Q: Is the original VB.NET project altered in any way?
Your existing code is left completely intact. The new C#
project is written to the new location that you specify.
Q: Do you guarantee a 100% complete conversion?
No. Our accuracy is very high, but there will be
some minor tweaks required in all but the simplest projects. Read the rest
of the FAQ to get an idea of a few things that are not converted.
Q: Does Instant C# convert VB6 projects to C#?
No. The most effective and safest way to get from VB6 to
C# is to use an upgrade tool (3rd party or the VS 2008 Upgrade Wizard) on your
VB6 code, and then use Instant C# on the resulting VB.NET code.
Q: How are classic VB.NET string functions handled?
By default, Instant C# converts them to
the closest .NET string method. You also have the option of leaving them as
calls to the Microsoft.VisualBasic namespace, if you are depending on some
of the strange quirks of the classic VB string functions.
Q: Is VB code within ASP.NET files converted?
For now it is, but conversion of code within ASP.NET files is not supported after April 2019.
Q: What are the most common adjustments necessary after conversion?
If the VB project did not have 'Option Strict On' set, then you'll
likely have a number of cases where different types are compared
with each other - these may need adjustment.
Although most On Error GoTo statements are
converted, some elements of classic VB unstructured error
handling (On Error Resume Next, On Error GoTo -1, etc.) are not
converted by Instant C#. These statements are marked as a
Some references to the Microsoft.VisualBasic
namespace are left intact (the code will run via
references to the .NET Microsoft.VisualBasic namespace). You have the
option of converting many of the .NET Microsoft.VisualBasic
methods which have .NET equivalents, but in general Instant C#
does not rewrite functionality in the .NET Microsoft.VisualBasic
Files with vbhtml extensions (using 'Razor' syntax) are not converted.
Universal Windows Platform (UWP) apps
(formerly 'UAP', 'Metro', 'WinRT', or 'Windows Store') are
converted, but the converter cannot discover type information which
is inside .winmd files. There are a couple of possible work-arounds,
but they will not work consistently for all users. This means that
there will be more manual adjustments required for Universal app
