The IgnoresAccessChecksToAttribute
is the reverse of the InternalsVisibleToAttribute
- it allows an assembly to declare assemblies whose internals would be visible to it. The attribute class isn't declared in the BCL but is recognized by the CLR (Desktop >= 4.6 and Core), i.e. you can declare it in your code and it would work.
Since there's currently no compiler support for this attribute (I've submitted a PR to Roslyn), this package can be used as a workaround. It generates reference assemblies where all the internal types & members become public, and adds a C# file with the attribute and its instances.
Just add the package and define the InternalsAssemblyNames
property with a semicolon-delimited list of assemblies you need access to.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<InternalsAssemblyNames>AssemblyToGrantAccessTo1;AssemblyToGrantAccessTo2</InternalsAssemblyNames>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="IgnoresAccessChecksToGenerator" Version="0.4.0" PrivateAssets="All" />
</ItemGroup>
</Project>
By default, the build tasks replaces all method bodies with throw null;
. To keep the original bodies, you can specify:
<PropertyGroup>
<InternalsAssemblyUseEmptyMethodBodies>false</InternalsAssemblyUseEmptyMethodBodies>
</PropertyGroup>
