How I do a sign an assembly that has already been built into a dll specifically flute.dll

Question

The reason I want to sign the dll is because I want to add it to the Global Assembly Cache. The assembly is a css parsing engine written in Java and ported to J#. I use VS20

Answer 1

The Strong Name tool can re-sign an existing assembly, using the -R option. However, from what I understand, the assembly has to be previously signed or delay-signed... not sure you can use it with an unsigned assembly, but you can give it a try
