Install Microsoft .NET Framework 4.5.1 Developer Pack (KB2861696) silently
The unattended switch below is the one Microsoft Corporation declares in the installer manifest, not one we guessed by trying flags.
32-bit · publisher-declared
.\NDP452-KB2901951-x86-x64-DevPack.exe /install /quiet /norestartRun it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.

Is Microsoft .NET Framework 4.5.1 Developer Pack (KB2861696) safe to download?
The installer does not come from Microsoft Corporation. That is worth knowing before you run it, and it is why this page carries a warning above.
The installer on this page comes with the SHA-256 Microsoft Corporation declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.

Old versions of Microsoft .NET Framework 4.5.1 Developer Pack (KB2861696)1 with hashes
The version history of Microsoft .NET Framework 4.5.1 Developer Pack (KB2861696), each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.
