Registers TableServiceClient as a singleton in the DI container for connecting to Azure Table storage. Enables corresponding health check, logging and telemetry.
An Azure storage account or Azure Cosmos DB database with Azure Table API specified. - create a storage account
Install the package
Install the .NET Aspire Azure Table storage library with NuGet:
dotnet add package Aspire.Azure.Data.Tables
Usage example
In the Program.cs file of your project, call the AddAzureTableClient extension method to register a TableServiceClient for use via the dependency injection container. The method takes a connection name parameter.
builder.AddAzureTableClient("tables");
You can then retrieve the TableServiceClient instance using dependency injection. For example, to retrieve the client from a Web API controller:
The .NET Aspire Azure Table storage library provides multiple options to configure the Azure Table connection based on the requirements and conventions of your project. Note that either a ServiceUri or a ConnectionString is a required to be supplied.
Use a connection string
When using a connection string from the configuration section, you can provide the name of the connection string when calling :
And then the connection information will be retrieved from the ConnectionStrings configuration section. Two connection formats are supported:
Service URI
The recommended approach is to use a ServiceUri, which works with the AzureDataTablesSettings.Credential property to establish a connection. If no credential is configured, the DefaultAzureCredential is used.
The Azure Table storage library supports Microsoft.Extensions.Configuration. It loads the AzureDataTablesSettings and TableClientOptions from configuration by using the Aspire:Azure:Data:Tables key. Example appsettings.json that configures some of the options:
You can also pass the Action<AzureDataTablesSettings> configureSettings delegate to set up some or all the options inline, for example to disable health checks from code:
You can also setup the TableClientOptions using the optional Action<IAzureClientBuilder<TableServiceClient, TableClientOptions>> configureClientBuilder parameter of the AddAzureTableClient method. For example, to set the first part of "User-Agent" headers for all requests issues by this client:
In your AppHost project, install the Aspire Azure Storage Hosting library with NuGet:
dotnet add package Aspire.Hosting.Azure.Storage
Then, in the Program.cs file of AppHost, add a Table Storage connection and consume the connection using the following methods:
var tables = builder.ExecutionContext.IsPublishMode
? builder.AddAzureStorage("storage").AddTables("tables")
: builder.AddConnectionString("tables");
var myService = builder.AddProject<Projects.MyService>()
.WithReference(tables);
The AddTables method will add an Azure Storage table resource to the builder. Or AddConnectionString can be used to read the connection information from the AppHost's configuration (for example, from "user secrets") under the ConnectionStrings:tables config key. The WithReference method passes that connection information into a connection string named tables in the MyService project. In the Program.cs file of MyService, the connection can be consumed using:
