 - Fixed query parameters type mapping for arrays. [#3354](https://github.com/microsoft/kiota/issues/3354)
 - The lock file now contains the relative path to the description in case of local path. [#3151](https://github.com/microsoft/kiota/issues/3151)
+- Fixes a bug where query parameters would be missing in CSharp for ebc clients. [#3583](https://github.com/microsoft/kiota/issues/3583)
 - Fixed bug where base64url and decimal types would not be generated properly in Java.
 - Fixed bug where symbol name cleanup would not work on forward single quotes characters [#3426](https://github.com/microsoft/kiota/issues/3426).
