问题
I have 3 project in my C# solution.
- Signatures
- Structures
- Tests
Signatures has public and internal interfaces. Also it has
[assembly: InternalsVisibleTo("Structures")]
[assembly: InternalsVisibleTo("Tests")]
in AssemblyInfo.cs of.
Structures has public and internal classes and
[assembly: InternalsVisibleTo("Tests")]
in AssemblyInfo.cs of.
Tests has next source:
<packages>
<package id="Moq" version="4.2.1409.1722" targetFramework="net45" />
<package id="NUnit" version="2.6.4" targetFramework="net45" />
<package id="NUnitTestAdapter" version="1.2" targetFramework="net45" />
</packages>
as NuGet packages in packages.config.
I wrote some unit test for internal interface from Signatures and internal class from Structures. Run, and had next result: exception:
Type Signatures.InterfaceX is not visible to DynamicProxy. Can not create proxy for types that are not accessible. Make the type public, or internal and mark your assembly with [assembly: InternalsVisibleTo(InternalsVisible.ToDynamicProxyGenAssembly2)] attribute.
Seems logical. I added [assembly: InternalsVisibleTo("InternalsVisible.DynamicProxyGenAssembly2")] to assembly info of Signatures and Structures projects. Run, and had next result: exception:
Type 'Castle.Proxies.IReminiscenceableDataTableProxy' from assembly 'DynamicProxyGenAssembly2, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is attempting to implement an inaccessible interface.
This was to help, but didn't. Only change exception message.
How to fix my problem?
回答1:
The suggested fix message uses a const/static field for the assembly name:
[assembly: InternalsVisibleTo(InternalsVisible.ToDynamicProxyGenAssembly2)]
You used a string which does not correspond to the assembly name:
[assembly: InternalsVisibleTo("InternalsVisible.DynamicProxyGenAssembly2")]
Change it to:
[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")]
You can see the actual assembly name (which should appear in InternalsVisibleTo) in your error message:
Type 'Castle.Proxies.IReminiscenceableDataTableProxy' from assembly 'DynamicProxyGenAssembly2 (...)
