The first time i launch my tests, the package works perfectly. But then if i relaunch my tests i get:

/usr/lib/dotnet/sdk/6.0.116/Microsoft.Common.CurrentVersion.targets(4812,5): error MSB3027: Could not copy "/home/user/.nuget/packages/ephemeralmongo6.runtime.linux-x64/1.0.0/runtimes/linux-x64/native/mongodb/bin/mongod" to "bin/Debug/net6.0/runtimes/linux-x64/native/mongodb/bin/mongod".

A workaround is to run dotnet clean each time before running tests

Hi @henaff , the MongoDB executables are copied at build time and a few minutes ago I've changed the CopyToOutputDirectory value from Always to PreserveNewest, so that might help to prevent copying files for nothing (see 1.1.2).

However, it your mongod process in your bin/ directory is still being used, it means that the process was not correctly disposed. You must dispose the IMongoRunner that you get when calling MongoRunner.Run, and try to reuse it as much as you can in your test project.
