While we are working on some new exciting stuff we continue improving things to make your AppVeyor experience even more smooth and streamlined. One of those recent improvements is a new build worker provisioning engine. Every build in AppVeyor runs on a dedicated virtual machine hosted in Microsoft Azure (yes, now it’s called “Microsoft Azure”). Azure is a great platform - their VMs are considerably faster than competitors’ and creation of a new VM is a blast (usually around 3 minutes). Simplified build flow is the following:
We were creating a new VM and then passing build details and starting Build Agent service through PowerShell remoting. That approach had a number of disadvantages:
The new provisioning mechanism works “inside out”, i.e. Build Agent is started on VM boot and is “listening” for incoming command from AppVeyor using Web Sockets.
This new approach gives a number of benefits:
We also optimized worker “master” image (VHD) itself to make sure only minimum set of services is enabled to boot fast, eliminate lags and free more memory for your builds. Of course, you can still configure required services such as IIS and SQL Server databases.
Oh, and we introduced Windows Server 2012 R2 image which has almost identical configuration to Windows Server 2012 (except it doesn’t have VS 2010 installed).

When deploying web application to different environments you don’t want to re-build application package every time with different configurations, but you want to deploy the same package (artifact) with some environment-specific settings configured during deployment. When using Web Deploy the problem can be easily solved by Web Deploy parametrization.
Most common use cases for Web Deploy parametrization is updating node/attribute value in XML files or replacing a token in text files, for example:
To enable Web Deploy parametrization add
parameters.xml file in the root of your web application.
Parameters.xml contains the list of parameters required (or supported) by your Web Deploy package. In the example below we introduce two parameters - one to update path to log file in
appSettings section of
web.config and another one to set database name in SQL script.
Parameter element describes the name, default value and the places where and how this parameter must be applied.
Parameters.xml for our example:
<?xml version="1.0" encoding="utf-8" ?> <parameters> <parameter name="LogsPath" defaultValue="logs"> <parameterEntry kind="XmlFile" scope="\\web.config$" match="/configuration/appSettings/add[@key='LogsPath']/@value" /> </parameter> <parameter name="DatabaseName"> <parameterEntry kind="TextFile" scope="\\Database\\install_db.sql$" match="@@database_name@@" /> </parameter>
When Web Deploy package is built you can open it in the explorer and see
parameters.xml in the root:
parameters.xml combines your custom parameters and system ones such as
IIS Web Application Name. You don’t have to set
IIS Web Application Name parameter explicitly - AppVeyor does that for you.
Read more about defining parameters: https://technet.microsoft.com/en-us/library/dd569084(v=ws.10).aspx
Web Deploy provider in AppVeyor analyzes Web Deploy package and looks into environment variables to set parameter values with matching names.
When promoting specific build from Environment page you set variables on environment settings page:
When deploying during the build session environment variables are used instead. You can set build environment variables on Environment tab of project settings,
appveyor.yml or programmatically during the build.
Variables defined during the build override those ones defined on Environment level.
Web Deploy parametrization is supported by Deployment Agent too when deploying from Web Deploy package.

I’m thrilled to announce that AppVeyor 2.0 officially goes Live and with the new aggressive pricing!
After being almost two months in private and then public beta we finally upgraded production environment to AppVeyor 2.0 and developers truly love it!
Let me quickly recap what new features AppVeyor 2.0 brings to you:
AppVeyor 2.0 moved from shared build farm to dedicated build machines. With that change it was obvious the current pricing scheme must be adjusted to justify new architecture. We received a signal from our customers that new plans felt pricey and not affordable for individual developers and small teams. This was not exactly our intention. We don’t want you to go through nightmare of installing TeamCity or Jenkins on Azure VM! :)
We want AppVeyor to be a great tool in the hands of every Windows developer! We listened to you and we revisited our plans before going Live to make sure AppVeyor pricing works for everyone.
|Unlimited public repositories||10 private repositories||Unlimited private repositories||Unlimited private repositories|
|1 concurrent job||1 concurrent job||2 concurrent jobs||4+ concurrent jobs|
|Forums support||Email support||Email support||Priority technical support|

AppVeyor is Continuous Integration service for Windows developers to securely build and test code in parallel and deploy successful bits to on-premise or cloud environments.
In this tutorial we’ll guide you through the process of setting up a continuous delivery process for sample Azure Cloud Service (Azure CS) application starting from a code push to a repository and finishing with deployment of successful build to Azure.
On Saturday, March 29, 2014 Global Windows Azure Bootcamp (GWAB) will take place in 141 locations across the globe. If you are not registered yet go find a location near you and do that. AppVeyor CI is one of the sponsors of this event and during that time we will be giving 2 free months with the purchase of any AppVeyor plan to all GWAB attendees.
AppVeyor CI has tight relationship with Windows Azure platform. First of all, AppVeyor is built for Azure and it uses Azure IaaS to run your builds on dedicated virtual machines. Second, AppVeyor provides complete Continuous Delivery cycle for Azure projects, i.e. building, testing, packaging and deploying your web applications and Azure Cloud Services. GWAB training classes is a wonderful place to try AppVeyor and setup super-simple continuous integration for your lab project.
We’ve created a simple Azure Cloud Service solution created in Visual Studio 2013 and consisting of a WebRole and xUnit test projects. You can find sample project repository on GitHub.
Note, that we don’t have “NuGet Package Restore” enabled for VS solution (no .nuget folder in repository). This is not necessary in AppVeyor environment - below you’ll see how to do that.
If you don’t have AppVeyor account yet you should definitely get one! Go to https://ci.appveyor.com/signup and use “GitHub” button to sign up for Free plan which allows you building public repositories.
Click New project and select GitHub repository:
AppVeyor will automatically configure webhook for the repo to start a new build on every push.
To enable restore of NuGet packages during the build open project settings and add “nuget restore” command into before build script:
Run New build and see its progress in a real-time build console:
If you click Artifacts tab upon build completion you will see that AppVeyor automatically detected and packaged Azure Cloud Service project along with its configuration:
In just a few minutes we have a pretty decent Continuous Integration process for our Azure Cloud Service!
Now let’s deploy our “experimental” app to Windows Azure. Go to Environments and add new “Azure Cloud Service” environment:
The form requires 3 prerequisites:
Download Azure account publishing profile and open it in text editor. Copy subscription ID and Base64 encoded subscription certificate.
Now kick off new deployment of azure-cs-demo project to azure demo environment:
Select the build to deploy:
Observe the progress of deployment in the real-time console:
Azure Cloud Service package from build 1.0.2 artifacts has been deployed and you can see the results in Azure Portal:
Now after we triggered deployment manually from UI we’d like to completely automate the process and deploy during successful build. To setup deployment to azure demo environment open “Deployment” tab of project properties, add new “Environment” deployment and specify “azure demo” as environment name:
Done! Next time you push your changes into GitHub repository or start a new build on UI AppVeyor will build solution, run tests and deploy to Azure.

NuGet provides few different methods of restoring missing NuGet packages during application development on in Continuous Integration environment. In this article we’ll review these methods to find out which one to choose for using in AppVeyor CI environment.
After reading the original NuGet Package Restore article on NuGet docs web site we see that today we have three options for restoring packages:
Important note here - not before, but during MSBuild process. This is accomplished by injecting nuget.targets into build pipeline, so you end up with .nuget folder in your solution. This method works in build environment and requires consent which is EnableNuGetPackageRestore environment variable (it’s ON by default starting from NuGet 2.7 but we set it in AppVeyor environment for compatibility with previous NuGet versions). Starting from NuGet 2.7 this method is considered as obsolete as it requires additional folder with nuget.exe, nuget.targets and do not work in some scenarios (remember that chicken/egg problem with BCL packages.
This method is part of NuGet Visual Studio add-in (.vsix), heavily relies on VS events and works in interactive mode, not build environment. Excerpt from that page:
In other words, restore occurs in Visual Studio and before MSBuild process.
The method was always there, but “was improved in NuGet 2.7”. This is exactly what we need and do in AppVeyor build environment! All that you need is to put “nuget restore” command into “Install scripts” or “Before build scripts” box of your project settings:
or in appveyor.yml:
before_build: - nuget restore
Hope that helps.
