Hello, I was maintaining the Visual Studio solution for the runtime and doing Windows development for a while but haven't kept up for a number of years now. We've had a number of "build mono on Windows" discussions over the years and various attempts at improving it. Breaking the discussion into two pieces:
Release/Install/CI for Windows This was done with cygwin and was packaged by an additional installer step. The installer step was never very transparent so I can't comment on that. As for cygwin, the main issues were: - it's an amalgam of tools, which constantly update. There was never an easy way to duplicate a working setup from one machine to the next - given the size and complexity of the mono build and tests, it was generally not robust. Especially for continuous and automated usage - it was slow. Slow as in hours on Windows vs minutes on Linux Developing on Windows As for actually developing mono on Windows, the main issue was that you could not easily use Visual Studio to develop mono. The VS support for the runtime was put together long ago as a way to develop/debug, but it still required the full cygwin build to configure everything, build the class libraries, and run the tests. Even if one was brave enough to work in this setup, iteration time was slow (see above). Miguel and others made efforts to build everything using MSBuild but nothing quite materialized for a variety of reasons. All that to say, if you just want to get the Windows support back to where it was a few years ago via cygwin it can probably be done in a few developer weeks. If you actually want to improve the Windows development story, allowing for actual development and usage of Windows tools like Visual Studio it's much more work. I'd love for the latter to happen, but it's would take a lot of effort and coordination. Effort like improving xbuild where needed if msbuild is the build mechanism of choice. Coordination like making sure any work done didn't harm other platforms. - Jonathan On Thu, Oct 16, 2014 at 2:16 PM, Alex J Lennon < ajlen...@dynamicdevices.co.uk> wrote: > > On 16/10/2014 16:58, Bryan Crotaz wrote: > > What's the estimation of effort required to get mono buildable in > > windows and debuggable in VS? 6 man months? 18 man months? > > > > I don't have time to donate but I'd be happy to put some money in a > > pot with some of you to hire someone to work on this full time.
