Description monobugz 2012-08-22 18:45:25 UTC
Cannot .Compile() a pretty big (51k) xml schema generated by entityframework. Works fine on .net but Mono gets into infinite recursion in series of .CheckRecursion() methods. 

Unfortunately i failed to isolate a smaller .xsd for testcase, sorry. Original schema .xsd and xml-test.cs testcase are attached.

Compiling CSDL Schema Version 3

This issue also occurs when compiling (validating) the official CSDLSchema Version 3 which is packed with the Entity Framework (System.Data.Resources.CSDLSchema_3.xsd). This makes using Entity Framework with model first impossible.

CSDL Schema Version 1 + 2 however validates without error.
