Piece of template code from shared library marked as uncovered while it is definitely covered

The abstract template code in the shared library is not executed; it's only the instantiations that are, so what you have observed is the expected behaviour. One instantiation takes one...

`dotnet test /p:AltCover=true /p:AltCoverInPlace=true` results in System.IO.IOException: The process cannot access the file 'C:\src\testprj\bin\Debug\net8.0\AltCover.Recorder.g.dll' because it is being used by another process.

This is an unfortunate effect of the way that, on Windows, at least, file locks can take some appreciable time to release even after the process that took them out...

`dotnet test /p:AltCover=true /p:AltCoverInPlace=true` results in System.IO.IOException: The process cannot access the file 'C:\src\testprj\bin\Debug\net8.0\AltCover.Recorder.g.dll' because it is being used by another process.

The message is emitted only after a number of attempts have failed; so I've added some mitigations - tightening the scope of the use of the recorder file, so the...

Release 8.8.21 mitigates the likelihood of the issue, and improves the resulting error message if the file cannot be promptly deleted.

Assuming sufficiently resolved.

Coverage collection at the end from .acv files is taking significant time

Exactly what is written to the `.acv` visits file(s) will depend on how you are driving AltCover. In most use cases, each visit is written eagerly, with "classic" mode and...

Coverage collection at the end from .acv files is taking significant time

Finally got around to doing some performance testing, and with a program dominated by a tight loop - ```fsharp let n = 1000 for i in 1..n do for j...

Coverage collection at the end from .acv files is taking significant time

Up front, I don't think I can offer any quick wins with this, except that if you're getting many (hundreds or more) visits per location, there is some speed-up to...

Coverage collection at the end from .acv files is taking significant time

Something throwing an exception should be filed as a separate issue. And could you please post the log file with the exception trace in.

Coverage collection at the end from .acv files is taking significant time

As well as the discussion here (and in #225) regarding the use of `--single` and `--defer`, it is worth noting in the comparisons with `coverlet` that that tool takes a...
