Configuration

AppSettings

{
  //LiteX Azure Storage settings
  "AzureBlobConfig": {
    "AzureBlobStorageConnectionString": "--- REPLACE WITH YOUR AZURE CONNECTION STRING ---",
    "AzureBlobStorageContainerName": "--- REPLACE WITH YOUR AZURE CONTAINER NAME ---",
    "AzureBlobStorageEndPoint": "--- REPLACE WITH YOUR AZURE END POINT ---"
  }
}

Startup Configuration

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // 1. Use default configuration from appsettings.json's 'AzureBlobConfig'
        services.AddLiteXAzureBlobService();

        //OR
        // 2. Load configuration settings using options.
        services.AddLiteXAzureBlobService(option =>
        {
            //option. = "";
        });

        //OR
        // 3. Load configuration settings on your own.
        // (e.g. appsettings, database, hardcoded)
        var azureBlobConfig = new AzureBlobConfig();
        services.AddLiteXAzureBlobService(azureBlobConfig);
    }
