[PostEvent] CodeCamp Timisoara

I have been a presenter and participant at CodeCamp Timisoara. There are a lot of tracks with good information!

As a participant , I can mention:

Things you did not know about C# and .NET – with Marius Bancila
CALMS in DevOps – with Adrian Suteu
Making E2E tests great again using Cypress – with Omri Ben Ari

My presentation was about Angular and .NET Core Everywhere and you can find the source code at

[PostEvent] HackTalks 2019

I have been a presenter and participant at #HackTalks Timisoara. I have seen lots of interesting people that do great stuff. Also lots of programmers interested of how to do better programming. It is a good vibe and lots of knowledge sharing.

As a participant , I can mention: : Container Orchestration in the cloud for oncology  – data science and programming together for the greater good : Platform revolution in mobility –  very informative and opinionated : How to #model and #visualize complex conditional logic using a graph that describes a finite state machine in a highly flexible and data-driven way – nice way in JavaScript to describe logic flow with data .


My presentation was about Angular and .NET Core Everywhere and you can find the source code at

7 Steps from (Angular) WebApplication to Windows Store

I have deployed fairly easy the .NET Core Alphabet applcation to Windows Store . Supposing that you already have registered the name of the application to the windows store ( )

Those are the steps:

1. Compile the Angular Application ( with ng build –prod –build-optimizer  )

2. Create a new WinJS App for Universal Windows

3. Copy the results ( index.html and js )from the point 1 to a dist folder

4. Save the files with BOM ( either from VS, Save as, then save with encoding, either using dos2unix –m  <namefile>

5. Modify the main.js by adding : window.location.href=’dist/index.html’;    

6. Modify the Visual Assets to the images of your application

7. Right click the application, Store => Create App Package . And deploy to the store

As a Proof of concept, see 

Also, all the source code it is at ( and you may want to contribute, right?)

.NET Core Alphabet

What I wanted is a simple application ( Web, Mobile, Desktop) that can list , alphabetically, the .NET Core keywords. What is the purpose?

  1. For interviews – suppose you want to test the people knowledge in C#. You start the application( again: Desktop or Web or Mobile) and let the candidate choose a letter. Then you see the keywords for this letter and ask the candidate to explain some of the keywords
  2. For remembering features: there are so many features in .NET language ( ) that for a programmer it is good to know – or to revisit – the features that are in the language.
  3. For contest within programmers  – like the interviews, but for the passionate programmers that want to have an easy way to decide the one with the best memory
  4. Maybe other uses that I do not know  ? Please share in comments

Now with the realization: What I want is the simple application, that has inside the database with keywords and links and any others. From this database, the code sources for the data will be generated and the application(s) will be generated. Also, data should be publicly available to profit from the crowd power –anyone that want to add something can add.

stankins.console execute -o ReceiveRestFromFile -a primaryData/netCoreAlphabet.json -o SenderToTypeScript -a “” -o TransformerConcatenateOutputString -a a.ts -o SenderOutputToFolder -a $(Build.ArtifactStagingDirectory)/data/ -a false

stankins.console execute -o ReceiveRestFromFile -a primaryData/netCoreAlphabet.json -o SenderToRazorFromFile -a primaryData/markdown.txt -o TransformerConcatenateOutputString -a -o SenderOutputToFolder -a $(Build.ArtifactStagingDirectory)/data/ -a false

And to complete all those, it will be put in an AzureDevops pipeline

Identify version for application and components for Backend(.NET Core) and FrontEnd(Angular)–part 3- FrontEnd

Part1 : Introduction and Concepts

Part 2: Obtaining BackEnd Components Version

Part 3: Obtaining FrontEnd Component Version and Final Library

Live Demo 

NPM component
Copy paste NET code

Identifying the version of Angular components that we are using is a bit tricky. The package.json is having, by default, components using version “greater than”. More than that , after AOT compiling it remains no evidence of the original software used. However, there is a helper  npm-shrinkwrap : this will generate a npm-shrinkwrap.json file that fixes the versioning.

So the second part is to request the .NET version and the npm-shrinkwrap.json  file content with Angular front-end

For this we have a class that takes , by Dependency Injection, the HTTP Client and request versions from .NET Core and Angular:


export class VersionsNetcoreAngularService {

constructor(private http: HttpClient) {

const self = this;


public FVS(): Observable<FileVersionInfo[]> {

console.log('get fvs');

return this.http.get<FileVersionInfo[]>('api/Utils/GetVersions');


public FVSAngular(): Observable<FVSAng[]> {

console.log('get fvs angular');

return this.http.get('npm-shrinkwrap.json').pipe


switchMap(data => {

const ret = data as PackageJSONVersion ;

const d = ret.dependencies;

const arr = new Array<FVSAng>();

let f = new FVSAng(); =;

f.fileVersion = ret.version;


for (const key of Array.from( Object.keys(d)) ) {

const dep = d[key] as Dependency;

if ( {



f = new FVSAng();

f.fileVersion = dep.version; = key;



return of(arr);




The rest is history – just display the version in a HTML GUI.

In our days recognizing fast the version of the software you deploy it is important ( very important , if you do not have a continuum upgrade strategy – like Chrome does or in my days , using Click Once ). More, you should be able to recognize what components you are using in the software.

This was very interesting for me ( see  and ). However, this is not about how to version the application – but how to display the version for BackEnd and FrontEnd components.

So – we need a front-end HTML page ( or WPF, or WinForm or other front-end ) and 2 informations  : 1 for the components for the backend and one for the components for the front end .

I have made such a component – it is made for Angular and .NET Core. It can be adapted very easy for all others , by transforming the  Angular library to a WebComponent library and the WEB API .NET Core into node.js  HTTP Rest.

You will see the version of .NET Components and Angular Components that we are using.

.NET Core And Angular at CodeCamp Bucuresti

I have presented on Saturday at a technical talk about how to make a fast POC that can run on Web, Desktop and Mobile , The presentation will show a clear example of code that is necessary for that ( code at  ).

You can see working demo without CORS at , with CORS at and a Mobile app at

It was a good opportunity to learn something new at the conference – many good technical tracks and old friends that is an opportunity to see again.

Literary awards–part 5 – interactive

Part 5:


I was wandering how to make more attractive the application – and also gain some interactivity. I was thinking of the possibility  to can say what authors / books did you have read – and make some charts from it.

And here was the principal problem: how, between 2 versions of the data, to remember the authors read ? How to make the authros the same between the various awards ?

Turns out it is not so complicated – the only thing is to not version the “read” database .

So I turn out with just a database per table : one for Nobel, one for Booker, one for Bill Gates books, one for my books, one for reading list and one for all authors. Not a good thing, but this happens when you want to keep the database into the browser and updatable…

The publishing part is the tricky one. I wanted Web and Mobile ( could someone help me with the Windows/Linux part  ? )

Github let’s you have the gh-pages  as an website – see .

What this means in practice ? Menas that , if you deploy the Angular AOT to the gh-pages ( ) , then it should be visible to this url :

There is also a plugin, angular-cli-ghpages , that does this for you: takes the dist folder ( resulting from AOT Angular build ) and put in gh-pages. You can see the result at

For Mobile Android I just install the Cordova, copy the dist folder into Cordova and modify the start page in order to point to the Angular results.

But how can I compile Cordova into an Android application ? Turns out that there is a site – – that takes your code ( not only from GitHub, but for free app it is free  ) and compiles it – and it gives you back the apk. Also , it can sign the application – something that Google Play requires. ( For this, I have had some problems with generating keys:

“C:\Program Files\Java\jdk1.8.0_171\bin\keytool.exe” -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks
“C:\Program Files\Java\jdk1.8.0_171\bin\keytool.exe” -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks


You can find the Google Play application at
