[Rado8267]

I have installed newest version of converter in VS 2017 Enterprise. If I want convert VB.NET code to C# I get this error message:

That is all. Can you help me?

same issue here... are we missing some core dlls?

Hi, thanks for posting. It looks like a dependency upgrade in a recent release broke support for VS2017 - I can reproduce this issue on VisualStudio.15.Release/15.9.21+28307.1064

For now, you'll need to either use VS2019, or uninstall the extension, close all visual studio windows, then install version 8.01 from here

If there's any reason you can't use VS2019 I'd be interested to know why (is it a licensing thing?) since I'll be considering dropping support for VS2017 in 6 months

Hi,

the solution I was trying to use it, is "technically super-outdated" with a big mess of c# and vb projects, old node.js modules and such. Classic entropy death scenario,. Issue is, the solution just doesn't compile/work under vs2019 and "upgrading" is too much of an effort..
Licensing is not an issue, but the use-case for those kind of "refactoring tools" are IMHO mainly quite old (and mostly messy) solutions, where you don't really want to "touch" the overall build process and mess around with upgrading to a newer VS release. just my 5 cents on it...

[GrahamTheCoder]

Makes sense, thanks for the info. I would like to keep VS2017 going as long as possible for the reason you describe, but it's pretty hard to stay compatible while making use of the great new tools available.

I've put in a tentative fix, would you mind trying it? There's a CI build artifact you can try here: https://icsharpcode.visualstudio.com/icsharpcode-pipelines/_build/results?buildId=1188&view=results
Again, uninstall the extension, close all VS windows, then install the vsix from the "published artifact"

[dreamworks]

it's working now under vs2017.. thx a lot!

[GrahamTheCoder]

Great thanks for confirming!
