Conflicting configuration settings were specified for property 'MyProperty' on type 'MyType'. MaxLength = 100 conflicts with MaxLength = 200

[IT-CASADO]

Hi,

i have a big problem on using Complex Types on my entities.
I created a small repro for my issue. You can find it as an attachment.

The VS Solution is attached so that following Package Manager command can be executed without any errors.

Add-Migration -Name Initial -Force

You can see the generated output in 201605111247310_Initial.cs.
I configured a MaxLength for all strings to 50 (see MyContext.cs).
Then I configured one of the sub property (PropB) of MyEntity.First (this is a complex type) to have a max length of 100.

Up to here all works as expected.

Now I'm trying to configure property "PropB" for MyEntity.Second to have a max length of 200.

For that uncomment line 18 in MyEntityConfiguration.cs and run the following command again:

Add-Migration -Name Initial -Force

Now I get this error:

Conflicting configuration settings were specified for property 'PropA' on type 'ComplexTypeWithStringLength.MyComplexType' MaxLength = 100 conflicts with MaxLength = 200

I don't understand why!? Is this a bug?

Regards,
Daniel

@IT-CASADO This is a limitation of EF, some property facets need to be stored in C-Space and EF doesn't have a way of configuring a particular usage of a complex type. So you can only specify different S-Space facets like ColumnName or ColumnType
