aync not preserved when converting a c# async method to vb

static async Task<Uri> CreateProductAsync(Product product)

Current conversion to VB:
Private Shared Function CreateProductAsync(product As Product) As Task(Of Uri)

Correct conversion to VB:
Private Shared Async Function CreateProductAsync(product As Product) As Task(Of Uri)

select keyword not converted correctly from C# to VB

See the differences in query; the C# was the original, the VB the generated. Note the C# "select p" is converted over with no "select", presumably because select is a VB keyword:

property = (from t in containerType.GetInterfaces()
let p = GetTypeDescriptor(t).GetProperties()
.Find(propertyName, true)
where p != null
select p

[property] = (From t In containerType.GetInterfaces()Let p = GetTypeDescriptor(t).GetProperties().Find(propertyName, True) Where p IsNot Nothingp).FirstOrDefault()

C# has where p != null select p, VB has Where p ISNot Nothingp, where the p is pushed against the "Nothing" keyword.

Math and String functions

I am currently working on a engineering piece of software and convert old vb6 to c# 4.6

1. I have had quite a few times that I needed to add Math. in front of the converted c# code eg.

Log => Math.Log

This might be the case with other Math functions

2. I have had to change the statement of counting the length of a string and other string functions as follows

Len(string) => string.Length
Mid(string, int, int) => string.Substring(int, int)

This could be the case with other string functions

a Client reported that the batch page of the converter does not work

It should be either removed or redirected:

This is the page:

Thanks in advance.

'Handles MyBase.Load' should be appended to event while converting Page_Load method from to

I was converting 'protected void Page_Load(object sender, EventArgs e)' from C# to VB and it returned me 'Protected Sub Page_Load(sender As Object, e As EventArgs)' where as expected was 'Protected Sub Page_Load(sender As Object, e As EventArgs) Handles MyBase.Load'. This caused me couple of hours to detect as I was considering that conversion is 100% correct. I understand and appreciate this converter and understand this is evolving product, Hence thought should report same to you guys. Keep it up with your good Work.

cshtml/ vbhtml.

Would be great a converter for cshtml to vbhtml and vice versa.

converting from c# to Vb-

public ActionResult MyNextAction()
return Redirect(Request.Referrer.ToString());

Converts to-

public ActionResult MyNextAction()
return Redirect(Request.UrlReferrer.ToString());

using != if

Using gZipStream = New GZipStream(memoryStream, CompressionMode.Decompress)
Converts to
using (gZipStream == new GZipStream(memoryStream, CompressionMode.Decompress))

Correct one would be
using (var gZipStream = new GZipStream(memoryStream, CompressionMode.Decompress))

array of anonymous type ( to c#)

Dim plans() = {New With {Key .ParentId = 100000010, Key .ChildId = 100000011}, New With {Key .ParentId = 100000012, Key .ChildId = 100000013}}
It should be converted so
var plans = new[] { new { ParentId = 100000010, ChildId = 100000011 }, new { ParentId = 100000012, ChildId = 100000013 } };
Now converted into a nonworking crap
[] plans = {
new {
ParentId = 100000010,
ChildId = 100000011
new {
ParentId = 100000012,
ChildId = 100000013
