Renames a .net assembly/module/namespaces:

• Will change the file name, but also the actual .net assembly name and the matching module name
• Will also rename all namespaces

Usage: RenameAsm.exe <dll to rename> <new name>

Example: RenameAsm C:\my.dll newname will output newname.dll

That requires the dll name and its namespaces to match in the first place: if you have a dll/assembly named AB but its namespace is A.B, it won't match. in that case, either call the tool twice (rename AB to A.B first, then A.B to C.D) or just add a .Replace("AB", "A.B") line in Program.cs.

• ildasm /output:pre.il my.dll disassembles the dll and write the il to a pre.il file
• text replace my with newname and write that to post.il
• ilasm /dll /out:newname.dll post.il

if reassembling fails because embedded resources cannot be found: the disassembling has extracted those resources to the disk (eg. my.someresource.resource). rename these files by hand (newname.someresource.resource), then re-run the tool
