Shared Hosting Retiring Legacy ASP.NET Core Versions (April 2026)

20 January 2026

At Web Wiz, we are committed to providing a secure and high-performance hosting environment for your applications. To maintain these standards, we are announcing the formal removal of several "End of Life" (EOL) ASP.NET Core versions from our shared hosting servers.

What is Changing?
Effective April  2026, the following legacy .NET Core frameworks will be decommissioned and removed from our shared hosting service:

  • .NET Core: 2.1, 2.2, 3.0, 3.1
  • ASP.NET 5 (.Net Core 5)
  • ASP.NET 6 (.Net Core 6)
  • ASP.NET 7 (.Net Core 7)

After this date, applications targeting these versions will no longer run on our infrastructure.

Why is this happening? 
The primary driver for this removal is security. These versions have long passed their official support window from Microsoft, meaning they no longer receive critical security patches.

Specifically, we have seen an increase in vulnerabilities related to CSV, Remove Code Execution (RCE) and Data Injection. Older frameworks often lack the modern, built-in sanitisation libraries required to defend against leaving the website and web server vulnerable to attacks. 

By moving to supported versions (such as ASP.NET 8, ASP.NET 9 or ASP.NET 10), you benefit from updated security, better encryption standards, and native protection against modern injection flaws.


What You Need to Do
To avoid any service interruption, please take the following steps before the April 2026 deadline:
  1. Identify: Check your project's .csproj file or your hosting settings to see which framework version you are currently using.

  2. Upgrade: We strongly recommend upgrading to ASP.NET 10 (LTS) or higher. These versions offer long-term support and significantly improved performance.

  3. Test: Deploy your upgraded application to a staging environment to ensure compatibility with modern libraries.

What if you can't move to a newer ASP.NET version
If you are unable to update your application to a newer version of ASP.NET and are happy to accept the security risks, we can provide custom hosting plans that can support legacy applications and frameworks through our Dedicated Wen Hosting, for more info see; Windows Dedicated Web Hosting 


Classic ASP and Classic ASP.NET is NOT Affected
We want to emphasise that Classic ASP and Classic ASP.NET is NOT being removed at this time. If your application relies on the following, your service will remain active:

  • Classic ASP: Microsoft has no end-of-support date currently set for Classic ASP.
  • ASP.NET 2.0 / 3.0 / 3.5: Microsoft has confirmed support for these versions until at least January 2029.
  • ASP.NET 4.0 / 4.5 / 4.6: Microsoft has no end-of-support date currently set for these versions.

We appreciate your cooperation in keeping our platform—and your data—secure.
