Prefer use of Azure Static Web App CLI (simulator)

[DuAell]

Whilst the solution given by @anthonychu is awesome, there is a new way of simulating Static Web App environment for local development : https://docs.microsoft.com/en-us/azure/static-web-apps/local-development

Install it : npm install -g @azure/static-web-apps-cli

Create a swa-cli.config.json file in the root folder and paste inside :

{
  "$schema": "https://raw.githubusercontent.com/Azure/static-web-apps-cli/main/schema/swa-cli.config.schema.json",
  "configurations": {
    "app": {
      "context": "https://localhost:7229",
      "apiLocation": "https://localhost:7071",
      "swaConfigLocation": "Client/wwwroot"
    }
  }
}

Then launch swa start from the root folder

Your Blazor app should be used from http://localhost:4280/ and will use the simulator for authentication.
