From 3917a5e3c4b7784bf535eafb25e0a47662c0978a Mon Sep 17 00:00:00 2001 From: aszlig Date: Tue, 17 Jul 2018 02:59:32 +0200 Subject: monogame-patcher: Switch to MSBuild I really would have preferred a simple Makefile, but with that we can't use buildDotnetPackage and we also need to take care of butchering the dependencies manually. So I moved everything to src/ and added a csproj file to clean up most of the cruft and just use buildDotnetPackage with minimal attributes. In addition to that I also added assembly info, so that the command line help will show the proper author name, copyright, yaddayadda...
