Hi JB,
I am using Mono Cecil version 0.11.3.0 to read .Net Core 3.1 assembly. Here
is the line of code, that is throwing an exception.
var assembly = AssemblyDefinition.ReadAssembly(assemblyPath, new
ReaderParameters { ReadSymbols = true });
Exception:
System.BadImageFormatException: 'Format of the executable (.exe) or library
(.dll) is invalid.'
Can you please help? (Above line of code is working fine for .Net 4.0)
Regards,
Venu
