This signature holds all of the IL of the method, the EH table, the locals table, and each token (other than type references) in those tables is replaced with an index into a local stream of signatures. Those signatures are simply verbatim copies of the needed metadata to describe MemberRefs, TypeSpecs, MethodSpecs, StandaloneSignatures and strings. All of that is bundled into a large byte array. In addition, a series of TypeSignatures follows which allow the type references to be resolved, as well as a methodreference to the uninstantiated method. Assuming all of this matches with the data that is present at runtime, the fixup is considered to be satisfied.
