Mono 4


Update the Mono stack in Fedora from 2.10 to 4.*


Current status

Detailed Description

Support for Mono versions 3.0 and 2.10 has been discontinued. No further development of bug fixing is planned for those branches. Mono 4 is the active branch and has many improvements. See upstream notes

Mono requires itself to build. The Mono version 2.10.8 currently included in Fedora is too old to build version 4 that requires at least version 3.4. At the moment on copr we use monolite, a little version of mono compiler shipped in the tarball for first build time.

We have two options to upgrade:

Steps for Bootstrapping

  • The Monolite binaries are included in the Mono tarball which is provided by upstream. see also
    • Monolite is a minimal binary distribution of mcs. This is the compiler that is able to build the rest of Mono.
  • In the spec file, we usually delete all dlls and executables before the build section.
  • For the bootstrap, we would once keep the monolite binaries.
  • After Mono has been built for all primary and secondary architectures, and for Epel, we enable the deletion of the monolite binaries again in the spec file.

Benefit to Fedora

Fedora aims to showcase the latest in free and open source software - we should have the most recent release of Mono 4.0.1

It will have the ability to run cross-platform applications that require compatibility with Microsoft. Net Framework 4.5


  • Proposal owners:

Update mono spec and build in copr and/or koji until is ready.

  • Other developers:

See Upgrade/compatibility impact and Dependencies section

  • Release engineering: None
  • Policies and guidelines: None

Upgrade/compatibility impact

Mono 4 includes most of the features of Mono 2.10 and Mono 3 branch.

The profiles 2.0, 3.5 and 4.0 will not be build any more in favor of profile 4.5

Many packages may need to be revised, updated or rebuilt because Mono 4 require that all application use target 4.5. In general is a simple task to sed .sln, .cproj, configure,,, Makefile,, for use mcs instead gmcs and change profile < 4.5 to 4.5. The files to sed change depending in what form is distributed the sources. In most off the cases only configure files need sed. A few package work without changes like gnome-subtitle or pinta

The fixes is work in progress on and

How To Test

Interested testers do not need special hardware. Take a given Mono application and test it against the Mono at this copr repo and verify it works:


Any issue will be reported in github or

User Experience

User should note speedy improvement running Mono applications.

Some applications will have features only supported if used Mono 4
