Q# : QDK Errors - visual-studio-code

Question

I've recently tried to install the QDK via the VSCode extension in my Windows 10 Desktop and VSCode wasn't able to find the Microsoft libraries even after I was able to execute the code by the dotnet run command on the terminal. The code was the sample project code described in the create new project part of the tutorial. I also didn't have .NET SDK so I installed it but it seems to be working fine. In computers I got problems all the code, all related to not finding the namespaces.
namespace QuantumRNG {
open Microsoft.Quantum.Canon;
open Microsoft.Quantum.Intrinsic;
open Microsoft.Quantum.Measurement;
open Microsoft.Quantum.Math;
open Microsoft.Quantum.Convert;
operation GenerateRandomBit() : Result {
using (q = Qubit()) {
H(q);
return MResetZ(q);
}
}
operation SampleRandomNumberInRange(max : Int) : Int {
mutable output = 0;
repeat {
mutable bits = new Result[0];
for (idxBit in 1..BitSizeI(max)) {
set bits += [GenerateRandomBit()];
}
set output = ResultArrayAsInt(bits);
} until (output <= max);
return output;
}
#EntryPoint()
operation SampleRandomNumber() : Int {
let max = 50;
Message($"Sampling a random number between 0 and {max}: ");
return SampleRandomNumberInRange(max);
}
}

Answer 1

Do you see any error messages in the output console?
To see the output console select "View: Toggle Output" (Ctrl + Shift + U) and select "Q# Language Extension" from the drop down list.
If the drop down list doesn't show "Q# Language Extension" then it probably means that the language-server that gets downloaded on first run is still downloading, so give it a minute or so (depending on your internet connection).

Answer 2

I think I also had the same problem. The .Net SDk which you have downloaded automatically creates a path in the environment variable by the name "%USERPROFILE%.dotnet\tools" so delete this and add "C:\Program Files\dotnet\sdk" or copy the path of dotnet SDK from the drive where you have installed dotnet and create a new environment variable under user variable. This might solve your namespace problem.
