamically linking the C runtime. This is referred to as the "Hybrid CRT" model.
Here's how you do it in Rust:
...and here's how you do it in MSBuild/vcxproj:
A little more information is available in the WinAppSDK docs, but be aware that you do not need to consume WinAppSDK to use HybridCRT.

This was reportedly fixed in #269, but it seems to have regressed.

as of 3.1.2 dsc.exe now fails to run if VCRUNTIME140.dll is not found.
3.1.1 works as normal, i tested this on a fresh windows server 2025 standard installation.
are we expected to also install Visual C++ Redistributable starting with 3.1.2 or is this a bug?
