Build ASP.NET Core Web App and deploy as Azure Web App on Containers

Azure Web Apps or Azure App Service Web Apps or simply Azure Websites is a PaaS service from Microsoft Azure which can be used to host web apps or APIs build using a variety of programming languages like ASP.NET, ASP.NET Core, Java, Ruby, PHP etc. It is also optimized for hosting web applications and containers, in case the SDK version required is not already supported by Web Apps. Rather than using ACS (Azure Container Services) and AKS (Azure Kubernetes Service), Azure Web Apps are more suitable for deploying long running containers. Also they become more affordable in terms of pricing as compared to the ACS and AKS. In this post, we’ll discuss how to create a very basic ASP.NET Core App and then deploy it as a container on Azure Web App.  Continue reading “Build ASP.NET Core Web App and deploy as Azure Web App on Containers”

Dotnet Core 2.0 build fails with Error MSB4062: The “GetDotNetHost” task could not be loaded from the assembly

We were recently observing this issue with one of the new source code repositories for a solution that was written in .NET Core 2.0. The source code was coded using Visual Studio and it was working fine on the developers machine. However, when building it using dotnet core publish task, it kept failing with below error:

T12:47:54.2728059Z C:\Windows\ServiceProfiles\NetworkService.nuget\packages\microsoft.aspnetcore.mvc.razor.viewcompilation\2.0.4\build\netstandard2.0\Microsoft.AspNetCore.Mvc.Razor.ViewCompilation.targets(45,5): error MSB4062: The “GetDotNetHost” task could not be loaded from the assembly C:\Windows\ServiceProfiles\NetworkService.nuget\packages\microsoft.aspnetcore.mvc.razor.viewcompilation\2.0.4\build\netstandard2.0\Microsoft.AspNetCore.Mvc.Razor.ViewCompilation.Tasks.dll.

Remove Docker Containers, Images, Volumes and Networks

Containerization has solved many issues related to traditional IT software. Docker and containers are almost synonymous as Docker makes it easy to wrap your applications and services in containers so you can run them anywhere. However as you work with Docker, you accumulate an excessive number of unused images, containers, and data volumes that clutter the output and consume disk space. Overtime it becomes necessary to clean up the clutter to claim disk space back and also prevent from disk getting full.

Fortunately, Docker has also certain inbuilt commands to clean up the system from the command line itself. This blog post aims to cover some of those commands that are useful for freeing disk space and keeping the system organized by removing unused Docker images, containers and volumes.

Change default and compare branch in VSTS

Part of the source code management is to be able to quickly determine the difference between your branch and the main development branch. Usually this happens to be the master but this can quickly change if you are following feature based development or trunk based development. VSTS has the concept of the compare branch where it would provide the number of commits ahead or behind data for all other branches. This helps one in quickly determining the related information by just taking a glance at the branch page. Continue reading “Change default and compare branch in VSTS”
