I have just recently upgraded to VS 2017 from VS 2013.
This involved moving up a patch level with NCrunch and installing via the 2017 installer.

On VS 2013 everything was working ok, but on VS 2017 I am finding that most projects fail to load, with the following exception:

Code:
System.InvalidOperationException: No process is associated with this object.
   at System.Diagnostics.Process.EnsureState(State state)
   at System.Diagnostics.Process.EnsureState(State state)
   at System.Diagnostics.Process.get_Id()
   at nCrunch.Core.ProcessManagement.ExternalProcessManager.(ExternalProcess )
   at nCrunch.Core.ProcessManagement.ExternalProcessManager.(ProcessorArchitecture , ProcessLoadParameters )
   at nCrunch.Core.ProcessManagement.ExternalProcessManager.LoadExternalProcess(ProcessLoadParameters parameters, GridClientId client)
   at nCrunch.Core.BuildManagement.BuildProcessLauncher..()
   at nCrunch.Common.PerformanceTracking.PerfTracker.TryTrackActivity(String name, Action activity)
   at nCrunch.Core.BuildManagement.BuildProcessLauncher.(Action`1 , ProcessorArchitecture , GridClientId , BuildSystemParameters , IList`1 )
   at nCrunch.Core.BuildManagement.BuildProcessLauncher.AnalyseComponentBuildInExternalProcess(ComponentLoadParameters parameters, IList`1 customEnvironmentVariables)
   at nCrunch.Client.ComponentLoader.SnapshotComponentLoader.(ProcessorArchitecture , String )
   at nCrunch.Client.ComponentLoader.SnapshotComponentLoader.CreateComponentFromXml(FilePath projectFilePath, ParsedBuildXml projectXml, FilePath solutionFilePath, String[] additionalFilesToIncludeAtSolutionLevel, Boolean isLoadedFromFile, VisualStudioVersion vsVersion, ComponentUniqueName componentName, TaskSettings componentTaskSettings, Exception parseException, String targetFramework)


Our company has SRP (Software Restriction Policies) in place, which when temporarily disabled allow the project to load and build in NCrunch without issue.

I can add local SRP rules to make an exception for NCrunch, but profiling using Process Monitor I was unable to determine exactly what executable/path is being blocked, and i'm not sure if this is the correct solution to the problem.

Can anybody shed any more light on this issue, or point me in the right direction for further debugging?

Thanks,

On examination of the event log I found multiple events like the following:

Code:
Access to C:\Users\{username}\AppData\Local\NCrunch\BuildSystem\840\VS2017\nCrunch.BuildHost462.x86.exe has been restricted by your Administrator by the default software restriction policy level.
Access to C:\Users\{username}\AppData\Local\NCrunch\BuildSystem\8952\VS2017\nCrunch.BuildHost462.x86.exe has been restricted by your Administrator by the default software restriction policy level.


This looks like the source of the problem.
I can add a SRP path rule in for C:\Users\{username}\AppData\Local\NCrunch\BuildSystem\*\VS2017\*.exe, however is this what is normally recommended?
Did something change between the VS 2013 and VS 2017 extensions that causes this issue?

Yes, your analysis here is correct. Under VS2017, NCrunch's build integration works differently because MSBuild assemblies aren't installed in the GAC. This means that the buildhost needs to have dynamically constructed binding redirections to the MSBuild assemblies so that build tasks can find them. To make this work, NCrunch sandboxes the build executable.

I have no solid experience with SRP rules, but I believe your solution is the right one. NCrunch needs to be able to launch .EXEs from the above path, otherwise it won't be able to build your projects.

Ok thanks.

I have implemented the above rule, and NCrunch looks to be working correctly.

I have the same problem, but unfortunately I cannot apply any rules to my local machine. Is there a way to change this directory? I tried to set up "Workspace base path" in my NCrunch Configuration, but it doesn't have any effects.

Hi, I'm sorry to hear this is the case.

The directory itself is hard-coded. It's normally safe for software to assume that it can store data in its own directory under your local user profile. Without any way to adjust your SRP, I'm not sure how to solve this problem for you. NCrunch needs to have a transient location to store these files, and the workspace base path isn't the appropriate place.

I contacted my security department and they were able to add exception in the rules on my local machine. That solved all my problems. Thanks.

So I just had this problem again after upgrading to 2019.
Came to the forums to search for an answer and came across my own post!
I modified the SRP above to replace VS2017 with a * wildcard and everything is working now.

We have actually included a change in the latest release to allow you to change the directory used by NCrunch for its build hosts.

If you set your 'Workspace base path' configuration setting to somewhere else (that is allowed under SRP), you hopefully won't have this problem again.
