File version history for CLR 4.x

  • Article

In the past I have maintained some blogs posts about version histories of the CLR 2.0 and CLR 4.0. People seem to have found those useful over the years but they have become quite tough to maintain. With that in mind, I’m drawing a line under those old posts for now and making a bit of a fresh start here, capturing some of the newer key versions of the CLR 4.x family that have shipped.  I’ll try to update over time.

Version number indicated refers to CLR.DLL. If there are patches of significant interest relating to other files I’ll note that in the ‘File’ column.

    Its very much confusing area of choosing the development assemblies then choosing the deployment assemblies as well as consider the target architecture using to many ambiguous command prompts Developer Command Prompt for VS2015 ??MSBuild Command Prompt for VS2015 ??VS2015 x64 ARM Cross Tools Command Prompt ??VS2015 x64 Native Tools Command Prompt :: x64 Native is the tools targeting 64 bit Windows and the executables are 64 bit. VS2015 x64 x86 Cross Tools Command Prompt :: x64 Cross is the tools targeting 64 bit Windows and the executables are 32 bit.VS2015 x86 ARM Cross Tools Command Prompt ??VS2015 x86 Native Tools Command Prompt :: x86 Native is the tools targeting 32 bit Windows and the executables are 32 bit.VS2015 x86 x64 Cross Tools Command Prompt ??The new formatted system with single OS Windows Server 2016 DataCenter comes with (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP) versions 2.0.50727, 3.0, 3.5, 4, 4.0 ( 4 vs 4.0 ??? )So I was searching System.Data.dll and found 22 dlls in C:\ drive; similarly System.dll,(26), System.Web.dll(14), mscoree.dll(for loading correct version CLR) is 7.After this exercise I installed VS2015(which comes with 4.5, 4.5.1, 4.5.2, 4.6) and found dll counts reaching 35+. The folder "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework" has many .net versions and magic is many of types inside dlls refers to GAC. Then I developed WebAPI CRUD application simple; then moment I hit "Build" it went to Nuget Laboratory and found lots of unwanted fruits for me. Since VS has selected 4.5.1 but IIS 10 has asp.net 4.0.30319 from OS installation. And when I deployed this as web app in "Default Web Site" and I got "Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.1586.0" (4.6.15860 ???? csproj properties showing 4.5.2 ?? Weird !! ). May be after 10 years Microsoft would come with .Net Premium Framework. Till then bear it.
