Fakes Assembly generating error (Cannot implicitly convert type 'int' to 'bool') on AllInternalsVisible

Question

Hello, I'm using VS 2019 Enterprise version 16.11.4 and I'm trying to generate fake assemblies from my own classes of that project or any other assembly (even 3rd party) I have the following errors:

• project compilation failed with exit code 1;
• Cannot implicitly convert type 'int' to 'bool'

And opening the error, it goes to the generated code and I can see that there is a following generated code:

// Some previous code

[assembly: global::System.Runtime.CompilerServices.InternalsVisibleTo("Primavera.Core.Applications, PublicKey=0024000004800000940000000602000000240000525341310004000001000100bfbbcfcfa45d349492d7a837b93e972950a9754029e1973b2f8cf38fabffba0b2380c15581b3a76d1626e4606f4c88ef2f03a0cc245e9390cd884545cf4021b6a177b6a0acef89d296adf0e2c631300b60bca05d38dcfb7318dbbcac767fd905dfdfcc05aea91a5aef718c4f9b5f2cc427671c6a4520f104f51da60f0c68e6c7", AllInternalsVisible = 1)]

// Some next code

And as you can see it tries to generate an int where it should be a bool:

AllInternalsVisible = 1

instead of

AllInternalsVisible = true

I'm using Microsoft.QualityTools.Testing.Fakes version 16.11.230815.

The test project where I'm adding fakes is .NET 5.0 and the assemblies that I'm generating fakes are .NET Standard 2.1

Can you help me fix this issue?

Answer 1

So the only workaround to do is removing the property since it's not implemented in .NET. With that, I can generate the fakes assemblies.

Answer 2

Hi @Kyrylo Yavorenko ,

Welcome to Microsoft Q&A!

Can you create a new project to verify if the error occurs in all projects or not?

Please try to delete the bin, obj and FakesAssemblies folders and recreate the Fakes assembly to check again.
(Please backup the file before any modification, in case we need to roll back.)

Meanwhile, you can also repair your Visual Studio in VS installer > More > Repair..

Anna
