This is an add-in for Fody

Adds an empty constructor to classes even if you have a non-empty one defined.

Introduction to Fody

Usage

See also Fody usage.

NuGet installation

Install the EmptyConstructor.Fody NuGet package and update the Fody NuGet package:

PM> Install-Package EmptyConstructor.Fody
PM> Update-Package Fody

The Update-Package Fody is required since NuGet always defaults to the oldest, and most buggy, version of any dependency.

Add to FodyWeavers.xml

Add <EmptyConstructor/> to FodyWeavers.xml

<?xml version="1.0" encoding="utf-8" ?>
<Weavers>
  <EmptyConstructor/>
</Weavers>

Configuration Options

Exclude types with an Attribute

If for some reason you want to skip a specific class you can mark it with a DoNotVirtualizeAttribute.

Since no reference assembly is shipped with Virtuosity. Just add the below class to your assembly. Namespace does not matter.

public class DoNotVirtualizeAttribute : Attribute
{
}

So your class will look like this

[DoNotVirtualize]
public class ClassToSkip
{
    ...
}

Include or exclude namespaces

These config options are access by modifying the EmptyConstructor node in FodyWeavers.xml

Visibility

The visibility to use when injecting constructors.

Can not be defined with Visibility.

Allowed values: public or family (aka protected)

Defaults to public.

For example

<EmptyConstructor Visibility='family'/>

Making Existing Empty Constructors Visible

Optionally the visibility of already existing constructors can be increased. If this feature is enabled, the visibility of empty-constructors of non-abstract types will be increased to the same visibility as defined by the Visibility configuration (see above).

For example

<EmptyConstructor MakeExistingEmptyConstructorsVisible='True'/>

Will ensure all constructors on non-abstract types will be public.

ExcludeNamespaces

A list of namespaces to exclude.

Can not be defined with IncludeNamespaces.

Can take two forms.

As an element with items delimited by a newline.

<EmptyConstructor>
    <ExcludeNamespaces>
        Foo
        Bar
    </ExcludeNamespaces>
</EmptyConstructor>

Or as a attribute with items delimited by a pipe |.

<EmptyConstructor ExcludeNamespaces='Foo|Bar'/>

IncludeNamespaces

A list of namespaces to include.

Can not be defined with ExcludeNamespaces.

Can take two forms.

As an element with items delimited by a newline.

<EmptyConstructor>
    <IncludeNamespaces>
        Foo
        Bar
    </IncludeNamespaces>
</EmptyConstructor>

Or as a attribute with items delimited by a pipe |.

<EmptyConstructor IncludeNamespaces='Foo|Bar'/>
