Hello everyone,

My admittedly old version of NCrunch (2.15.0.9 - the latest version I can use with my existing license) which worked fine with VS2013 isn't working with my new VS2015 installation.
Enabling NCrunch displays no visual error message. It seems to be in a limbo between enabled and disabled where I can't even try to re-enable it.

After setting the Log verbosity to "Detailed" I now get the following error in the NCrunch Diagnostic Output window:
"The requested version of the .NET framework, 'Framework46' is not installed on this system"

But .NET Framework 4.6.1 including the SDK is installed.

I tried changing the supported runtime attribute from 4.5.x and 4.6 to 4.6.1 in the NCrunch config files but that didn't help either.

Is there anything else I could be trying to diagnose or even fix this issue?

Thanks in advance,
Markus

Hi Markus,

The version of NCrunch you're using was coded with an incorrect value in the checking for the version of .NET installed. Although this worked fine at the time, when a later version of .NET was later installed the check became invalid and no longer worked correctly.

The correct solution here is to upgrade your version of NCrunch. It might be possible to work around the limitation by dropping back a version or uninstalling later versions of .NET, but I can't confirm this with certainty as I don't have reliable information around which versions are affected or are clashing. I published a fix for this issue as soon as it was reported.

Although we do our best to implement things in a forward compatible manner, combining old versions of NCrunch with newer versions of the .NET platform tooling (i.e. VS, .NET framework, .NET Core, MSBuild, test frameworks) will have a very high chance of exposing you to problems like this one. The platform has been moving very fast for many years, and new changes being made to it are not released as entirely separate compartments that are installed side-by-side (contrary to what the installers would have you believe). We can't warrant that older versions of NCrunch will continue to work if you update your environment. This means you'll either need to freeze your dev environment or keep everything updated.
