How to remove magic strings from AppHost Program.cs

[swegele]

Sorry if dumb question, but I couldn't figure it out. I'm on Aspire preview 5.

ALL the examples use magic strings in the apphost and then in the various actuall projects.

var myredis = builder.AddRedis("myredis");
var myorleans = builder.AddOrleans("myorleans")
    .WithClustering(myredis )
    .WithGrainStorage("mygrainstore", myredis );

I tried creating a constants project which is referenced by XX.AppHost but that doesn't seem to work, probably because it thinks I'm adding it to the orchestration :-)
Any ideas of how to get rid of these magic strings which is use-able from all the projects including XX.AppHost.

EDIT:
A little wonky - but I just tried "Add existing item" on the XX.AppHost project and pointed to the Constants.cs file and used "Add as linked".
This adds a link to the constants file as if it is in the project.
Seems to compile and work fine so maybe I answered my own question
:-)

If you want to do that, then you need to set IsAspireProjectResource="false" on your project reference:

aspire/playground/mongo/Mongo.AppHost/Mongo.AppHost.csproj

Line 17 in f71c302

<ProjectReference Include="..\..\..\src\Aspire.Hosting.Azure\Aspire.Hosting.Azure.csproj" IsAspireProjectResource="false" />

Shared sources also work.

Aha I figured there was a trick! That will come in handy. Thanks @davidfowl !

P.S. My "add existing file as link" trick worked nicely because all the constants can be marked "internal" which adds just a little obfuscation. Beats sharing a bunch of public const values in an assembly that will get distributed along side projects.
