Change Assembly Version in a compiled .NET assembly

Question

Simple question... is there a way to change the Assembly Version of a compiled .NET assembly?

I\'d actually be fine with a way to change the Assembly File Version.

Answer 1

Old topic but here are my 5 dimes...

1. Disassemble

   ildasm my.exe /output:my.il /metadata

2. Edit my.il to change version information. There are several places to look into:

   • major:minor:revision:build - usually one occurrence
   • major.minor.revision.build - several occurrences. The string is found in the comment section after the actual line. The version is a hexadecimal value in a byte array. Example:

.custom instance void [mscorlib]System.Reflection.AssemblyFileVersionAttribute::.ctor(string) = ( 01 00 07 35 2E 31 2E 33 2E 30 00 00 ) // ...5.1.3.0..

3. Edit my.res to change version information. Double click and edit with visual studio. Pretty straight forward procedure.

4. Assemble

   ilasm my.il /res:my.res
