Testproject VB and C#

Hello Monoteam,

since I have a Debian server version 2.10.2 of mono to mono version 3.10.0 updated, I get the following error message when calling all (* .asmx) files. When you upgrade to version 3.12.1 I get the same error message (see screenshot "VBCompileError").

The update was performed directly on checkout, compile and install from the Mono Git repository.

Meanwhile, I was able to bring it to the point that the error message only appears when a Global.asax file with Visual Basic codebehind is in the application directory. Located the same Global.asax file with C# codebehind in the application directory, function all (* .asmx) files again (see screenshot "CSharpWorks"). Even if the (* .asmx) files with Visual Basic were implemented. If you delete the Visual Basic code behind Global.asax file from the application directory, everything works again.

It seems right at the Global.asax processing in conjunction with Visual Basic to be a problem!

To adjust the problem, I still have a sample project for Visual Basic and C# created (see WebserviceMonoTestProject.zip).
