Maria db stored procedure does not return the data in C#

Question

While using entity framework layer generation for stored procedures in maria db, the columns of stored procedures are not available on calling from C# and the partial class generated does not contain any properties(as in screenshot)

 

 

 

When using complex type as return type, it shows EDM type not supported on function import mapping

 

 

 

Is there a way to fix this? I did a lot research but could not find appropriate solution.

One link says to modify edmx file for the properties manually.

However, it too did not work.

Please help me out on this urgent issue asap
