I just changed a *.csproj file to generate the XML documentation in a Docs folder tree under the main solution directory:

<PropertyGroup>
<Rwv37SolutionDirectory>$(MSBuildProjectDirectory)\..</Rwv37SolutionDirectory>
<Rwv37SolutionDocsDirectory>$(Rwv37SolutionDirectory)\Docs</Rwv37SolutionDocsDirectory>
<Rwv37ProjectDocsDirectory>$(Rwv37SolutionDocsDirectory)\$(MSBuildProjectName)</Rwv37ProjectDocsDirectory>
<DocumentationFile>$(Rwv37ProjectDocsDirectory)\$(MSBuildProjectName).xml</DocumentationFile>
</PropertyGroup>


That's working fine insofar as the documentation files are generated in the place I want them to be. So, for example for the "Core" project, Core.xml is generated in the Docs\Core directory, which itself is directly in the solution directory (i.e. a level up from the project directory).

However, every time I open the solution in VS, a new nCrunchTemp_* directory is created within Docs. The directory is empty, and seemingly never gets deleted without manual intervention. So, for example, I just cleaned it all up manually, then opened/closed the solution three times. The Docs directory now contains:

d---- 10/12/2021 4:15 PM Core
d---- 10/12/2021 4:31 PM nCrunchTemp_0061d108-8910-4b78-9fd1-05add17c0cef
d---- 10/12/2021 4:20 PM nCrunchTemp_827aef2c-59fb-4989-a0a2-71d100c3ae14
d---- 10/12/2021 4:23 PM nCrunchTemp_cecd3a7f-524e-435b-9dae-9bc4146610bb


None of the nCrunchTemp_* directories have anything in them, and as far as I can tell they will never go away unless I manually delete them. And the next time I open the solution, a fourth will be created.

I am using VS 2019 16.11.2 and NCrunch 4.9.0.8.

Why would NCrunch be creating these directories there? Why don't they ever get cleaned up? Can I do something to have them automatically cleaned up? Or, preferably, to not be put there in the first place? Thanks.

Hi, thanks for sharing this issue.

When NCrunch loads the project, it creates a renamed clone of the project with some minor modifications.

My expectation here is that you're using a package or toolset that is taking the name of the project and using this to generate files when at least part of the build for the project is done.

Can you tell me more about the project involved and whether you have any 3rd party packages installed in it? If you can share the project XML with me, this would be ideal.

Thanks for these details. Could you try making the 'GenerateDocumentationFile' property conditional inside its own PropertyGroup to see if this solves the problem? Example below:

<PropertyGroup Condition="'$(NCrunch)' != '1'">
<GenerateDocumentationFile>true</GenerateDocumentationFile>
</PropertyGroup>

Poked around a little more, and found:

(1) If I take the GenerateDocumentationFile property out completely, it still happens.

(2) However, if I put it back in and explicitly set it to false, it does not happen.

That (the PropertyGroup Condition one) seems to have done the trick. Thank you!
