I'm looking to use abp.io and azure webjobs or functions to create a job scheduler for many jobs. Each job would be in a module and have its own settings for how often to run the background task. Wondering if anyone has successfully done this already?
Yes, I have done that. We have an .Net core console application created with an ABP template that does all the long-running background jobs. I struggled with it for a while but got it working. The trick was to publish the project directly into a path that the app service uses to find runnable web jobs. We are using azure DevOps where the publish configuration looks like this: --configuration $(BuildConfiguration) --self-contained -r win10-x64 --output $(Build.BinariesDirectory)/publish_output/App_Data/jobs/continuous/background-process-manager.
It is also now possible to use the ABP framework with Azure functions. This can be achieved using the isolated mode: https://learn.microsoft.com/en-us/azure/azure-functions/dotnet-isolated-process-guide. This works if you don't want to use the ABP background jobs triggered from another application. In our case, we wanted to run long-running background jobs triggered either on schedule or by our web application. Using the ABP background job structure required us to run the background process manager as a continuous web job.

We now have two applications with two differents git respositories. The first one is in ReactJS for the front and the second one is in C# (Web Api 2) for the back. When we want to deploy on Azure, we build the front and we copy the output files to the c# project (web api project). We deploy the web api application from Visual Studio in Azure thanks to the deploy menu.
It's a little bit boring and sometimes we have errors when we change by hand the parameters relative to our differents environments.
We would like to automatize all these tasks with Azure Dev Ops. Have you ever done this kind of stuff ? And how ? Sorry, if this question seems stupid but i can't find a tutorial to build when the front and the back are not in the same git repo. Thanks in advance for your help.
You can follow below steps to build and deploy your application. I can only give a general idea and steps. The main idea is to get your front and backend source code together and build them in the same pipeline. The configurations and parameters for each tasks in the build pipeline need you to specify according to your project.
Below steps is shown in classic view pipeline. Check here for yaml view pipeline
1,Sign in to your Azure DevOps organization and navigate to your project.
2,Go to Pipelines, and then select New Pipeline, and select Use the classic editor to create a pipeline without YAML at the end of the page.
3,Walk through the steps of the wizard by first selecting as the location of your source code.
4, select a source to specify where your code is located. And continue to choose a template, here i choose ASP.NET Core(.NET Framework) template.
5, Add a powershell task to the top of your pipeline(the tasks can be drag and drop to reorder) to run the git commands to clone your front react.js code into same source folder of your backend c# code.
If your code is hosted in azure repo git. You can add below scripts in your powershell task. Make sure Allow scripts to access the OAuth token is checked
cd $(Build.SourcesDirectory)
git clone "https://$env:SYSTEM_ACCESSTOKEN#dev.azure.com/{yourAzureorganizationName}/{yourProjectname}/_git/testrepo"
6, add npm install task and npm custom task to build your react.js, You need to specify the path of Working folder that contains package.json to the folder where you cloned your reactjs code in the above powershell step. you can check steps here for reference.
7, Add a copy file task before task Visual Studio build to copy the output files from building react.js to the your c# project.
8, Configure the necessary path and parameters for Visual Studio build
task and Visual Studio test task to build and test your backend c# code.
9, Add an Azure App Service deploy task at the end to deploy to azure.
You might need to add other additional tasks to build your projects. You can also move your deployment task to release pipeline.check here for more information.
There are lots of examples and learning materials that you can find online about how to create build pipeline and how to deploy your application to azure. I suggest you can follow one example to create your build pipeline for c# project and try to edit your existing pipeline to integrate your react.js project.
Here is microsoft official documents for you to check it out. Hope you find above helpful.
Here, you can find the steps to build and release two web apps (hosting web api) and the relative front developed in ReactJS. Here's our goal :
In Azure devops, we've created a pipeline using the classic editor :
We selected our git repository and this template :
After a step of creating tasks, we obtain :
We'll describe some of these tasks. For example :
/p:SkipInvalidConfigurations=true /p:DeployOnBuild=true /p:WebPublishMethod=FileSystem /p:publishUrl="$(build.artifactstagingdirectory)\appRetailLab" /p:DeployDefaultTarget=WebPublish
Once you've build the two web applications, you've to copy the front files in web applications. There're two tasks for that :
At last, you publish your artefacts in the drop directory within the build.artifactstagingdirectory :
The release :
Our release is not too difficult :
We use 4 tasks :
Replace Token is a very usefull plugin. You can replace a token (defined by a template) by a value defined in the release. We use this plugin to replace our token in the front part of our applications (js files).
To add token in our reactjs application, we use dotenv npm package.
For the web.config parameters don't forget to check XML Variable substitution in your deploy task.
That's it.
So I started to play with Google Mobile Backend Starter.
Now I want to clean this instance and anything that this starter thingy created into the project (e.g. task queues, data store, etc...)
How do we achieve this?
Is this done through some command line somewhere along the lines described in this page?
appengine-java-sdk/bin
EDIT: I should have made it clearer, I don't intend to delete the project. I just want to "clean" it and replace with my own application. Anyway, I ended up using the appengine SDK tools mentioned above (Updating and Managing a Java App). It was a long process, and tedious. It could be improved.
What I did:
Using the appengine SDK tool, downloaded the application first. It prompted me for a password. I had to create a new "App Password" entry in my Google account, since it didn't accept my "usual" Google password (e.g. GMAIL)
To clean the Scheduled Tasks, edit cron.xml so that no entries are left. A sample empty cron.xml file is shown in the documentation page. Run the update procedure of the SDK tool for cron jobs
To clean the Queues, use the same approach (queue.xml)
Clean DataStore by going to DataStore Admin page (if applicable)
Upload your new application (either thru SDK, or thru Android/Eclipse AppEngine plugin)
There will now be 2 (or more) versions of your AppEngine. If necessary, make your newly uploaded application, the default version. This is done in the Developer Console.
Check the instances as well. Remove if necessary
I have a desktop application in C# and i want to make that a window service. Is it possible to make that application as a windows service? Basically i want an app that shows gui when needed and upone minimizing it goes to system try, and it should also appear in services... For application just take an example that my application have a timer and multiline text field and its also interacting with database and its showing timely status from database so when i need to see it i can start GUI from system try?
Any kind of help would be highly appriciated. Thanks!
You will need to separate your applications. Windows Service and desktop. You will need to build API hooks into your Windows Service to allow communication from your desktop application and the service. I would recommend WCF for this.
In a nutshell, a Windows Service should not interact with the desktop. It will run in a separate session than the session you are logged into, even if you are logged in as the same account the service is running under.
It is not possible to show GUI in a windows service.
What you can do is:
a. Seperate client logic from server logic, the windows service will perform the server side operations and will expose a WCF API to the client , which will handle the GUI related issues.
b. Use an external tool like Service-O-Matic to control your winforms application as if it was a windows service. see:
http://www.kwakkelflap.com/service.html
The application(JSF+hibernate) is been deployed using the vmc commands as on the cloudfoundry site. able to see the welcome page. postgreSQl service is binded with the application but the application is not able to connect with the database.
And also viewed about the VCAP_SERVICES using java but dont know much about it rather how to create it.
Cloud Foundry uses auto-reconfiguration if you have one service (either MySQL or Postgres) bind to your application. That means you don't need to touch your code at all!
Please review the following article on our docs site:
http://docs.cloudfoundry.com/frameworks/java/spring/spring.html#using-cloud-foundry-services-in-spring-applications
If you still have issues, go ahead and upload a war file of your app and we can take a look.
I have an application that I need to deploy via ClickOnce on a web page, but I need it to only install the application and not execute it automatically after the install is complete. The user should have to manually start the application from the start menu - even after the initial install.
How do I accomplish this?
The answer is in the MSDN article How to: Disable URL Activation of ClickOnce Applications by Using the Designer.
