Diagnostics Warning STRDIAG001

The [DataContract] is not valid for the type '{0}'. Expected is a public/internal Accessor.

Explanation

The DataContractAttribute can only be applied to public/internal type. Any lower access will cause STRDIAG001 on the target type.

Example: private inner class

The following example generates STRDIAG001:

using Stride.Core;

public class STRDIAG001
{
    [DataContract]
    private class InnerClass { }
}

Example: file scoped class

using Stride.Core;

[DataContract]
file class STRDIAG001
{
}

Solution

To resolve the warning, increase the accessibility of the type to public/internal or remove the DataContractAttribute.
