SharpDevelop integration

[ddur]

So far it was possible just to drop new binaries in Sharp Develop \bin\tools\OpenCover[x86|x64].
It does not apply any more.

When I copy Release binaries and run, coverage.xml is empty, no error messages.

Running Debug binaries reports message:
Committing...
No results, this could be for a number of reasons. The most common reasons are: 1) missing PDBs for the assemblies that match the filter please review the output file and refer to the Usage guide (Usage.rtf) about filters. 2) the profiler may not be registered correctly, please refer to the Usage guide and the -register switch.

Sharp Develop generated command:
"[......]\SharpDevelop\bin\Tools\OpenCover\OpenCover.Console.exe" -register:user -mergebyhash -target:"[......]\bin\Tools\NUnit\nunit-console-x86.exe" -targetdir:"[......]\Source\Test\Project\bin\Debug" -targetargs:"\"[......]\bin\Debug\Project.dll\" /xml=\"[......]\Source\Test\Project\bin\Debug\Project-TestResult.xml\" /pipe=\"df535cbf-c30c-4549-ba92-4a67d2bc53e7\" /run=\"ProjectTest\"" -output:"[......]\Source\Test\Project\OpenCover\coverage.xml" -filter:"+[Solution]Namespace1* +[Solution]Namespace2* "

I do not know what is changed in OpenCover (profiler?) after 4.5.2506.1
Maybe problem has to do with /pipe=\"df535cbf-c30c-4549-ba92-4a67d2bc53e7\" option used in command?

I tried all releases from and including 4.5.2506
https://github.com/OpenCover/opencover/releases/tag/4.5.2506
https://github.com/OpenCover/opencover/releases/tag/4.5.3207
https://github.com/OpenCover/opencover/releases/tag/4.5.3427
https://github.com/OpenCover/opencover/releases/tag/4.6.166
https://github.com/OpenCover/opencover/releases/tag/4.6.181-rc
https://github.com/OpenCover/opencover/releases/tag/4.6.192-rc

All above works as expected except most recent one:
https://github.com/OpenCover/opencover/releases/tag/4.6.210-rc

What is the pipe option? A throwback from the PartCover days?

The command line parser should fail if an unrecognized parameter is supplied.

[ddur]

1. No, is not 'pipe'. It works same when 'pipe' removed.
2. It is not command line parser. If command line parser fails, OpenCover would stop immediately with exception. Here everything looks fine, tests are performed, until end, when coverage.xml is empty.

@sawilde
AFAIK, SharpDevelop runs OpenCover as child process.
Maybe problem is here #282

@ddur, could you also check a CI build before 4.6.210? This one (4.6.206) is right before merging the feature you suspect, and this is a build with the changes.

[ddur]

Thanks @molnargab
Build https://ci.appveyor.com/project/sawilde/opencover/build/4.6.205 works
Build https://ci.appveyor.com/project/sawilde/opencover/build/4.6.206 not
Problem is somewhere here #345 sawilde@f9bf9f9

[ddur]

Well, looks like builds after 4.6.205 do not work outside build environment.
No single one Zip distribution package (after 4.6.205) contains CrashReporter.NET.dll
Latest MSI distribution (just installed and tested), contains CrashReporter.NET.dll, but it does not work too.

This is not only SharpDevelop issue!
