Voorbeelden van SOAP-clientbibliotheek voor Azure DevOps

Azure DevOps Services | Azure DevOps Server | Azure DevOps Server 2022

Dit artikel bevat voorbeelden voor integratie met Azure DevOps Server en Azure DevOps Services met behulp van verouderde SOAP-clients. Deze clients zijn alleen beschikbaar in de .NET Framework-versie en vereisen plaatselijke of verouderde verificatiemethoden.

Vereisten en beperkingen

Vereisten:

• .NET Framework 4.6.1 of hoger
• Verouderde NuGet-pakketten
• Windows-omgeving voor SOAP-clientondersteuning

Beperkingen:

• ❌ Geen ondersteuning voor .NET Core of .NET 5+
• ❌ Beperkte opties voor moderne verificatie
• ❌ Geen async/await-patronen
• ❌ Verminderde prestaties vergeleken met REST-clients
• ❌ Beperkte toekomstige ondersteuning en updates

Vereiste NuGet-pakketten:

• Microsoft.TeamFoundationServer.ExtendedClient - Verouderde SOAP-clients
• Microsoft.TeamFoundationServer.Client - Core Azure DevOps-API's
• Microsoft.VisualStudio.Services.Client - Verbinding en verificatie
• Microsoft.VisualStudio.Services.InteractiveClient - Interactieve verificatiestromen

Migratierichtlijnen

Aanbevolen migratiepad

Stap 1: Uw huidige gebruik evalueren

• SOAP-specifieke functionaliteit identificeren die uw toepassing gebruikt
• Bepalen of equivalente REST API's beschikbaar zijn
• Verificatievereisten evalueren

Stap 2: Migratiestrategie plannen

• Onmiddellijk: Verificatie bijwerken om PAT's of Microsoft Entra-id te gebruiken
• Korte termijn: Migreren naar OP REST gebaseerde clients terwijl .NET Framework behouden blijft
• Lange termijn: moderniseren naar .NET Core/.NET 5+ met REST-clients

Stap 3: Migratie implementeren

• Begin met verificatie-updates. Bekijk de volgende voorbeelden.
• SOAP-clients incrementeel vervangen door REST-equivalenten
• Test grondig voordat u naar productie uitrolt

Zie voorbeelden van .NET-clientbibliotheek voor gedetailleerde migratierichtlijnen.

Migratie naar moderne clients

Vergelijking naast elkaar

Legacy SOAP-benadering:

// ❌ Legacy SOAP pattern
using (var tpc = new TfsTeamProjectCollection(uri, credentials))
{
    var workItemStore = tpc.GetService<WorkItemStore>();
    var workItems = workItemStore.Query("SELECT * FROM WorkItems");
    // Synchronous, blocking operations
}

Moderne REST-benadering:

// ✅ Modern REST pattern
using var connection = new VssConnection(uri, credentials);
var witClient = connection.GetClient<WorkItemTrackingHttpClient>();
var workItems = await witClient.QueryByWiqlAsync(new Wiql { Query = "SELECT * FROM WorkItems" });
// Asynchronous, non-blocking operations

Belangrijkste verschillen

Problemen met verouderde clients oplossen

Veelvoorkomende problemen en oplossingen

Verificatiefouten:

• Zorg ervoor dat PAT's over de juiste toepassingen beschikken.
• Indeling van organisatie-URL controleren (inclusief verzameling voor on-premises)
• Firewall- en proxy-instellingen voor SOAP-eindpunten controleren

Prestatieproblemen:

• SOAP-clients zijn inherent langzamer dan REST
• Overweeg waar mogelijk batchbewerkingen
• Migreren naar REST-clients voor betere prestaties

Platformcompatibiliteit:

• SOAP-clients werken alleen op .NET Framework
• REST-clients gebruiken voor platformoverschrijdende ondersteuning
