Key Benefits


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 first upgrade to VB.NET, 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.NET code within ASP.NET files converted?

No. ASP.NET files, including vbhtml files ('razor syntax') are not converted.

Q:   What are the most common adjustments necessary after conversion?
