Questions tagged [peverify]

PEVerify is a tool that checks if .NET assemblies meet type safety requirements.

The PEVerify tool helps developers who generate Microsoft intermediate language (MSIL) (such as compiler writers, script engine developers, and so on) to determine whether their MSIL code and associated metadata meet type safety requirements.
