@jronay & @vinnyrose: could you try what happens if you delete the VS MEF Cache?
It is located at: %localappdata%\Microsoft\VisualStudio\15.0\ComponentModelCache

[SabotageAndi]

I just recognized that there could be more than 1 ComponentModelCache folder to delete:

I have them in multiple folders of different VS versions. Please delete it in all VS version folders.

I had the same issue. For me, updating VS helped (i had 15.3.3 when the issue was reproducible). On 15.5.7, the problem was not present.

[jronay]

@SabotageAndi it may take a few days. I have a demo of SpecFlow on Monday, and can't risk breaking my setup again. It is a production laptop. :)

[SabotageAndi]

I put the old releases on GitHub. Use the 2017.1.10

[jronay]

@SabotageAndi Thanks. Can you include a link to the old releases please?

[SabotageAndi]

[SabotageAndi]

@jronay Is it working for you now?

Any ideas

[SabotageAndi]

@mp-marc For which version of Visual Studio do you want to install the extension?

[mp-marc]

Hi @SabotageAndi

My version of Visual Studio is 2017, 15.2

Thanks

[jronay]

@SabotageAndi For now I am using version 2017.1.6 and this is working. Were any changes made to the .12 version?

[mp-marc]

@SabotageAndi I have tried all versions of the extension from 2017.1.6-2017.1.9 (inclusive), and all give the same error as above.

Any help would be greatly appreciated.

@jronay btw what version of visual studio are you using

Many thanks

[SabotageAndi]

@mp-marc VS2017 15.2 was released in May 2017. We are currently at 15.5 and 15.6 will be released soon.
Here is the changelog: https://docs.microsoft.com/en-us/visualstudio/releasenotes/vs2017-relnotes

Please update your Visual Studio.

[jronay]

@SabotageAndi I updated Visual Studio to 15.5.7 and it is working fine now.

[jronay]

@SabotageAndi That is the SpecFlow 2017.1.12 Extension version is working fine with Visual Studio version 15.5.7

[vinnyrose]

@SabotageAndi everything fine when VS is updated to latest.

[SabotageAndi]

@jronay & @vinnyrose: cool
So we know, that you need the latest VS version that the extension gets installed without problems.

Solved for me => I am closing this issue.

Same issue with 15.6.6 VS2017
Install Error : Microsoft.VisualStudio.ExtensionManager.MissingTargetFrameworkException: The extension 'SpecFlow for Visual Studio 2017' requires a version of the .NET Framework that is not installed.

Tried cleaning up MEF directory, no luck.

[SabotageAndi]

@vijay-rbt The VS Extension for VS 2017 needs .NET 4.6. According to the error message, you don't have it installed. No idea how that is possible.

[vijay-rbt]

@SabotageAndi - i do have .NET 4.6, (4.6.000079) that's why error is so weird and i am unable to circumvent it.

[SabotageAndi]

@vijay-rbt Open an issue via the feedback client in Visual Studio at Microsoft. I don't think we can help you here.
