Xsd.exe generates duplicate attributes when run on OFX2 schema
Using the command line:
"xsd.exe" "OFX 2.1.1 schema/OFX2_Protocol.xsd" /c /namespace:OFX /nologo"
C # original source file fails to build with these errors:
D:\blah\OFX2_Protocol.cs(19,6): error CS0579: Duplicate 'System.CodeDom.Compiler.GeneratedCodeAttribute' attribute
D:\blah\OFX2_Protocol.cs(20,6): error CS0579: Duplicate 'System.SerializableAttribute' attribute
D:\blah\OFX2_Protocol.cs(21,6): error CS0579: Duplicate 'System.Diagnostics.DebuggerStepThroughAttribute' attribute
D:\blah\OFX2_Protocol.cs(22,6): error CS0579: Duplicate 'System.ComponentModel.DesignerCategoryAttribute' attribute
D:\blah\OFX2_Protocol.cs(23,6): error CS0579: Duplicate 'System.Xml.Serialization.XmlTypeAttribute' attribute
D:\blah\OFX2_Protocol.cs(24,6): error CS0579: Duplicate 'System.Xml.Serialization.XmlRootAttribute' attribute
A similar XSD schema that I copied from the OFX2 schema then trimmed down to the useful bits I wanted generates a C # file that builds just fine but has all the same attributes as the full C # schema representation.
Any idea why? Is the OFX schema broken? Is xsd.exe fixed? Is C # broken? Am I broken?

Ok, this answer is taking a long time ...
I just ran into the same problem. The problem was not foo.cs, but foo.designer.cs. You need to remove duplicate attributes in the second class.
C # should either allow duplicate attributes across partial classes, or fix the xsd to omit attributes in all but the .cs file.

I had the same problem (same "duplicate attributes" problem) with different schemas. the reason was caused by two xsd schemas (2 generated files) and in each of them I had the same item "type" but with different definitions. renaming one of the types to another name solves the problem
