How to configure runtime stack for app service in bicep script to create appservice in windows os

I am able to create appservice but run time stack is not reflecting.

I want the runtime stack of web appservice to be Node - ~18 and runtime stack of webapp-api appservice as Dotnetcore

param location string = resourceGroup().location

resource appserviceplan 'Microsoft.Web/serverfarms@2022-09-01' = {
  name: 'appserviceplan1'
  location: location
  sku: {
    name: 'S1'
    capacity: 1
  }
}

resource appserviceapi 'Microsoft.Web/sites@2022-09-01' = {
  name: 'appservice-webapp-api1'
  location: location
  properties: {
    serverFarmId: resourceId('Microsoft.Web/serverfarms', appserviceplan.name)
    siteConfig: {
      appSettings: [
        {
          name: 'WEBSITE_NODE_DEFAULT_VERSION'
          value: '18.14.0'
        }
      ]
    }
  }
  dependsOn: [
    appserviceplan
  ]
}

resource appservice 'Microsoft.Web/sites@2022-09-01' = {
  name: 'appservice-webappservice-app1'
  location: location
  properties: {
    serverFarmId: resourceId('Microsoft.Web/serverfarms', appserviceplan.name)
    siteConfig: {
      appSettings: [
        {
          name: 'CURRENT_STACK'
          value: 'Node.js - ~18'
        }
      ]
    }
  }
  dependsOn: [
    appserviceapi
  ]
}

Hi @SISIRA SARU ABEY

To configure the runtime stack for an App Service in a Bicep script, you can use the siteConfig property of the Microsoft.Web/sites resource Here’s how you can set the runtime stack for your web app service to Node.js - ~18 and your webapp-api app service to Dotnetcore:

resource appserviceplan 'Microsoft.Web/serverfarms@2022-09-01' = {
  name: 'appserviceplan1'
  location: location
  sku: {
    name: 'S1'
    capacity: 1
  }
}

resource appserviceapi 'Microsoft.Web/sites@2022-09-01' = {
  name: 'appservice-webapp-api1'
  location: location
  properties: {
    serverFarmId: resourceId('Microsoft.Web/serverfarms', appserviceplan.name)
    siteConfig: {
      appSettings: [
        {
          name: 'FUNCTIONS_WORKER_RUNTIME'
          value: 'dotnet'
        }
      ]
    }
  }
  dependsOn: [
    appserviceplan
  ]
}

resource appservice 'Microsoft.Web/sites@2022-09-01' = {
  name: 'appservice-webappservice-app1'
  location: location
  properties: {
    serverFarmId: resourceId('Microsoft.Web/serverfarms', appserviceplan.name)
    siteConfig: {
      appSettings: [
        {
          name: 'WEBSITE_NODE_DEFAULT_VERSION'
          value: '~18'
        }
      ]
    }
  }
  dependsOn: [
    appserviceapi
  ]
}

In this example, its set the siteConfig property of each Microsoft.Web/sites resource to include an appSettings array with a single object that specifies the desired runtime stack. For the web app service, we set the WEBSITE_NODE_DEFAULT_VERSION to ~18, and for the webapp-api app service, we set the FUNCTIONS_WORKER_RUNTIME to dotnet.
