Deploying ASP.NET Core to IIS on Windows Server — ShopNest
Article 59 of 75 · Module 8: Deployment & DevOps · ShopNest Corporate Internal Application
Target keyword: deploy asp.net core iis · Read time: ~30 min · .NET: 8 / 9 · Project: ShopNest Corporate Internal Application

Introduction

Many Indian enterprises still host on Windows Server + IIS. ShopNest internal admin apps deploy behind IIS using the ASP.NET Core Module — not in-process IIS .NET Framework.

After this article you will

  • Publish ShopNest from CLI and Visual Studio
  • Configure IIS app pool and site
  • Fix 500.30 and 502.5 startup errors
  • Set environment variables in IIS
  • Automate with Web Deploy

Prerequisites

Concept deep-dive

dotnet publish ShopNest.Web -c Release -o ./publish

# IIS prerequisites:
# - Hosting Bundle (ASP.NET Core Runtime + Module)
# - App Pool: No Managed Code, Integrated pipeline
<!-- web.config generated on publish -->
<aspNetCore processPath="dotnet" arguments=".ShopNest.Web.dll"
  stdoutLogEnabled="true" stdoutLogFile=".logsstdout"
  hostingModel="inprocess">
  <environmentVariables>
    <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
  </environmentVariables>
</aspNetCore>

502.5: app failed to start — check Event Viewer, enable stdout logs, verify Hosting Bundle installed. 500.30: startup exception — wrong connection string or missing DLL.

Hands-on — ShopNest Corporate Internal Application

  1. Publish Release folder to server path.
  2. Create IIS site pointing to publish folder.
  3. Install Hosting Bundle; restart IIS.
  4. URL Rewrite for HTTP→HTTPS.
  5. Web Deploy profile from Visual Studio for updates.

Common errors & best practices

  • App pool .NET CLR v4 — must be No Managed Code.
  • 32-bit app pool on 64-bit publish — mismatch.
  • Permissions on logs folder for stdout.

Interview questions

Q: Why No Managed Code?
A: ASP.NET Core runs out-of-process/in-process via Kestrel + Module, not IIS CLR.

Q: web.config role?
A: Tells IIS how to launch dotnet and set env vars.

Summary

  • Install Hosting Bundle before deploy
  • App pool No Managed Code + Integrated
  • stdout logs diagnose startup failures
  • Web Deploy automates corporate updates

Previous: Test-Driven Development
Next: Docker and Containerization

FAQ

Multiple sites?

Separate app pools per site; shared Hosting Bundle OK.

In-process vs out-of-process?

In-process faster on Windows; out-of-process more isolation.
