Getting the following error message in the Errors tab of 2 of our servers in the NCrunch Distributed Processing window

The file in question does exist, so not sure why it's coming up with this. Both are running VS2017 15.3.1 (latest). Project is a full .NET framework 4.6.2 system (not .NET core)

NCrunch version 3.11.0.3 (preview release from another thread)

Code:

Very early indication looks like it has fixed it on one grid node but not on another. Are there any logs we can send over to help?

Early indications were wrong I'm afraid, and it's failing intermittently on all build servers. We're being tough on you this month aren't we!

Can you confirm whether the grid nodes are able to run tests when using NCrunch as a VS package? My feeling is that this is either a missing dependency on the grid node that isn't being properly handled, or its dependency data that isn't translating to the grid node properly.

Hi Remco,

Sorry for the delay in getting back to you with this. I don't think this error stops the GridNodes from running the tests itself, as our tests still seem to run fine whether on the GridNode or using NCrunch in Visual Studio.

If this message does give you trouble, it may be worth upgrading to the full release version of 3.11 (released just yesterday). This included a few resolution fixes over the preview version you've been running.

Have updated to the latest version, and also enabled FusionLog for this and get slightly better stack trace:

The really strange thing is that that file does exist on both the client and the server. I'm adding the NuGet package to that project and seeing if that helps

Sorry, it looks like I may need to ask for a code sample that can reproduce this :(

This is going to be a tough one to figure out. The CLR is having an internal issue while trying to load this assembly. My experience with these sorts of problems suggests that trying to get specific information about why the reference is failing to load may be extremely difficult, perhaps even impossible without extensive experimentation.

Can you confirm for me the context of this exception? Does it only appear on the grid nodes? Does your local machine work OK?

[img=https://ledgerscope-my.sharepoint.com/personal/matthew_ledgerscope_com/_layouts/15/guestaccess.aspx?docid=0b9b3f64ced0c4b8aa8de0f4e84c84999&authkey=AbtIU707wlgB909LCm5tCbo]Error[/img]

That's where we're seeing the error. The grid node does process tests afterwards (the exception usually happens in bunches of 3, and then doesn't happen for a while). Locally we don't get any errors listed (although I'm not sure where the local equivalent of that view would be).

I'll see if I can decompose enough of it to put together a code sample, but it may end up being the whole project

NCrunch is continuing to function in this case because the error is happening only during the analysis task, when tests are discovered.

The analysis task is always run on each grid node after a build. Because only one task is actually needed to get the true list of tests, the redundancy allows the engine to continue. As long as your local machine or at least one grid node can report a result without the error appearing, the tests are discovered and they can be farmed out to the grid.

So it's still bad, because it means that you have nodes that are unable to discover the tests. The rest of the grid compensates.

I would suggest looking at install state differences between the nodes to examine whether the nodes that don't work are lacking something (perhaps an SDK?).

Solved it!

That was our only VS Test Project that didn't have a reference to the NuGet package System.Runtime. I think our migration to VSTest v2 might have caused this issue, and NuGet/Microsoft have started doing weird stuff where you need to have references to stuff that is already built into the framework

Thanks for your help
