Installing SQL Server Express LocalDB in a GitHub Workflow

In this post, let's see how you can install SQL Server Express LocalDB in GitHub Workflows. This is useful when you want to run integration tests in a Workflow. 

Technically you can use this approach anywhere as long as the Agent is Windows, as this is just a set of PowerShell commands.

name: Build and deploy
 
on:
  push:
    branches:
      - main
  workflow_dispatch:
 
jobs:
  build:
    runs-on: windows-latest
 
    steps:
      - uses: actions/checkout@v2
 
      - ...
 
      - name: Install MSSQLLocalDB
        run: |
            Import-Module BitsTransfer
            Start-BitsTransfer `
               -Source https://download.microsoft.com/download/3/8/d/38de7036-2433-4207-8eae-06e247e17b25/SqlLocalDB.msi `
               -Destination SqlLocalDB.msi
            Start-Process `
               -FilePath "SqlLocalDB.msi" `
               -ArgumentList "/qn", "/norestart", "/l*v SqlLocalDBInstall.log", "IACCEPTSQLLOCALDBLICENSETERMS=YES"; `
               -Wait
            sqlcmd -l 60 -S "(LocalDb)\MSSQLLocalDB" -Q "SELECT @@VERSION;"

First, we are importing the BITS (Background Intelligent Transfer Management) module, and downloading the  SqlLocalDB.msi. Then we are doing a silent install and the last command is to test the connectivity to the instance.

The specified link for SqlLocalDB.msi is for SQL Server 2022. If you want to use SQL Server 2019, you can this link: https://download.microsoft.com/download/7/c/1/7c14e92e-bdcb-4f89-b7cf-93543e7112d1/SqlLocalDB.msi

Hope this helps.

Happy Coding.

C# 12.0 Preview: Access Instance Members within nameof

In this post, let's go through a new feature that's coming with C# 12.0. With this feature, you can access instance members within nameof.

To try this feature out, make sure you have the latest version of .NET SDK (>= 8.0.0-preview.6) installed and the <LangVersion> is set to preview.

<Project Sdk="Microsoft.NET.Sdk">
 
  <PropertyGroup>
    ...
    <LangVersion>preview</LangVersion>
  </PropertyGroup>
 
</Project>

Let's consider the following example.

using System.ComponentModel;
 
Console.WriteLine(nameof(NameOfHelper.StaticInteger.MinValue));
 
internal class NameOfHelper
{
    public string MyString { get; } = "SomeValue";
 
    public static int StaticInteger;

    public string NameOfLength { get; } = nameof(MyString.Length);
 
    [Description($"Returns {nameof(MyString.Length)} of given String")]
    public int StringLength(string s) => s.Length;
}

With the above code, if we use a C# <LangVersion> prior to 12.0, we will get compile errors when using these nameof expressions. Because we are using nameof to access instance members.

But with C# 12.0, it would build just build fine.

nameof()

Azure PowerShell: Check Directory Exists in Azure File Share

In this post, let's see how to check whether a Directory exists in Azure File Share using Azure PowerShell.

I am assuming you have connected to Azure with an authenticated account and have chosen the subscription in which your storage account resides by running the following commands.

Connect-AzAccount
Set-AzContext -Subscription "<SubscriptionId>"

Now first let's get a reference to the File Share.

$ResourceGroup = "<ResourceGroup>"
$StorageAccountName = "<StorageAccountName>"
$StorageFileShareName = "<StorageFileShareName>"
 
# Get Storage Account Key
$storageAccountKey = (Get-AzStorageAccountKey `
    -ResourceGroupName $ResourceGroup `
    -AccountName $StorageAccountName).Value[0]
 
# Set AzStorageContext
$storageContext = New-AzStorageContext `
    -StorageAccountName $StorageAccountName `
    -StorageAccountKey $storageAccountKey
 
# Get the FileShare
$storageFileShare = Get-AzStorageShare `
    -Name $StorageFileShareName `
    -Context $storageContext

Here Get-AzStorageShare cmdlet returns an AzureStorageFileShare. On that, we have this nice ShareClient property. And we can use that for basically all types of operations. In this case, we need to check whether a Directory exists, so we can do something like below.

if ($storageFileShare.ShareClient.GetRootDirectoryClient().GetSubdirectoryClient("parent-directory").Exists().Value)
{
    # Directory Exists
} else {
    # Directory does not exist
}

Here I am getting to the root of the File Share, getting to the directory of my choice, and checking whether it exists. You can even pass nested paths for the directoryName, something like "parent-directory/child-directory".

This is really neat.

Hope this helps.

Happy Coding.

Connecting to Azure Cache for Redis Instance from RedisInsight

In this post, let's see how we can connect to Azure Cache for Redis Instance from RedisInsight. RedisInsight is a free tool that provides an intuitive and efficient UI for Redis and Redis Stack and supports CLI interaction in a fully-featured desktop UI client.

RedisInsight

In Azure, I have created an Azure Cache for Redis Instance (with a Public Endpoint for simplicity) and copied the connecting string which is as follows.

<my-instance-name>.redis.cache.windows.net:6380,password=<some-password>,ssl=True,abortConnect=False

Now let's start.

The first step is, of course, from RedisInsight click on ADD REDIS DATABASE. And then fill in the wizard as follows.

Configure Database Connection

You need to fill up the following,

• Host
• Port
• Database Alias (this can be anything)
• Password
• Use TLS

And then do a Test Connection. It should come up as follows.

Test Connection

After verifying the connection, click on Add Redis Database.

My Redis databases

Once it's added, click on the database. Now you can easily visualize the data in your Redis Database as well as you have a CLI at your disposal.

Data Visualizer & CLI

Hope this helps.
