Cannot find any entry point error

Debugging 2 identical custom boards with SCM20260N modules. Getting the dreaded Cannot find any entrypoint and likely because nothing is being deployed.

Nothing seems to get deployed when I click run. I’ve done a reflash of the firmware and erased the application area. I have the modules enabled for extended flash etc. Both exhibit the same issue.

Build Output shows this.

Followed but this in the output window

Found debugger!

Create TS.

Loading Deployment Assemblies.

Resolving.

The debugging target runtime is loading the application assemblies and starting execution.
Ready.

Cannot find any entrypoint!

Done.

Waiting for debug commands…

The program ‘[17] TinyCLR application: Managed’ has exited with code 0 (0x0).

Strange thing is that I was able to deploy and debug a basic program before I started to write the meat of the code.

I now have 1 board working but unable to debug it. :frowning:

This happened to me, make sure that the the main project is set as the startup project in visual studio

Did you add any other assembly as reference?
