Joining layers with SDK c# code

[ThomasMENARD1]

Hi,

i'm developing an addins with ArcGIS pro SDK. I try to join 2 layers with one to many cardinality.

In opened project, i expect that my tool makes join between 2 layers.

Compilated code is ok but when i check layers in project, no joins are etablished.

I find and use some examples:

ProConcepts Geodatabase · Esri/arcgis-pro-sdk Wiki · GitHub 

but i think it do the job but not at client-side

Could someone give me some help or ideas?

Thanks
