Windows: Generate SSH Keys

Windows:  Generate SSH Keys 

There are several way to generate SSH Keys.  This example uses just ssh-keygen

ssh-keygen -t rsa -b 2048

Then you can find the generated key

C:\> cd %HomePath%/.ssh 

Reference:  https://docs.microsoft.com/en-us/azure/virtual-machines/linux/ssh-from-windows

Mac: Generate SSH to use with Github

Open Terminal and type:

$ ssh-keygen -t rsa -b 4096 -C "yourname@yourdomain.com"

Use the defaults by pressing enter..  Generic Example:

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/john.doe/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/john.doe/.ssh/id_rsa.
Your public key has been saved in /Users/john.doe/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:s/NA0e62g1zjEmAtUIi42/cEEicAGVs+fDcuAtOFlrY john.doe@doeinc.com
The key's randomart image is:
+---[RSA 4096]----+
|         .o+o+oo.|
|        o+o.+oo.=|
|       . o+.+=+++|
|        o  o++++.|
|       .S. ..*o.o|
|        o=o.o+.. |
|        o.o.+E*  |
|         ++.++ o |
|          .++.. +|

Angular 5 to 6 Upgrade Migration with Error Fixes

Angular 5 to 6 Upgrade Migration

  • Go to https://update.angular.io/ to generate steps for upgrade.
  • Switch HtpModule and Http to HttpClientModule and HttpClient
  • Make sure you're using Node 8 or later
  • Run the commands
    • ng install -g @angular/cli
    • ng install @angular/cli
    • ng update @angular/cli
    • ng update @angular/cli (Yes this was intended.  Run it twice, I think there is a bug with update).  This will cause angular-cli.json to be updated (Renamed) to angular.json and keep you from getting the error:  Local workspace file ('angular.json') could not be found.
  • ng update @angular/core
  • ng update @angular/material
  • ng update
  • ng update
  • rxjs-5-to-6-migrate -p src/tsconfig.app.json
  • Remove deprecated RxJS 6 features using rxjs-tslint auto update rules.  If you don't you'll get errors like node_modules/rxjs/BehaviorSubject.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/BehaviorSubject'.
    • npm install -g rxjs-tslint
    • npm install --save rxjs-tslint
  • Add rules to tslin.json
    • {
        "rulesDirectory": [
        "rules": {
          "rxjs-collapse-imports": true,
          "rxjs-pipeable-operators-only": true,
          "rxjs-no-static-observable-methods": true,
          "rxjs-proper-imports": true
    • Lint the project by executing
      • ./node_modules/.bin/tslint -c tslint.json -p tsconfig.json
      • If you get the error Error: Cannot find module 'typescript', run npm install -g typescript then re-run 
        • ./node_modules/.bin/tslint -c tslint.json -p tsconfig.json
  • Once you all all of your dependencies have update to RxJs, remove rxjs-compat

ASP.NET Core - Entity Framework - Code First Add-Migration - Unable to resolve service for type Microsoft.EntityFrameworkCore.Migrations.IMigrator.

Entity Framework Error:

Unable to resolve service for type 'Microsoft.EntityFrameworkCore.Migrations.IMigrator'. This is often because no database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.


Verify the connectionstring in the appsettings.json file.

  "ConnectionStrings": {
    "CustomerDb":  "Server=(localdb)\\mssqllocaldb;Database=Customer;Trusted_Connection=True;"
On Startup.cs, ConfigureService method, verify, you are correctly initializing the Context

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
            services.Configure<CookiePolicyOptions>(options =>
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;

            services.AddDbContext<AppDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("CustomerDb")));
