Mono Method Body Replacement Samples

Prerequisites

To run the tests you will need to:

Build a runtime with the MonoMetadataUpdate property set to true: /p:MonoMetadataUpdate=true.
Put the hotreload-delta-gen command line tool somewhere on your PATH.

Build the tool with dotnet publish --self-contained -r <RID> and then add the publish/hotreload-delta-gen directory to your PATH. If you don't want to add it to your PATH, you can set the HotReloadDeltaGenFullPath msbuild property in DeltaHelper.targets to the full path name of the published executable.

The tool, runtime changes and samples should work on Mac and Linux. Windows might work, but it hasn't been tested.

Build the runtime with the /p:MonoMetadataUpdate=true option.

Both Debug and Release configurations should work.

For desktop:

build.sh -s Mono+Libs /p:MonoMetadataUpdate=true

For WebAssembly:

Make sure EMSDK_PATH is set (see workflow)

build.sh --os browser

For Apple targets:

build.sh --os MacCatalyst -s Mono+Libs

build.sh --os iOSSimulator -s Mono+Libs

For console (desktop):

make CONFIG=Debug publish && make CONFIG=Debug run

The output from run should print an old string, apply an update and then print a new string

For browser (WebAssembly):

make CONFIG=Debug && make CONFIG=Debug run

Then go to http://localhost:8000/ and click the button once or twice (the example has 2 updates prebuilt)

For Apple targets:

for ios simulator

make run-sim

for Mac Catalyst

make run-catalyst
