<div>
How do you reference? &nbsp;I added it as a project dependency. &nbsp;Tried using below<br />
<br />
using Helper.HelperClass<br />
<br />
I get &quot;type or namespace Helper cannot be found&quot;
</div>


<div>
Figured it out. &nbsp;Had to add reference.
</div>


<div>
<div class="content wysiwyg-content">
An app was written by another developer. &nbsp;App contains multiple projects. &nbsp;One was written in VB and another in C#. &nbsp;Why? &nbsp;I don't know.<br />
<br />
I created a helper class called &quot;FolderLocation&quot; which is in the VB project.<br />
<br />
VbProj -&gt; HelperClass (Folder) - FolderLocation (Class)<br />
<br />
I want to reference the Folder in the C# project<br />
<br />
C#Proj -&gt; DeliveryEmailer (Folder) -&gt; Sender (Class).<br />
<br />
There is a project dependency to the C# Proj in the VB Proj. &nbsp;I can't add a project dependency to the C# referencing the VB Proj because it will create a circular reference.<br />
<br />
Any ideas?

C# - Add a VB reference in C#

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Visual Basic.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
