Highlights

• Extendable Params are now GA! (#19697)

  Extendable Bicep Parameter Files (enabled with the extend keyword) allows you to reuse parameters from one .bicepparam file in another .bicepparam file.

  root.bicepparam This is your main bicepparam file, which can be reused by multiple extended .bicepparam files and in multiple deployments.

  using none
  // Notice that the first line of this .bicepparam file declares `using none` which tells the compiler not to validate this against any       particular .bicep file.
  
  param namePrefix = 'Prod'

  leaf.bicepparam This is your extended bicepparam file, which will refer to one main.bicep file and one main .bicepparam file. Any parameter value in this file will override all previous values.

  using 'main.bicep'
  
  extends 'root.bicepparam'
  
  param namePrefix = 'Dev' // this will override the 'Prod' value we assign in our root.bicepparam file

• ThisNamespace and NullIfNotFound are now GA! (#19639)

  When applied to an existing resource, using the @nullIfNotFound() decorator for existing resources will return null if it doesn't exist at deployment time instead of failing.

  @nullIfNotFound()
  resource exampleResource 'Microsoft.Storage/storageAccounts@2021-04-01' existing = {
    name: 'test'
  }

  For 'ThisNamespace': this.exists() returns a bool indicating the existence of the current resource. this.existingResource() returns null if the resource does not exist and returns the full resource if the resource exists.

  resource usingThis 'Microsoft...' = {
    name: 'example'
    location: 'eastus'
    properties: {
      property1: this.exists() ? 'resource exists' : 'resource does not exist'
      property2: this.existingResource().?properties.?property2
      property3: this.existingResource().?tags
    }
  }
