Inserts and Count() works fine Any ideas?

LiteDB is standalone only for .NET Full… for NetStandard some packages are required by framework

Sorry for bothering you @mbdavid, but after few hours of investigation I found out that somehow System.Reflection.TypeExtensions package was not installed. After i created clean project and added LiteDB, package manager also installed all dependencies correctly, and for now all is working. Sorry for my lack of knowledge.
