An Unhandled Exception Occurred: Failed To Execute Weaver

[leszekm1]

Reason: FIPS policy disallows MD5.

Repro:

1. Turn on FIPS security policy in Windows (using LocalSecurityPolicy control panel)
2. Try to weave anything

result:
3>MSBUILD : error : Fody: An unhandled exception occurred:

To be raising issues you should be a patron of Fody. Any issues raised by non Patrons may not be actively triaged, and eventually closed as stale.

I assume that since u are asking about FIPS you are working for a company that has defence clients. If that is the case then all developers at your company (who are using fody) should be patrons

[SimonCropp]

assuming the lack of response means u went a different way. will reopen if u want to proceed

I had to reinstall realm in all projects where uses, and works again!
