Vielen lieben Dank an alle Teilnehmer und an die Organisation der Konferenz!
Bis zum nächsten Mal
Thinktecture was at the MVP Summit 2014 ASP.NET Hackathon: after Dominick and Brock had Identity Server running on ASP.NET vNext, I took a stab at getting that code working on Linux/Ubuntu.
For this I needed to clone and build Mono as there are a couple of necessary patches which are not yet in any released Mono build (see this blog post for details).
This is a very easy thing to do on Ubuntu:
git clone git://github.com/mono/mono.git cd mono ./autogen.sh --prefix=/usr/local make sudo make install
After this executed successfully – bring … some… time! – we have the latest Mono version:
Next thing to do is bringing Kestrel as the HTTP server into the picture:
{
"webroot": "wwwroot",
"version": "1.0.0-*",
"exclude": [
"wwwroot"
],
"packExclude": [
"**.kproj",
"**.user",
"**.vspscc"
],
"dependencies": {
"Kestrel": "1.0.0-*",
"Microsoft.AspNet.Server.IIS": "1.0.0-beta1",
"Microsoft.AspNet.Owin": "1.0.0-beta1",
"Microsoft.AspNet.Diagnostics": "1.0.0-beta1",
"Microsoft.AspNet.WebApi.Owin": "5.2.2",
"Microsoft.Owin": "3.0.0",
"Thinktecture.IdentityServer.v3": "1.0.0-beta3-1",
"Thinktecture.IdentityModel.Core": "1.2.0",
"Microsoft.Owin.Security": "3.0.0",
"Microsoft.Owin.Security.Google": "3.0.0",
"Microsoft.Owin.Security.OpenIdConnect": "3.0.0"
},
"commands": {
"Kestrel": "Microsoft.AspNet.Hosting --server Kestrel --server.urls http://localhost:5005",
},
"frameworks" : {
"aspnet50" : { }
}
}
As Identity Server comes with its own Test X509 certificate it is necessary to import this cert into the Mono certificate store – like this:
certmgr -add -c -p idsrv3test -m My idsrv3test.pfx
One thing that was left to get IdSrv finally running successfully was working around a bug in the ASP.NET vNext HTTP abstractions (GitHub issue – it has already been fixed ).
Once that was sorted out – tadaa!
Hope that helps.
Yesterday I thought I would try and prove Microsoft’s promise that the new and overall cool ASP.NET vNext would run on many platforms, including Windows, MacOS X, and Linux.
My target platform for this experiment was Linux. First thing to do in this case is check out of of the myriads of Linux distros. After a bit of investigating I chose the Ubuntu-based Xubuntu. Very slick!
After installing Xubunutu (it took only a few minutes, literally) in a Parallels VM on my MacBook Pro, I went ahead to get Mono running. Turns out the the most reliable way to get recent versions of Mono running on stable Linux distros these days is to suck down the source code and compile it.
So here we go with some simple steps (may take a couple of minutes to get through, though):
sudo apt-get install build-essential wget http://download.mono-project.com/sources/mono/mono-3.8.0.tar.bz2 tar -xvf mono-3.8.0.tar.bz2 cd mono-3.8.0/ ./configure --prefix=/usr/local make sudo make install
This gives us the Mono 3.8.0 CLI:
According to the ASP.NET vNext Home repo on GitHub this should be all we need to get started with the samples. NOT. When we build the source of the samples we get a network-related exception showing up.
The issue is the certificates used for the package sources. The .NET Framework on Windows uses the Windows Certificates store to check whether to accept an SSL certificate from a remote site. In Mono, there is no Windows Certificate store, it has its own store. By default, it is empty and we need to manage the entries ourselves.
CERTMGR=/usr/local/bin/certmgr
sudo $CERTMGR -ssl -m https://go.microsoft.com
sudo $CERTMGR -ssl -m https://nugetgallery.blob.core.windows.net
sudo $CERTMGR -ssl -m https://nuget.org
sudo $CERTMGR -ssl -m https://www.myget.org/F/aspnetvnext/
mozroots --import --syncAfter these steps we should be able to build the samples from the ASP.NET vNext Home repo successfully, e.g. the HelloMvc sample.
Running kpm restore looks promising, at least:
When we then try to run the sample with k kestrel (Kestrel is the current dev web server in vNext) we get a wonderfully familiar error:
Object reference not set to an instance of an object.
Hooray!!!
After some Googling I found out that the underlying libuv (yes, that same libuv used in node.js) seems to be the problem here. A quick chat with the ASP.NET vNext team reveals it seems like this will be fixed in the future, but there are some more important things to get done by now.
Anyway, I got it finally to work by replacing libuv as suggested here:
ln -sf /usr/lib/libuv.so.11 native/darwin/universal/libuv.dylib
When I now run k kestrel again everything is fine:
By default, Kestrel runs on port 5004 – thus opening our browser of choice with http://localhost:5004 gives us the desired result:
Mission accomplished.
Thanks for listening.
Die BASTA! Spring ist rum, und wieder einmal war es super. Danke an die Organisierer und natürlich an die Teilnehmer!

Zu den Ganztages-Workshops am Montag und Freitag gibt es naturgemäß keine Folien
Für den Freitags-Workshop “End-to-End-Implementierung einer Cross-Platform Modern Business Application” gibt es hier das “laufende” GitHub-Repository, in das Ingo Rammer und ich während des Tages immer hinein ge-psuhed haben.

Viel Spaß!
