Why does C# generate different EXEs for the same source-code?

Question

Every time we recompile our C# application we end up with EXEs with different MD5 signatures. We are recompiling on the same machine, minutes apart. Why doesn't the same source-code yield the same output? Is there a way to fix this?

Answer 1

"So every assembly has:

1. A Timestamp, in two locations
2. A GUID that matched the PDB
3. What appears to be a completely random GUID generated every compile.
4. A counter indicating what the build of the assembly is - generated only in subsequent Visual Studio builds."
