I get an error adding assemblies to Visual Studio 2022:

one or more errors occurred
a task was canceled
a task was canceled
a task was canceled
a task was canceled

Any help would be appreciated...

PS! I was able to add the assemblies by editing the project file.

C:\Program Files (x86)\Rebex Components R6.7\bin\net-6.0\Rebex.Imap.dll


C:\Program Files (x86)\Rebex Components R6.7\bin\net-6.0\Rebex.Common.dll


C:\Program Files (x86)\Rebex Components R6.7\bin\net-6.0\Rebex.Mail.dll


C:\Program Files (x86)\Rebex Components R6.7\bin\net-6.0\Rebex.Networking.dll

But this should not be the preferred way in my opinion.

I just tried this with a newly-created VS 2022 project (a .NET 6.0 console app), and I am unable to reproduce this issue. Where exactly do these error appear, and which version of VS 2022 do you use?

This is the message I get when calling a method that uses the Rebex Secure Email components after adding them in project file as mentioned in OP:

Could not load file or assembly 'Rebex.Imap, Version=6.0.8314.0, Culture=neutral, PublicKeyToken=1c4638788972655d'. The system cannot find the file specified.

In Visual Studio 2022 I cannot add them. This is the info:

And I get an error dialog which says:

This is very annoying I hope we can find out what is wrong.

Ok. I discovered that if I unreferenced the other references, then added rebex, then added the others I was able to add the assemblies from rebex.

However I get this error as stated earlier when trying to call a method that references i.e: imap dll, i get this error:
Could not load file or assembly 'Rebex.Imap, Version=6.0.8314.0, Culture=neutral, PublicKeyToken=1c4638788972655d'. The system cannot find the file specified.

Ok, this last problem. After I did a Clean and build again, the assembly was found at runtime, and everything now works.

A lot of different problems but at least I now can focus on what's important. Code.

Thanks for the update!
I'm afraid this problem is not related to Rebex assemblies - it loooks like one of Visual Studio's quirks. See the results of the corresponding Google search:
https://www.google.com/search?q=visual+studio+"a+task+was+canceled"+errors

Usually, cleaning and rebuilding helps. Restoring packages might help as well. Restarting Visual Studio is another commonly-used workaround.

If there was any indication that this is a Rebex issue, we would look into it, but we need to be able to reproduce the issue first.
