Fix casing of IsRefreshable in Dataset.Serialization.cs

[Arjan321]

Description

A regression occurred in the v5 release of the PowerBI SDK. The casing of various properties in DataSet are wrong.

v4:

#:property PublishAot=false

#:package Microsoft.Identity.Client@4.79.2
#:package Microsoft.PowerBI.Api@4.22.0

using Microsoft.Identity.Client;
using Microsoft.PowerBI.Api;
using Microsoft.Rest;

var clientId = Environment.GetEnvironmentVariable("POWERBI_CLIENT_ID") ?? throw new InvalidOperationException("POWERBI_CLIENT_ID environment variable is not set.");
var clientSecret = Environment.GetEnvironmentVariable("POWERBI_CLIENT_SECRET") ?? throw new InvalidOperationException("POWERBI_CLIENT_SECRET environment variable is not set.");
var tenant = Environment.GetEnvironmentVariable("POWERBI_CLIENT_TENANT") ?? throw new InvalidOperationException("POWERBI_CLIENT_TENANT environment variable is not set.");
Guid workspaceId = Environment.GetEnvironmentVariable("POWERBI_WORKSPACE_ID") is string workspaceIdString && Guid.TryParse(workspaceIdString, out var wsId) ? wsId : throw new InvalidOperationException("POWERBI_WORKSPACE_ID environment variable is not set or is not a valid GUID.");

var authenticationResult = await ConfidentialClientApplicationBuilder
    .Create(clientId)
    .WithClientSecret(clientSecret)
    .WithAuthority($"https://login.microsoftonline.com/{tenant}")
    .Build()
    .AcquireTokenForClient(["https://analysis.windows.net/powerbi/api/.default"]).ExecuteAsync();

var powerBiClient = new PowerBIClient(new Uri("https://api.powerbi.com"), new TokenCredentials(authenticationResult.AccessToken, authenticationResult.TokenType));

var dataSets = (await powerBiClient.Datasets.GetDatasetsInGroupAsync(workspaceId)).Value.ToDictionary(x => x.Id);

foreach (var dataset in dataSets.Values)
{
    Console.WriteLine($"id: {dataset.Id} - IsEffectiveIdentityRequired: {dataset.IsEffectiveIdentityRequired} - IsRefreshable: {dataset.IsRefreshable}");
}

Output: id: <guid> - IsEffectiveIdentityRequired: False - IsRefreshable: True

v5:

#:property PublishAot=false
#:package Azure.Identity@1.17.1
#:package Microsoft.PowerBI.Api@5.0.0

using System.Diagnostics;
using Azure.Identity;
using Microsoft.PowerBI.Api;

Console.WriteLine("Power BI SDK 5.x example");

var clientId = Environment.GetEnvironmentVariable("POWERBI_CLIENT_ID") ?? throw new InvalidOperationException("POWERBI_CLIENT_ID environment variable is not set.");
var clientSecret = Environment.GetEnvironmentVariable("POWERBI_CLIENT_SECRET") ?? throw new InvalidOperationException("POWERBI_CLIENT_SECRET environment variable is not set.");
var tenant = Environment.GetEnvironmentVariable("POWERBI_CLIENT_TENANT") ?? throw new InvalidOperationException("POWERBI_CLIENT_TENANT environment variable is not set.");
Guid workspaceId = Environment.GetEnvironmentVariable("POWERBI_WORKSPACE_ID") is string workspaceIdString && Guid.TryParse(workspaceIdString, out var wsId) ? wsId : throw new InvalidOperationException("POWERBI_WORKSPACE_ID environment variable is not set or is not a valid GUID.");

PowerBIClient client = new(new ClientSecretCredential(tenant, clientId, clientSecret));

var dataSets = (await client.Datasets.GetDatasetsInGroupAsync(workspaceId)).Value.Value.ToDictionary(x => x.Id);
foreach (var dataset in dataSets.Values)
{
    Console.WriteLine($"id: {dataset.Id} - IsEffectiveIdentityRequired: {dataset.IsEffectiveIdentityRequired} - IsRefreshable: {dataset.IsRefreshable}");
}

Output: id: <guid> - IsEffectiveIdentityRequired: - IsRefreshable:

As you can see, the properties are lost.

@KupoCat can you look at this please?

@ayeshurun can you look at this please?

@KupoCat @ayeshurun I found the same issue back in November 2025 and tried to email people at Microsoft (got the email addresses from the git commits) but heard no reply.

The issue was introduced with the commit that switched to AutoRest V3 (3a88dcb)

I believe the issue affects many more objects and properties than just Dataset. It would be great if this repo accepted issues so the problems can be reasonably logged.

This is now support request 2603131420000271. Let's see if that gets attention here

And PowerBI SDK 5.1 has been released 2 hours ago, with this fix. Coincidence?
