.NET Core 10 Hosting: Complete Guide for 2026

.NET Core 10 LTS is Microsoft's most ambitious release of the .NET runtime — three years of long-term support, native AI integration, post-quantum cryptography, and what Microsoft itself calls "the fastest .NET ever." But shipping a .NET 10 application to production exposes the same set of hosting trade-offs that have always quietly determined whether your app stays fast and reliable.

This guide covers what .NET Core 10 actually delivers, the hosting requirements that let those features land in production, and what's included on every Adaptive .NET Core 10 hosting plan.

What's New in .NET Core 10

Microsoft released .NET 10 in November 2025 as a Long-Term Support (LTS) version, with mainstream support until November 2028. For teams shipping new applications today, .NET 10 is the right baseline — both for the runtime improvements and for the three-year patch window.

Built-in AI Support

builder.Services.AddChatClient(sp =>
new OpenAIChatClient(apiKey, "gpt-4o"));
app.MapPost("/chat", async (string prompt, IChatClient chat) =>
await chat.CompleteAsync(prompt));

This is the same abstraction Microsoft uses in Semantic Kernel and Azure AI Foundry, and it makes multi-agent systems substantially easier to build.

Fastest .NET Ever

.NET 10 delivers measurable runtime improvements over .NET 9:

• JIT inlining — more methods inlined, fewer call-site stalls
• Method devirtualization — the runtime resolves virtual calls statically when it can
• AVX10.2 SIMD support — for code that uses Vector or System.Numerics
• NativeAOT improvements — smaller binaries, faster cold starts
• Server GC enhancements — reduced Gen-2 pause times on memory-heavy workloads

For a typical ASP.NET Core 10 application, expect 5–15% throughput gains over .NET 9 without any code changes.

Post-Quantum Cryptography

NIST standardized the first post-quantum cryptographic algorithms in 2024, and .NET 10 ships native support for two of them:

| Algorithm | Purpose | Why It Matters |

|---|---|---|

| ML-KEM (Key Encapsulation) | Asymmetric key exchange resistant to quantum attack | Future-proofs TLS handshakes against "harvest now, decrypt later" |

| ML-DSA (Digital Signature) | NIST-standardized PQ signatures | Required for compliance-driven workloads with long-term data confidentiality |

Combined with TLS 1.3 (default in .NET 10), this puts hybrid post-quantum certificates within reach for production workloads in 2026.

ASP.NET Core 10 Highlights

• OpenAPI 3.1 — first-class support, replacing Swashbuckle in most workflows
• YAML output for dotnet openapi — easier to commit to source control
• Passkey support in Identity — WebAuthn-based passwordless authentication
• Improved Blazor features — render-mode unification across Server, WebAssembly, and Static SSR

Entity Framework Core 10

• AI-ready vector search — VECTOR(N) column types for embedding storage
• Hybrid semantic + full-text search — combine traditional FTS with vector similarity
• Native JSON types in SQL Server 2022 — query JSON columns with type-safe LINQ

What .NET Core 10 Hosting Should Look Like

Modern runtime features only land in production when the hosting layer cooperates. Here's what to look for:

1. Real Windows Server 2022 + IIS 10

Many "ASP.NET hosting" providers run .NET as a sidecar on Linux containers. That works for trivial APIs, but loses you native IIS handlers, integrated Windows authentication, and the full ASP.NET 2.0–4.8 back-version compatibility most teams still need.

Adaptive runs .NET 10 on Windows Server 2022 with IIS 10 — the configuration Microsoft itself optimizes for.

2. Dedicated IIS Application Pools

When .NET 10's Dynamic PGO is profiling your hot paths for the first 30 seconds, the last thing you want is your app pool getting recycled to free memory for a noisy neighbor. Every Adaptive plan gives you dedicated IIS Application Pools sized to your tier:

| Plan | App Pool RAM | Websites | Price |

|---|---|---|---|

| Developer | 1 GB | 2 | $9.49/mo |

| Business | 2 GB | 5 | $17.49/mo |

| Professional | 4 GB | 10 | $27.49/mo |

Higher tiers also include Higher Priority Resource Scheduling (Business and Professional) and Higher Priority CPU Scheduling (Professional).

3. Real SQL Server 2022 — and MariaDB Alongside

EF Core 10's most interesting features — vector search, native JSON columns, hybrid full-text/semantic search — require SQL Server 2022 features that don't exist in SQL Server Express. If your hosting provider's "SQL Server" is Express, you're capped before you start.

Every Adaptive plan includes full SQL Server 2022 databases (not Express): 2 on Developer, 5 on Business, 10 on Professional. You also get the same number of MariaDB databases alongside — handy for hybrid stacks running .NET and PHP-based applications side-by-side.

4. Continuous Deployment Support

• WebDeploy for IDE and CI publishing
• Plesk Control Panel with Git deploy, scheduled tasks, log viewer
• FTP/SFTP for traditional uploads
• Compatible with GitHub Actions, Azure DevOps, GitLab CI, Bitbucket Pipelines, and any pipeline that produces a dotnet publish artifact

5. Security That Matches .NET 10

.NET 10's post-quantum cryptography and Identity passkey support deserve a hosting layer that backs them up. Adaptive ships:

• DDoS protection at the network edge
• Web Application Firewall with managed signature updates
• FREE SSL on every site
• Hardened Windows Server 2022 baseline with regular security patching
• Dedicated app pools — a vulnerability in one tenant doesn't pivot to others

Migration: .NET 6 / 7 / 8 / 9 → .NET 10 LTS

If you're moving from an older runtime, here's the typical path:

• Update ` to net10.0
• Update NuGet packages — most mainstream packages have .NET 10 builds already
• Review middleware order — minor defaults shifted between .NET 9 and 10
• Test SignalR clients — protocol bumps may require client updates
• Re-publish with the .NET 10 SDK

public class Document
{
public int Id { get; set; }
public string Title { get; set; } = "";
[Column(TypeName = "VECTOR(1536)")]
public float[] Embedding { get; set; } = [];
}
// Find similar documents
var similar = await context.Documents
.OrderBy(d => EF.Functions.VectorDistance(d.Embedding, queryVector))
.Take(10)
.ToListAsync();

Yes. The IIS handlers on our Windows Server 2022 infrastructure run AOT-compiled ASP.NET Core binaries natively. Just publish with true and deploy as you would any other build.

SQL Server 2022 — which every Adaptive plan includes — supports the VECTOR` data type that EF Core 10 maps to. You can store embeddings and run cosine-distance queries without integrating a separate vector database.

Can I deploy from GitHub Actions?

Yes. We support WebDeploy from CI pipelines, Plesk Git, and FTP/SFTP. See our CI/CD guide for a complete GitHub Actions example targeting IIS.

Is there a free trial?

We don't offer a separate trial, but every plan ships with a 30-Day Money-Back Guarantee. You can deploy your .NET 10 application, validate performance, and request a full refund within the first 30 days if it's not the right fit.
