What is it?

The Microsoft .NET Framework 4.5 Developer Pack is a software development component specifically designed for developers building applications using Visual Studio or other IDEs. Unlike the standard end-user runtime (which only allows running .NET 4.5 applications), the Developer Pack includes everything a developer needs to build, debug, and target applications for the .NET Framework 4.5.

It contains:

  • The .NET Framework 4.5 Runtime (full redistributable).
  • The associated software development kits (SDKs).
  • IntelliSense files for Visual Studio.
  • Reference assemblies required for compilation.
  • Multi-targeting packs, allowing older versions of Visual Studio (e.g., VS 2012, 2013) to target .NET 4.5.

Step 1: Verify Prerequisites

  • Ensure Windows is fully updated (especially KB2781514 for Windows 7 SP1).
  • Close all instances of Visual Studio.

Step 4: Verification

To confirm the Developer Pack installed correctly:

  • In Visual Studio, create a new project.
  • Go to Project Properties > Application > Target Framework.
  • You should see .NET Framework 4.5 in the list.
  • Alternatively, check the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full
    • Look for Version = 4.5.xxxxxxxx and Install = 1.
