BI0xxx: binding error messages
E.g. parameters, environment
BI0000: Unexpected error - Please fill a bug report at https://github.com/xamarin/xamarin-macios/issues/new
An unexpected error condition occurred. Please file a bug report with as much information as possible, including:
- Full build logs, with maximum verbosity
- A minimal test case that reproduce the error
- All version informations
The easiest way to get exact version information is to use the Xamarin Studio menu, About Xamarin Studio item, Show Details button and copy/paste the version informations (you can use the Copy Information button).
BI0001: The .NET runtime could not load the {mi.ReturnType.Name} type. Message: {ex.Message}
BI0002: Could not compile the API bindings.
This error is shown when the generator failed to compile the API bindings.
BI0026: Could not parse the command line argument '{argument}': {message}
BI0068: Invalid value for target framework: *.
An invalid target framework was passed using the --target-framework argument. Please specify a valid target framework.
BI0070: Invalid target framework: *. Valid target frameworks are: *.
An invalid target framework was passed using the --target-framework argument. Please specify a valid target framework.
BI0086: A target framework (--target-framework) must be specified when building for *.
This usually indicates a bug in Xamarin.iOS/Xamarin.Mac; please file a bug report with a test case.
BI0087: Xamarin.Mac Classic binding projects are not supported anymore. Please upgrade the binding project to a Xamarin.Mac Unified binding project.
Xamarin.Mac does not support the Classic API anymore, because the Classic API is 32-bit only, and macOS 10.15+ does not support 32-bit applications.
The project must be migrated to a Unified project in order to support 64-bit.
BI0088: MonoTouch binding projects are not supported anymore. Please upgrade the binding project to a Xamarin.iOS (Unified) binding project.
MonoTouch is not supported anymore, because it only supports 32-bit.
The project must be migrated to a Xamarin.iOS (Unified) project in order to support 64-bit.
BI0099: Internal error *. Please file a bug report with a test case (https://github.com/xamarin/xamarin-macios/issues/new).
This error message is reported when an internal consistency check fails.
This usually indicates a bug in the binding generator; please file a new issue on github with a test case.

BI1059: Found * * attributes on the member *. At most one was expected.
BI1060: The * protocol is decorated with [Model], but not [BaseType]. Please verify that [Model] is relevant for this protocol; if so, add [BaseType] as well, otherwise remove [Model].
BI1061: The attribute '{attribute}' found on '{member}' is not a valid binding attribute. Please remove this attribute.
BI1062: The member '*' contains ref/out parameters and must not be decorated with [Async].
BI1063: The 'WrapAttribute' can only be used at the property or at getter/setter level at a given time. Property: '*'.
BI1064: Unsupported ref/out parameter type '{type}' for the parameter '{name}' in {method}.
BI1065: Unsupported parameter type '{type}' for the parameter '{name}' in {method}.
BI1066: Unsupported return type '{type}' in {method}.
BI1067: The type '{type}' is trying to inline the property '{property}' from the protocols '{readonly.DeclaringType.FullName}' and '{writeonly.DeclaringType.FullName}', but the inlined properties don't share the same accessors ('{readonly}' is read-only, while '${writeonly}' is write-only).
BI1068: The type '{type}' is trying to inline the property '{property}' from the protocols '{protocol1}' and '{protocol2}', and the inlined properties use different selectors ({protocol1} uses '{selector1}', and {protocol2} uses '{selector2}.
BI1069: The type '{type}' is trying to inline the methods binding the selector '{selector}' from the protocols '{protocol1}' and '{protocol2}', using methods with different signatures ('{signature}' vs '{signature2}').
BI1070: The type '{type}' is trying to inline the property '{property}' from the protocols '{protocol1}' and '{protocol2}', but the inlined properties are of different types ('{property1}' is int, while '{property2}' is int).
BI1071: The BindAs type for the member "{type}.{member}" must be an array when the member's type is an array. See example binding below.
Correct:
[BindAs (typeof (string []))]
[Export ("stringProp")]
NSString[] StringProp { get; }
Incorrect:
[BindAs (typeof (string))]
[Export ("stringProp")]
NSString[] StringProp { get; }
BI1072: Missing [CoreImageFilterProperty] attribute on {type} property {name}
This error happens when a binding type, decorated with [CoreImageFilter] attribute, has properties that are not decorated with a [CoreImageFilterProperty] attribute. E.g.
[CoreImageFilter]
[BaseType (typeof (CIFilter))]
interface CICustomFilter {
CGAffineTransform Transform { get; }
}
To solve this error you need to tell the CIFilter key that you want to map to the property, e.g.
[CoreImageFilter]
[BaseType (typeof (CIFilter))]
interface CICustomFilter {
[CoreImageFilterProperty ("inputTransform")]
CGAffineTransform Transform { get; }
}
If the property is inlined from a protocol then the [Export] value, prefixed with input, will be used by default. You can override this with by adding the [CoreImageFilterProperty] attribute (e.g. for output* keys).
# BI11xx: warnings
BI1101: Trying to use a string as a [Target]
BI1102: Using the deprecated EventArgs for a delegate signature in ., please use DelegateName instead
BI1103: '*' does not live under a namespace; namespaces are a highly recommended .NET best practice
BI1104: Could not load the referenced library '*': *.
BI1105: Potential selector/argument mismatch [Export ("*")] has * arguments and . has * arguments
BI1106: The parameter * in the method . exposes a model (). Please expose the corresponding protocol type instead (.I*)
BI1107: The return type of the method . exposes a model (). Please expose the corresponding protocol type instead (.I*).
BI1108: The [Protocolize] attribute is applied to the return type of the method ., but the return type (*) isn't a model and can thus not be protocolized. Please remove the [Protocolize] attribute.
BI1109: The return type of the method . exposes a model (). Please expose the corresponding protocol type instead (.I*).
BI1110: The property . exposes a model (). Please expose the corresponding protocol type instead (.I*).
BI1111: Interface '' on '' is being ignored as it is not a protocol. Did you mean '*' instead?
BI1112: Property * should be renamed to 'Delegate' for BaseType.Events and BaseType.Delegates to work.
BI1113: BaseType.Delegates were set but no properties could be found. Do ensure that the WrapAttribute is used on the right properties.
BI1114: Binding error: test unable to find property: * on *.
BI1115: The parameter '' in the delegate '' does not have a [CCallback] or [BlockCallback] attribute. Defaulting to [CCallback].
BI1116: The parameter '' in the delegate '' does not have a [CCallback] or [BlockCallback] attribute. Defaulting to [CCallback]. Declare a custom delegate instead of using System.Action / System.Func and add the attribute on the corresponding parameter.
BI1117: The member '*' is decorated with [Static] and its container class * is decorated with [Category] this leads to hard to use code. Please inline * into * class.
[NullAllowed] should not be used on methods, like '*', but only on properties, parameters and return values.
The [NullAllowed] attribute should not be allowed on methods but it could break existing binding projects.
Historically it was used on property setters. However using the attribute on other methods can be misleading, e.g. should it apply to all parameters, the return value... and its presence/action can be misinterpreted in code reviews leading to binding bugs.
To fix this warning use the [NullAllowed] attribute only on parameters, properties or return values.
