is it posible to use RyuJIT with earlier frameworks than 4.6?

There is my question sorry if it's silly but is it posible to use RyuJIT with earlier frameworks than 4.6?

Solution

  • All .NET versions 4.0 through 4.6 have the same runtime version number, v4.0.30319. They are not side-by-side, when you install a higher version then it overwrites the earlier version.

    You therefore get RyuJIT if you have 4.6 installed for any project that targets .NET 4.0 and up.

    Projects that target <= 3.5 and don't otherwise override the runtime version with a .config file get the legacy x64 jitter (runtime version v2.0.50727) with no option to use RyuJIT.
