Environment

• Pythonnet version: 2.5.2
• Python version: 3.7
• Operating System: Windows 10
• .NET Runtime: 4.8

Details

• Let's create a simple base class that exposes a property, then create a derived class that overrides the setter, but not the getter (that is supposed to be as it was defined in the base class)

namespacePythonNetTest{publicclassBaseClass{protectedstringname="noname";publicvirtualstringName{get=>name;set=>name=value;}}publicclassDerivedClass:BaseClass{publicoverridestringName{set=>base.Name=value.ToUpper();}}}

• Let's now use the above classes in Python

importclrclr.AddReference("PythonNetTest")fromPythonNetTestimportBaseClass,DerivedClassd=DerivedClass()b=BaseClass()b.Name='BaseClass Name'd.Name='DerivedClass Name'print(b.Name)# okprint(d.Name)# TypeError: property cannot be read

• Here theprint(d.Name) will rise the exceptionTypeError: property cannot be read.
• As a workaround it is possible to useprint(d.GetType().BaseType.GetProperty('Name').GetValue(d)) instead, but it is not one would expect.
