Setup default RunCommand in case MSBuild project RunCommand is undefined

[alexfdezsauco]

Sometimes a project RunCommand can't be resolved

Such situation causes that process launch failed.

When?

When?

Good question. I have a project configuration where the project instance RunCommand property is empty, but not sure why.
I started to get the Cannot start process because the file name has not been provided error when I try to hosted it on tye. So, make that Tye could survive to such situation by trying with a default RunCommand.

I know this will sound stupid but does the project build ?
The behavior of tye when the udnerlying service is project and it fails on internal dotnet restore or dotnet build can be "strange" and ends up in an error that look like yours
because the binary could not be built, then there was no file provided to run the process

Also can you share a repro somehow ?

[alexfdezsauco]

@tebeco Yes, it builds. I will try to extract the repo (but it will take longer than the time it took me to find this problem). With this default RunCommand, I'm was to continue to work and host the solution on Tye.

Well, now I noticed, that it requires a second tye run. Let me check again.

[alexfdezsauco]

I will close this because it is not a definitive solution. It requires to tye run in both the RunCommand is emby but in the second one it runs.

[alexfdezsauco]

@tebeco @davidfowl Well I set <TargetFramework>netcoreapp3.1</TargetFramework> instead <TargetFrameworks>netcoreapp3.1</TargetFrameworks> and RunCommand got the expected value.

So, if TargetFramework is undefined even when TargetFrameworks have values the RunCommand will be empty at least on my configuration.

Welcome the the club, see #564

Good news is that you just need to wait for this to be merged :
#567

also you can ALREADY edit you yaml by adding buildProperties:

name: app-with-targetframeworks
services:
- name: multipletargetframeworks
  project: MultipleTargetFrameworks/MultipleTargetFrameworks.csproj
  buildProperties:
  - name: TargetFramework
    value: netcoreapp3.1
