Hello,

if i use the mapping mode "File" there will be thrown an exception at runtime:

System.TypeInitializationException: "The type initializer for 'DefaultXmlMappingProvider' threw an exception."
Inner Exception: ArgumentException: Requested value 'Out' was not found.

Stacktrace:
at System.Enum.TryParseByName(RuntimeType enumType, String originalValueString, ReadOnlySpan`1 value, Boolean ignoreCase, Boolean throwOnFailure, UInt64& result)
at System.Enum.TryParseInt32Enum(RuntimeType enumType, String originalValueString, ReadOnlySpan`1 value, Int32 minInclusive, Int32 maxInclusive, Boolean ignoreCase, Boolean throwOnFailure, TypeCode type, Int32& result)

After spending some hours i figured out the error is caused by "direction" attribute at parameter element.

Example:

<Function Name="ZWT_WS.PKG_PROGRAMMDATEN.PRC_SET_PROGRAMMDATEN" Method="PRCSETPROGRAMMDATEN">
<Parameter Name="P_PROG_ID" Parameter="P_PROG_ID" DbType="NUMBER(12)" />
<Parameter Name="P_FACHL_ID" Parameter="P_FACHL_ID" DbType="VARCHAR2(48 CHAR)" />
<Parameter Name="P_ERGEBNIS" Parameter="P_ERGEBNIS" DbType="VARCHAR2(12 CHAR)" Direction="Out" />
<Parameter Name="P_ERR_TEXT" Parameter="P_ERR_TEXT" DbType="VARCHAR2(2000 CHAR)" Direction="Out" />
</Function>

As soon as a "direction" is given, the error occurs, no matter if direction="In" ... "Out" or "InOut".

Additional Infos:
Provider: Devart dotConnect for Oracle 9.14.1273.0
Devart Entity Developer 6.11.1258
Target Framework: .net5

Can someone please help me?

The bug with using out parameters of a stored procedure, when Mapping Mode is set to File in Model Settings, is fixed. We will notify you when the new public build of dotConnect for Oracle is available for download.

Really great,

big thx to you and your team!

The bug is fixed in v9.14.1312 and higher.
