Building PartCover 4 on Vista

Updated again: PartCover Revision 35 includes a patch I provided that builds the same functionality in C#, transiently registering the COM component in HKCU during build, and also providing a --register command line option which is equivalent to the old nCover //r option.

Updated with new complete registry frobbing script, based on actually diffing the before and after states of HKCR when using regsvr32 on the PartCover dll.

Following on from earlier in the week, I pulled the current trunk from SourceForge, and set about building it then putting it to work on some F# code which had caused an earlier version (the most recent available at the end of last year) to balk.

Unzipping the tools (Boost, ATL server) into the appropriate libraries, guided by the include paths (and moving the Debug relative paths to match the Release ones) was trivial, and then it's just a case of firing up MSBuild. Or so I thought.

First hiccup -- it attempts to register the PartCover assembly during the build, and I don't run as administrator by default. So I replaced the

regsvr32 /s /c "$(TargetPath)"

by a manual registry frobbing trick (akin to what NCover 1.5.8 used for its //r option)

"$(ProgramFiles)\FSharp-2.0.0.0\bin\fsi.exe" "$(ProjectDir)\partcover.fsx" "$(TargetPath)"

where partcover.fsx is

This updated per-user registration permits both building and running the PartCover utility without needing full administrator privilege.

So emitting

...\PartCover.exe --target "..\..\..\_Tools\Microsoft Fxcop 10.0\FxCopCmd.exe"  --target-work-dir . --target-args "/q /s /console /f:Tinesware.Recorder.dll /f:Tinesware.Instrumentation.exe /f:Tinesware.Infrastructure.dll /f:Tinesware.Rules.dll /f:Tinesware.InfrastructureTests.dll /f:BaseTests.dll /rule:Tinesware.Rules .dll /o:fxcop.xml /dictionary:..\..\..\CustomDictionary.xml" --include [Tinesware.*]* --include [CSharpTests]* --output PartCoverage.xml

to monitor code coverage when using an FxCop rule written in F#, this reported

which completed cleanly, unlike before, and gave a sane looking output file. There is now obvious code in the system for doing the short branch instruction fix-up, which seems to have resolved the issue I had last time I tried this tool.

So, it really does look good to go for .net 4 code -- and I just have to add hooks to consume that format as well as the old NCover style.
