.net-core: Equivalent of ILDASM / ILASM

Question

Is there the equivalent of ILDASM / ILASM for the .net-core?

Specifically, I\'m looking for something that runs on Linux (Hence why the .net-core).

Answer 1

Let's 'install' ildasm tool using related nuget-package:

• define RID (Runtime Identifier)

dotnet --info

# execution result
..
Runtime Environment:
 OS Name:     ubuntu
 OS Version:  18.04
 OS Platform: Linux
 RID:         ubuntu.18.04-x64 # <----
..

• download the package runtime.{RID}.Microsoft.NETCore.ILDAsm. For my case it is: runtime.ubuntu.18.04-x64.Microsoft.NETCore.ILDAsm
• unarchive it and extract executable file '/runtimes/{RID}/native/ildasm'
• grant it execution permission and copy to .NET runtime folder (call dotnet --list-runtimes to list runtimes)

chmod +x ildasm
sudo mv ildasm /usr/share/dotnet/shared/Microsoft.NETCore.App/{version}/

• create symlink

ln -s /usr/share/dotnet/shared/Microsoft.NETCore.App/{version}/ildasm ildasm

• run ildasm

./ildasm {path}/project.dll >> {path}/project.il

The same steps are applicable for ilasm.

As an alternate way consider using dotnet-ildasm tool:

# install .net core runtime if required
# sudo apt-get update; \
#   sudo apt-get install -y apt-transport-https && \
#   sudo apt-get update && \
#   sudo apt-get install -y dotnet-runtime-3.0

# find required tool
dotnet tool search ildasm
# output:
# Package ID         Latest Version      Authors      Downloads      Verified
# ---------------------------------------------------------------------------
# dotnet-ildasm      0.12.2              pjbgf        100154                 
# dotasm             1.0.1               DotAsm       434 

# install tool
dotnet tool install -g dotnet-ildasm

Output IL to file:

# go to project folder
cd ../project/bin/Debug/netx.x

dotnet ildasm program.dll -o program.il
