The dotnet ildiff compares the IL difference between two .NET assemblies. Simply send the assemblies path as parameter and as a result you will get the diff.
The project was created as a global CLI tool, therefore you can install with a single command:
dotnet tool install -g dotnet-ildiff
Notice that for the command above to work, you need .NET Core SDK 2.1.300 or above installed in your machine.
dotnet ildiff <ASSEMBLY1_PATH> <ASSEMBLY2_PATH>
dotnet ildiff <ASSEMBLY1_PATH> <ASSEMBLY2_PATH> <-o|--output>
dotnet ildiff <ASSEMBLY1_PATH> <ASSEMBLY2_PATH> <-i|--item>
dotnet ildiff <-h|--help>
-i
Filter results by method and/or classes to be disassembled.
-o
Define the output file to be created with the assembly's IL.
Output IL diff to the command line:
dotnet ildiff myassembly1.dll myassembly2.dll
Filter results by method and/or classes to be disassembled, showing the result in the command line:
dotnet ildiff myassembly1.dll myassembly2.dll -i ClassName
dotnet ildiff myassembly1.dll myassembly2.dll -i ::MethodName
dotnet ildiff myassembly1.dll myassembly2.dll -i ClassName::MethodName
Define the file to be created with the output:
dotnet ildiff myassembly1.dll myassembly2.dll -o disassembledAssembly.il
