Receiving this error in TeamCity. We are using .Net 4.5 in the project, and we are NOT using Silverlight. I HAD to install .Net 4.7 on the server because I received a Postsharp error requiring it the first time I built on there.

Open in IDE

    According to the error message exception is thrown by PostSharp 6.0.25. Could you please check whether you have different projects referencing different PostSharp versions in your solution? We recommend to unify all projects to one PostSharp version in this case.

    The exception itself tells us that one of the referenced assemblies in your project must target 'Silverlight,Version=v4.0'. Could you please confirm whether this is true?

    In any case this is caused by a bug on our side. We have filed an internal issue (#16514) and we'll get back to you once the fix is released.
