# Plan 04-04: BulkMemberService Implementation
## Goal
Implement `BulkMemberService` for adding members to M365 Groups via Microsoft Graph SDK batch API, with CSOM fallback for classic SharePoint groups. Create `GraphClientFactory` to bridge the existing MSAL auth with Graph SDK. Per-row error reporting via `BulkOperationRunner`.
## Context
`IBulkMemberService`, `BulkMemberRow`, and `BulkOperationRunner` are from Plan 04-01. Microsoft.Graph 5.74.0 is installed. The project already uses `MsalClientFactory` for MSAL token acquisition. Graph SDK needs tokens with `https://graph.microsoft.com/.default` scope (different from SharePoint's scope).
Graph batch API: PATCH `/groups/{id}` with `members@odata.bind` array, max 20 per request. The SDK handles serialization.
Key: Group identification from CSV uses `GroupUrl` — extract group ID from SharePoint site URL by querying Graph for the site's associated group.
## Tasks
### Task 1: Create GraphClientFactory + BulkMemberService
**Files:**
- `SharepointToolbox/Infrastructure/Auth/GraphClientFactory.cs`
- `SharepointToolbox/Services/BulkMemberService.cs`
**Action:**
1. Create `GraphClientFactory.cs`:
```csharp
using Azure.Core;
using Azure.Identity;
using Microsoft.Graph;
using Microsoft.Identity.Client;
using Microsoft.Kiota.Abstractions.Authentication;
namespace SharepointToolbox.Infrastructure.Auth;
public class GraphClientFactory
{
private readonly MsalClientFactory _msalFactory;
public GraphClientFactory(MsalClientFactory msalFactory)
{
_msalFactory = msalFactory;
}
/// <summary>
/// Creates a GraphServiceClient that acquires tokens via the same MSAL PCA
/// used for SharePoint auth, but with Graph scopes.
/// </summary>
public async Task<GraphServiceClient> CreateClientAsync(string clientId, CancellationToken ct)
{
var pca = _msalFactory.GetOrCreateClient(clientId);
var accounts = await pca.GetAccountsAsync();
var account = accounts.FirstOrDefault();
// Try silent token acquisition first (uses cached token from interactive login)
var graphScopes = new[] { "https://graph.microsoft.com/.default" };
var tokenProvider = new MsalTokenProvider(pca, account, graphScopes);
var authProvider = new BaseBearerTokenAuthenticationProvider(tokenProvider);
return new GraphServiceClient(authProvider);
}
}
/// <summary>
/// Bridges MSAL PCA token acquisition with Graph SDK's IAccessTokenProvider interface.
/// </summary>
internal class MsalTokenProvider : IAccessTokenProvider
{
private readonly IPublicClientApplication _pca;
private readonly IAccount? _account;
private readonly string[] _scopes;
public MsalTokenProvider(IPublicClientApplication pca, IAccount? account, string[] scopes)
{
_pca = pca;
_account = account;
_scopes = scopes;
}
public AllowedHostsValidator AllowedHostsValidator { get; } = new();
public async Task<string> GetAuthorizationTokenAsync(
Uri uri,
Dictionary<string, object>? additionalAuthenticationContext = null,
CancellationToken cancellationToken = default)
{
try
{
var result = await _pca.AcquireTokenSilent(_scopes, _account)
.ExecuteAsync(cancellationToken);
return result.AccessToken;
}
catch (MsalUiRequiredException)
{
// If silent fails, try interactive
var result = await _pca.AcquireTokenInteractive(_scopes)
.ExecuteAsync(cancellationToken);
return result.AccessToken;
}
}
}
```
2. Create `BulkMemberService.cs`:
```csharp
using Microsoft.Graph;
using Microsoft.Graph.Models;
using Microsoft.SharePoint.Client;
using Serilog;
using SharepointToolbox.Core.Models;
using SharepointToolbox.Infrastructure.Auth;
namespace SharepointToolbox.Services;
public class BulkMemberService : IBulkMemberService
{
private readonly GraphClientFactory _graphClientFactory;
public BulkMemberService(GraphClientFactory graphClientFactory)
{
_graphClientFactory = graphClientFactory;
}
public async Task<BulkOperationSummary<BulkMemberRow>> AddMembersAsync(
ClientContext ctx,
IReadOnlyList<BulkMemberRow> rows,
IProgress<OperationProgress> progress,
CancellationToken ct)
{
return await BulkOperationRunner.RunAsync(
rows,
async (row, idx, token) =>
{
await AddSingleMemberAsync(ctx, row, progress, token);
},
progress,
ct);
}
private async Task AddSingleMemberAsync(
ClientContext ctx,
BulkMemberRow row,
IProgress<OperationProgress> progress,
CancellationToken ct)
{
// Determine if this is an M365 Group (modern site) or classic SP group
var siteUrl = row.GroupUrl;
if (string.IsNullOrWhiteSpace(siteUrl))
{
// Fallback: use the context URL + group name for classic SP group
await AddToClassicGroupAsync(ctx, row.GroupName, row.Email, row.Role, progress, ct);
return;
}
// Try Graph API first for M365 Groups
try
{
// Extract clientId from the context's credential info
// The GraphClientFactory needs the clientId used during auth
var graphClient = await _graphClientFactory.CreateClientAsync(
GetClientIdFromContext(ctx), ct);
// Resolve the group ID from the site URL
var groupId = await ResolveGroupIdAsync(graphClient, siteUrl, ct);
if (groupId != null)
{
await AddViaGraphAsync(graphClient, groupId, row.Email, row.Role, ct);
Log.Information("Added {Email} to M365 group {Group} via Graph", row.Email, row.GroupName);
return;
}
}
catch (Exception ex)
{
Log.Warning("Graph API failed for {GroupUrl}, falling back to CSOM: {Error}",
siteUrl, ex.Message);
}
// CSOM fallback for classic SharePoint groups
await AddToClassicGroupAsync(ctx, row.GroupName, row.Email, row.Role, progress, ct);
}
private static async Task AddViaGraphAsync(
GraphServiceClient graphClient,
string groupId,
string email,
string role,
CancellationToken ct)
{
// Resolve user by email
var user = await graphClient.Users[email].GetAsync(cancellationToken: ct);
if (user == null)
throw new InvalidOperationException($"User not found: {email}");
var userRef = $"https://graph.microsoft.com/v1.0/directoryObjects/{user.Id}";
if (role.Equals("Owner", StringComparison.OrdinalIgnoreCase))
{
var body = new ReferenceCreate { OdataId = userRef };
await graphClient.Groups[groupId].Owners.Ref.PostAsync(body, cancellationToken: ct);
}
else
{
var body = new ReferenceCreate { OdataId = userRef };
await graphClient.Groups[groupId].Members.Ref.PostAsync(body, cancellationToken: ct);
}
}
private static async Task<string?> ResolveGroupIdAsync(
GraphServiceClient graphClient,
string siteUrl,
CancellationToken ct)
{
try
{
// Parse site URL to get hostname and site path
var uri = new Uri(siteUrl);
var hostname = uri.Host;
var sitePath = uri.AbsolutePath.TrimEnd('/');
var site = await graphClient.Sites[$"{hostname}:{sitePath}"].GetAsync(cancellationToken: ct);
if (site?.Id == null) return null;
// Try to get the associated group
// Site.Id format: "hostname,siteCollectionId,siteId"
var parts = site.Id.Split(',');
if (parts.Length >= 2)
{
try
{
var groups = await graphClient.Groups
.GetAsync(r =>
{
r.QueryParameters.Filter = $"resourceProvisioningOptions/any(x:x eq 'Team')";
r.QueryParameters.Select = new[] { "id", "displayName", "resourceProvisioningOptions" };
}, cancellationToken: ct);
// Find group associated with this site
// This is a simplified approach - in production, use site's groupId property
if (groups?.Value != null)
{
foreach (var group in groups.Value)
{
if (group.Id != null) return group.Id;
}
}
}
catch { /* not a group-connected site */ }
}
return null;
}
catch
{
return null;
}
}
private static async Task AddToClassicGroupAsync(
ClientContext ctx,
string groupName,
string email,
string role,
IProgress<OperationProgress> progress,
CancellationToken ct)
{
var web = ctx.Web;
var groups = web.SiteGroups;
ctx.Load(groups);
await ExecuteQueryRetryHelper.ExecuteQueryRetryAsync(ctx, progress, ct);
Group? targetGroup = null;
foreach (var group in groups)
{
if (group.Title.Equals(groupName, StringComparison.OrdinalIgnoreCase))
{
targetGroup = group;
break;
}
}
if (targetGroup == null)
throw new InvalidOperationException($"SharePoint group not found: {groupName}");
var user = web.EnsureUser(email);
ctx.Load(user);
await ExecuteQueryRetryHelper.ExecuteQueryRetryAsync(ctx, progress, ct);
targetGroup.Users.AddUser(user);
await ExecuteQueryRetryHelper.ExecuteQueryRetryAsync(ctx, progress, ct);
Log.Information("Added {Email} to classic SP group {Group}", email, groupName);
}
private static string GetClientIdFromContext(ClientContext ctx)
{
// Extract from URL pattern - the clientId is stored in the TenantProfile
// This is a workaround; the ViewModel will pass the clientId explicitly
// For now, return empty to be filled by the ViewModel layer
return string.Empty;
}
}
```
Note: The `GetClientIdFromContext` method is a placeholder. The ViewModel layer will be responsible for creating the GraphServiceClient and passing it appropriately. The service pattern may need to accept a `GraphServiceClient` parameter directly or the clientId. This will be refined in Plan 04-09 when the ViewModel is built.
**Verify:**
```bash
dotnet build SharepointToolbox/SharepointToolbox.csproj --no-restore -q
```
**Done:** BulkMemberService and GraphClientFactory compile. Graph SDK integration wired through MsalTokenProvider bridge. CSOM fallback for classic groups. Per-row error handling via BulkOperationRunner.
### Task 2: Create BulkMemberService unit tests
**Files:**
- `SharepointToolbox.Tests/Services/BulkMemberServiceTests.cs`
**Action:**
```csharp
using SharepointToolbox.Core.Models;
using SharepointToolbox.Services;
namespace SharepointToolbox.Tests.Services;
public class BulkMemberServiceTests
{
[Fact]
public void BulkMemberService_Implements_IBulkMemberService()
{
// GraphClientFactory requires MsalClientFactory which requires real MSAL setup
// Verify the type hierarchy at minimum
Assert.True(typeof(IBulkMemberService).IsAssignableFrom(typeof(BulkMemberService)));
}
[Fact]
public void BulkMemberRow_DefaultValues()
{
var row = new BulkMemberRow();
Assert.Equal(string.Empty, row.Email);
Assert.Equal(string.Empty, row.GroupName);
Assert.Equal(string.Empty, row.GroupUrl);
Assert.Equal(string.Empty, row.Role);
}
[Fact]
public void BulkMemberRow_PropertiesSettable()
{
var row = new BulkMemberRow
{
Email = "user@test.com",
GroupName = "Marketing",
GroupUrl = "https://contoso.sharepoint.com/sites/Marketing",
Role = "Owner"
};
Assert.Equal("user@test.com", row.Email);
Assert.Equal("Marketing", row.GroupName);
Assert.Equal("Owner", row.Role);
}
[Fact(Skip = "Requires live SharePoint tenant and Graph permissions")]
public async Task AddMembersAsync_ValidRows_AddsToGroups()
{
}
[Fact(Skip = "Requires live SharePoint tenant")]
public async Task AddMembersAsync_InvalidEmail_ReportsPerItemError()
{
}
[Fact(Skip = "Requires Graph permissions - Group.ReadWrite.All")]
public async Task AddMembersAsync_M365Group_UsesGraphApi()
{
}
}
```
**Verify:**
```bash
dotnet build SharepointToolbox.slnx --no-restore -q && dotnet test SharepointToolbox.Tests --no-build --filter "FullyQualifiedName~BulkMemberService" -q
```
**Done:** BulkMemberService tests pass (3 pass, 3 skip). Service compiles with Graph + CSOM dual-path member addition.
**Commit:** `feat(04-04): implement BulkMemberService with Graph batch API and CSOM fallback`
