Key Benefits


Q:   Are the original C# files altered in any way?

Your existing code is left completely intact. The new VB.NET project is output to the new location that you specify.

Q:   What version of C# is converted?

We attempt to convert as much as possible and are continually updating the converter to handle newer C# features. However, many new C# features have no VB equivalent so the output will require adjustments.

Q:   Can the converter produce VB6 code?

No - only VB.NET code is produced.

Q:   Do you guarantee a 100% complete conversion?

No - our accuracy is very high, but there will be some adjustments required for all but the simplest conversions. Read the rest of the FAQ to get an idea of a few things that are not converted.
