Framwork versions RRS feed

  • Question

  • Hello, I'm supporting an application that was developed in C# and had the targeting framework set to 4.5 and I'm also on Win7

    My question is, I have an .Net Framework installer  NDP452-KB2901951-x86-x64-DevPack.exe  So will that work for an application that was targeting 4.5?   The install for NDP452-KB2901951-x86-x64-DevPack.exe went pretty quick

    # You can choose a targeting version as you like, if it (adequate version of DevPack) is installed. 

    I have checked if the issue can be reproduced in my environment. At first, I installed NDP452-KB2901951-x86-x64-DevPack.exe (336,213 KB).
    env-1: Windows 8.1 Pro 64-bit, Virtual Studio Pro 2013 (already installed) -- no problem (could not reproduced)

    I will try with other environment (Windows 7 Ultimate 64-bit).  Visual Studio is not installed in this env. I would like to make my env. as much as the same as yours. Please provide your Visual Studio version.

  • Hi William256,

    Thank you for posting here.

    According to the description on the MSDN installation article, the .exe file is for .net framework 4.5.2. Please migrate your application from .net framework 4.5 to .net framework 4.5.2.

    And update your Win7 to Win7 SP1. 


    Best Regards,
