Using Blob Triggers
Learn how to implement Blob storage bindings in Azure Functions.
Functions can be bound to Azure Blob Storage, which is a type of storage that allows us to store any unstructured data, such as files. We can use Azure Functions both to write data into the blob storage and read the data from it. In this lesson, we will cover both of these functionalities. We will do so with the aid of the following interactive playground:
<Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>net6.0</TargetFramework> <AzureFunctionsVersion>v4</AzureFunctionsVersion> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.OpenApi" Version="1.0.0" /> <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.Storage" Version="4.0.5" /> <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.1.1" /> </ItemGroup> <ItemGroup> <None Update="host.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </None> <None Update="local.settings.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> <CopyToPublishDirectory>Never</CopyToPublishDirectory> </None> </ItemGroup> </Project>

Adding the required dependencies
Before we can use Azure Blob Storage bindings in a function, we need to add the Microsoft.Azure.WebJobs.Extensions.Storage
NuGet package. We do so in line 8 of the AzureFunctionApp.csproj
file.
Note: Both Blob Storage and Queue Storage use Azure ...
