PeterI'm assuming that you already have a pool on your Windows Server IIS when you read this article. To learn how to publish ASP.NET Core 10 applications on IIS environments, follow these steps.
You must configure the project to run on the architecture from the target pool and set up your code to support IIS. Verify the inetmgr console, the Advanced setting, and whether Enable 32-Bit programs is set to true to determine whether your pool is operating on x86.
Application Pools
Let's do the steps to publish
You need to setup the x86 platform for your project to run on IIS as x86 aplication.
And create a publish profile selecting the x86 release.
Step 1. Start your new ASP.NET Core MVC
dotnet new mvc -n MyTestApp
Step 2. Choose your architecture pool. It should be the same as the pool on IIS (x86 for 32 bits).
2.1. From Visual Studio 2026 select Configuration Manager.
Menu Configurations
2.2 Select "New..."
2.3 Type the platform "x86" and press OK.

Now you can publihs it copying the files to the IIS target folder on Windows Server.
Important
Before the deploy on the IIS you need to install on the WIndows Server the .NET 10 Hosting Bundle
Hosting Bundle option.
Conclusion
There are a few steps, but it is essential to follow them to succeed in publishing ASP.NET Core 10 applications.
