Azure Bastion - How to connect natively from Windows
If you ever used the web based client for Azure Bastion service, you would have realized that you can't really limited on what you can do and is not the same as RDP (mstsc). There is a way to connect natively to Azure Bastion service if you used the Standard SKU. The official documentation is at https://learn.microsoft.com/en-us/azure/bastion/native-client#connect-windows. The PowerShell script that will come handy is below.
az login
az account set --subscription "<<your subscription id>>"
#Launch RDP
az network bastion rdp --name "<<name of your bastion resource>>" --resource-group "<<resource group name>>" --target-resource-id "/subscriptions/<<subscription id>>/resourceGroups/<<resource group name>>/providers/Microsoft.Compute/virtualMachines/<<Virtual machine name>>"

Azure Logic App - Send Email connector - Multiple TO addresses
When using Azure Logic App connector for Azure Communication Service, you no longer can have multiple email addresses in the TO parameter. That action has been deprecated. See https://learn.microsoft.com/en-us/connectors/acsemail/#send-email-(preview)---deprecated-%5bdeprecated%5d. Instead, use the additional CC and BCC parameters. See https://learn.microsoft.com/en-us/connectors/acsemail/#send-email.

Azure Email Communication Service error - "Requested message could not be located. Couldn't find a record with the messageID"
When using Azure Email Communication service, you may run into this error - "Requested message could not be located. Couldn't find a record with the messageID". This generally is not an issue. What seems to be happening is that a getstatus call is being made almost about the same time a send call is being made. The recommendation is to write your own polling logic. See https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/email/send-email-advanced/manually-poll-for-email-status?tabs=connection-string

Uploading large files using Azure Storage REST API
When uploading files that are over 250 MB to Azure storage using the Azure Blob REST API will require you to break the file into multiple blocks that can be upto 100 MB. Use the Put Block operation to write each of the blocks to the storage. Then use the Put Block List operation to write a blob that specifies the list of block IDs that make up the blob.

Azure App Gateway with Certificate in Key Vault
It is common practice to utilize the Azure App Gateway for your web apps. SSL traffic would terminate at the gateway in this scenario. Wouldn't it be nice if you didn't have to worry about renewing your SSL certificate manually. You can do that by using the App Service Certificates and storing them in a Key Vault. The only problem is that as of the writing of this post (Feb 2024), the Azure Portal does not support App Gateway (Standard V2 tier) reading certificates from the Key Vault. According to this document https://learn.microsoft.com/en-us/azure/application-gateway/key-vault-certs#supported-certificates, this can only be accomplished via "non-portal resources like PowerShell, the Azure CLI, APIs, and Azure Resource Manager templates (ARM templates)".
The alternative is to export the certificate and manually import the PFX file into the Key Vault. You will have to remember to do this when you renew the certificate.
Hopefully this feature will be added to the Azure Portal soon.

cUrl on Powershell
It is sometimes handy to run curl commands from PowerShell.
Couple things you need to watch out for -
1) The curl command is aliased to Invoke-WebRequest. If you really want use curl natively, then run this command in your PowerShell window first.
remove-item alias:curl
2) If you are POSTing or PUTing raw JSON in the body, then it helps to store the raw json in a file and passing it as a parameter via the -T option. Below is an example
curl --location --request PUT 'https://

Getting unstuck from Azure MFA caching 500121
If you switched phones, you most likely are stuck with the 500121 error code. We were able to resolve this by going to https://entra.microsoft.com and changing the authentication method for the user in question. We had to do this for every tenant.

AI Use case for sentiment analysis
A therapist receives a sentiment analysis report for a patient prior to the scheduled appointment since the last visit. The therapist no longer has to ask, "how have you been feeling since we spoke last".
Data Driven Relationship
This is a prediction for one of the ways AI is going to be used. A wife says to her husband, "you have been grumpy all week". The husband replies, "no I have not been". Wife says, "I ran a sentiment analysis on your emails, text messages and online posts for the week. The AI engine said that you were grumpy with a 90% confidence".
