Notes

• The target frameworks added by this update to Microsoft Visual Studio for projects to use are ".NET Framework 4.0.3" and ".NET Framework 4.0.3 Client Profile."
• After you apply this multi-targeting pack, you can build new projects that use the .NET Framework 4.0.3.
  
  Note You can build new projects that use the features that are introduced in .NET Framework 4.0.1, .NET Framework 4.02, or .NET Framework 4.0.3 runtimes.
• Multi-Targeting Pack for the Microsoft .NET Framework 4.0.3 is cumulative. It includes all the related files from multi-targeting packs for the .NET Framework 4.0.1 and for the .NET Framework 4.0.2. Therefore, you do not have to install the previous multi-targeting packs separately after you install Multi-Targeting Pack for the Microsoft .NET Framework 4.0.3 for building any new projects.
• But the Multi-Targeting Pack for the Microsoft .NET Framework 4.0.3 exposes only .NET Framework 4.0.3 targets. For example, this update exposes only the .NET Framework 4.0.3 targeting, and does not expose the targeting for the .NET Framework 4.0.1 or for the .NET Framework 4.0.2.
• The targeting for the .NET Framework 4.0.1 and the .NET Framework 4.0.2 can coexist with the targeting for the .NET Framework 4.0.3. You can still use the previous targeting for any existing projects built for the .NET Framework 4.0.1 and for the .NET Framework 4.0.2. However, each version has to be installed by using its own installation package.
