AppVeyor: A simple build server for open source projects

For LightCore 2.0 I would like to show the build state inside the GitHub repository. I could use my personal Jenkins build server on a Azure VM, because Jenkins also provides the build state, with a plug-in.

But this seems to be the right moment to play around with AppVeyor:

AppVeyor is a browser based SaaS (Software as a Service) application in the cloud. AppVeyor provides many useful features within a pretty simple, intuitive and clean UI. GitHub is completely integrated and it is really easy to create a build job for a GitHub project:

The .NET Version Manager (DNVM) is already installed and you only need to figure out which run-time is used by default. I used the build output to see the results of the "dnvm" commands. Finally I choosed the way to install the needed beta-8 with the batch scripts, every time the build starts:

dnvm update-self
dnvm install 1.0.0-beta8 -a x86 -r coreclr -OS win 
dnvm alias lccoreclr 1.0.0-beta8 -a x86 -r coreclr -OS win 
dnvm install 1.0.0-beta8 -a x86 -r clr -OS win
dnvm alias lcclr 1.0.0-beta8 -a x86 -r clr -OS win

For the builds and the tests I also used the batch command mode with the following lines:


cd LightCore 
dnvm use lccoreclr 
dnu restore 
dnu build


cd ..\LightCore.Tests 
dnvm use lccoreclr 
dnu restore 
dnx test 

Show the build state

Finally I'm able to copy a small piece of MarkDown code, which I can use in the file in the GitHub repository to show the current build state:

As you can see, it is pretty simple to use and handle AppVeyor. I'm sure I'll also use AppVeyor for my other open source project, the "SimpleObjectStore". But I need to move that library to .NET Core first. ;)
