Overview

What .NET does

.NET is Microsoft's open source developer platform, with LTS releases supported 3 years and STS releases supported 2 years from launch.

What people use it for

  • Web development with ASP.NET Core and Entity Framework
  • Cloud-native application development for Azure
  • Mobile and desktop apps with .NET MAUI cross-platform framework
  • AI and machine learning applications using C#

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about .NET.

  • .NET 8 and .NET 9 both reach end of support on 10 November 2026, per dotnet.microsoft.com/en-us/platform/support/policy (Aug 2026), forcing an upgrade to .NET 10 by that date
  • Standard Term Support releases get only 2 years of patches versus 3 years for Long Term Support releases, per Microsoft's own support policy page, so teams on an STS release face a shorter upgrade cycle

Cross-shopped

What people choose instead of .NET

Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for .NET, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
