dotnet

Hi, has anyone worked on adding dotnet? It looks quite complex as 
a first
project, especially as it requires going through the build in 
detail to make
sure there's no telemetry or other unwanted steps in the process.

If (and it's unlikely) I start working on this, is a good place to 
start the nix
expressions? Is it considered good or bad to look at those? And do 
you attribute
nix in such case?

Hi!

I did and it's a mssive endeavor indeed!

Last time I checked, Nix fetched the prebuilt binaries from NuGet, so we
should not do that.

Steps (off the top of my head):

- Package Mono 5 and Mono 6.  I've already done it, it just needs a
review.  This is the easy part.

- Package msbuild.  This is possibly hard.  I could not figure out a way
to bootstrap msbuild.  The upstream way to build msbuild is to use
prebuilt packages from NuGet.  If we want to build those, we need
msbuild... :(

- Make a mono-build-system that leverages msbuild.  This should not be
too hard.

- Package dotnet: I I recall correctly, it has manay dependencies, but
  one we have a mono-build-system it should not be too hard.

Cheers!

I see mono has a fork of msbuild which might be the way to go:

The readme says we need dotnet to build msbuild.

On the other hand, there is this tag:

https://github.com/mono/msbuild/releases/tag/0.08

So maybe it's bootstrappable after all.

Looks like it already tries to use this in the build, but 
something goes wrong
here at least. Haven't spent any time debugging it
