Using MSBuild tool to get code coverage and configure Azure DevOps pipelines to include code coverage results is an easy task for .NET framework based applications. Azure DevOps (formerly VSTS) contains inbuilt functionality to analyze code coverage files generated and publish results back to VSTS itself. However, it is quite a challenge to get it right and working for .NET Core 2.0 based applications. In this blog post, we’ll cover steps on how to get code coverage results for .NET Core based application using SonarQube and Azure DevOps.

Using SSL to secure incoming and outgoing traffic from your server is always recommended. When you are developing locally or testing on a server, whether it is Windows or Macintosh or some distribution of Linux like CentOS, fedora, Ubuntu etc, its easy to put the certificate in one of the local directories and then ask server to use the same. However this becomes a little bit different if you are using Containers. Since Docker is the most popular container technology, it has become almost synonymous with containers. When using containers, you can many choices:
1) Map a local volume containing certificate files to the container and then refer to it from inside container
2) Copy certificate directly inside Container during image build process and then refer to it Continue reading “Use SSL Certificates for Dotnet Core Application in Docker Containers”
.NET Core is the cross platform and open-source framework based on .NET framework. It is maintained by both Microsoft and the community at https://github.com/dotnet/core on Github. In this blog post, we’ll learn to install dotnet core on the Ubuntu. For the post’s purpose we’ll use Ubuntu 16.04 since that is latest LTS release from Ubuntu which has the support from almost all software vendors.
Register Microsoft key and feed
Before installing .NET, you’ll need to register the Microsoft key, register the product repository, and install required dependencies by running the following commands: Continue reading “Install dotnet core SDK and runtime on Ubuntu OS”
In old days (not so old, albeit like a one or two year(s) ago), we used to insert a docker environment variable like IS_DOCKER_CONTAINER using dockerfile in docker images. This was used to determine if an application is running inside a docker container or not. This helped to set certain attributes of the application like logging level and methods, modify certain environmental settings etc and helped controlling behavior of the application. It can also be useful in other situations like to determine whether you want to run selenium tests or not (as selenium web drivers would not be available inside docker container) to run as part of the integration testing.

After making some changes to the build definition of one of the dotnet core repositories, we started observing this error with the SonarQube tasks inside the build definition in VSTS:
When we checked the complete logs, we observed below issue:
This is one of the errors that we encountered in the ASP.NET core build process. To this date, this issue can be easily reproduced by creating a ASP.NET core web api process and repeating ‘dotnet publish’ command with using an output directory and parameter –output. However, it does not happen with the simple console applications.
When we try to publish files, it creates nested multiple output directories like below: Continue reading “Publishing Dotnet Core creates multiples nested directories”
Microsoft has invested billions in Azure to drive technology and also hired best of the minds on this planet. From last few months, Azure has been launching new container-focused products and services on a regular basis. One of these products is Azure Container Instances. It acts as a bridge between platform as a service and infrastructure as a service architecture. Perhaps it would be okay to call this service as “Container as a Service”. Azure Container Instances (ACI) allows to rapidly create and launch containerized applications, without any overhead and with an easily scriptable set of commands. Designed to work Continue reading “Deploy ASP.NET Core App as Azure Containers Instances (ACI)”
