Hi,

I think I have found a bug when trying to compile my VPL as a service when it includes the TextFunctions Activity. The DiagramService.cs source that is code generated is not vaild C#.
To demonstrate, try this very simple VPL:

Where the Data Connection paramerters are:

When you Build->Compile as a Service, the build log shows:

What appears to be the problem is that an invalid "using" statement is generated:

using string = Microsoft.Robotics.Services.Sample.StringHelper.Proxy;

As you can see the reserved work "string" is used as an alias name!

Is there a work-around for this? I am using MSRS 1.5 Released version.

Any help is much appreciated.
