ASP.NET Core Environment variables not being used when debugging through a Service Fabric project -

-

when creating asp.net core app environment variable called aspnetcore_environment=development set , when debugging see ihostingenvironment set development.

the problem when use same project in solution set service fabric environment variables don't seem injected , ihostingenvironment returns "production".

how can resolve this?

note: i've set breakpoint in startup class observe ihostingenvironment variable.

reference answer: https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-manage-multiple-environment-app-configuration

i ran same issue default template. following similar duncan's answer 2 important differences: 1) not have change template code within service, , 2) ihostingenvironment set.

first, add aspnetcore_environment variable <codepackage> element of packageroot\servicemanifest.xml file of application service:

<codepackage name="code" version="1.0.0">   <entrypoint>     <exehost>       <program>myservice.exe</program>       <workingfolder>codepackage</workingfolder>     </exehost>   </entrypoint>   <environmentvariables>     <environmentvariable name="aspnetcore_environment" value=""/>   </environmentvariables> </codepackage>

as in duncan's response, there 2 changes you'll make applicationmanifest.xml of service fabric application project. first, setup parameter (variable) can modified when applicationparameters files substituted based on way deploy project. then, add environmentaloverrides section servicemanifestimport element. results of 2 additions this:

<parameters>   <parameter name="myservice_instancecount" defaultvalue="-1" />   <parameter name="aspnetcoreenvironment" defaultvalue="" /> </parameters>  <servicemanifestimport>   <servicemanifestref servicemanifestname="myservicepkg" servicemanifestversion="1.0.0" />   <environmentoverrides codepackageref="code">     <environmentvariable name="aspnetcore_environment" value="[aspnetcoreenvironment]" />   </environmentoverrides> </servicemanifestimport>

finally, can add in proper values in individual applicationparameters files:

<parameters>   <parameter name="myservice_instancecount" value="-1" />   <parameter name="aspnetcoreenvironment" value="development" /> </parameters>

at point, can remove variable service's properties - debug environmental variables.
