Hi Richard,

Thanks for reaching out!

Can you try adding Octopack to your Packages.config file manually and then forcing an update of all the nuget packages in your project?

<package id="OctoPack" version="3.0.67" targetFramework="net46" developmentDependency="true" />

Let me know how that goes.

Thanks

Hello,

Thanks for the quick response. Adding OctoPack to the packages.config file did not work; but updating all packages highlighted the real issue. The packages.config file had the xml namespace attribute in the packages element:

I think this might be valid xml but it seems to break the package manager. I removed the attribute and OctoPack installed.

Thanks for the help.

Richard

P.s. You’ll probably hear from me again has I try to set up our CD work flow.

Glad to hear you sorted it out Richard!

You know where to find us already. If possible just try to keep each question on its own thread (so people can find them easily).

Cheers
