XDR Generation

In order to generate the XDR Files automatically in C# a custom XDR Generator must be used.

You can find the latest working generator here:

You can use that version of xdrgen to regenerate the XDR files from the .x files located from the source of the original API SDK for Horizon.


  1. Install custom XDR generator:
    git clone
    cd xdrgen
    git checkout csharp
    rake install
  2. Regenerate .cs files from .x files:
    cd dotnet-stellar-sdk/
    xdrgen -o=./stellar-dotnet-sdk-xdr/generated -l=csharp -n=stellar_dotnet_sdk.xdr ./stellar-dotnet-sdk-xdr/*.x
  3. Reformat .cs files using dotnet-format:
    dotnet format
