So I have a simple C# Web API project that I'm attempting to get deployed into Azure. The project builds and runs fine locally (dont they always?!?) but in Azure it fails due to a missing Microsoft.ServiceBus assembly which is used.
The project structure is quite simple:
\
--\Common
----MyProj.common.dll << This uses Microsoft.ServiceBus and has its own packages.config with WindowsAzure.ServiceBus referenced
--\Web
----MyProj.Api << This has an assembly reference to MyProj.common.dll. It doesn't have a reference to WindowsAzure.ServiceBus itself (although I added one to see if it helped, but it didn't)
The output from the Azure deployment script is as follows:

I notice at no point does it attempt to restore the package for the Common assembly - how do I 'tell' Azure to do this? And is this even the issue?
Edit 1
Looking at the deployment script using Kudu, it seems to be doing a solution wide restore, so not sure how/why there is a missing assembly reference:
:: 1. Restore nuget packages
call :ExecuteCmd dotnet restore "MyProj\MyProj.sln"
IF !ERRORLEVEL! NEQ 0 goto error
Thanks

According to your description, your project is .net core project.
You mentioned Servicebus Libriary (WindowsAzure.ServiceBus 4.0.0) is not .NET Core compatible. And the new Libriary, that is a pre-release version, is 100% compatible. We can get more detail here.
We also can find it from another SO thread.
Edit:
According to your comment I update the answer:
I also try to create C# Web API project and deploy to Azure it works correctly on my side.
Please have a try to clean the build and rebuild the project again with a new WebApp.
The following is my detail steps:
1.Create a class libiary project named common and a public ServiceBusHelper class with function GetQueue
2.Create a WebApp project and reference Common.dll and Microsoft.ServiceBus.dll, then change the getvaules function to get queues
public List<QueueDescription> Get()
{
var queueList = Common.ServiceBusHelper.GetQueueList();
return queueList;
}
3.Remove the existed file from the Auzre WebApp during publish the WebApi to Azure
4.Test the WebApp

One of the C# projects in my solution has references to 2 DCOM apps (win32, quite an old DCOM apps).
To successfully build my VS project on PC it is enough to copy 2 exe files and run 2 commands:
XObjectsEx.exe -regserver
SfGbVars.exe -regserver
And then I can run a command to build it:
msbuild SfR2.sln -p:Configuration=Release
Build is successful.
Thus, to successfully build my solution it is enough to do only these steps:
take a new clean PC install (for example: clean VM install with Windows 10/2012/2019 - just any, I tried all of these)
install MS Build Tools 2019
copy 2 exe files + run 2 mentioned commands
run mentioned build command
But(!)...
When I try to do the same under GitHub Actions it reports errors like these:
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(2827,5): warning MSB3284: Cannot get the file path for type library "d6ed8d7e-1780-4747-b41b-a685526cb19b" version 1.0.

In attempt to resolve this problem I added a step to YML file (a step before calling the build itself):
- name: Restore artifacts (SF)
run: build-tools\scripts\InstallArtifacts.ps1 ${{ env.RepoRoot }}/${{ env.OpcPackages_Path }}
working-directory: ${{ env.RepoRoot }}
Where InstallArtifacts.ps1 script executing also following commands:
XObjectsEx.exe -regserver
SfGbVars.exe -regserver
rem ===== .NET registration =====
set NetHome=C:\Windows\Microsoft.NET\Framework\v4.0.30319
set SdkHome=C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.2 Tools
"%SdkHome%\TlbImp.exe" SfGbVars.exe /out:SfGbVars_Net.dll
"%SdkHome%\TlbImp.exe" XObjectsEx.exe /out:XObjectsEx_Net.dll
"%NetHome%\RegAsm.exe" SfGbVars_Net.dll
"%NetHome%\RegAsm.exe" XObjectsEx_Net.dll
In GitHub Actions output I clearly see that all these commands were correctly executed. In output it writes "Types registered successfully" and so on.
Also I checked generated SfGbVars_Net.dll and XObjectsEx_Net.dll with Reflector and confirms - there is a valid .NET wrappers for these DCOM objects.
However that does not affect the build result. It is still reporting the same errors! :-\
Could you please advise - how to resolve this problem?
Why there is such a strange difference in behavior between normal PC and virtual PC under GitHub Actions? So, on PC it is enough to run {app} -regserver command but under GitHub Actions that does not work.

I am using Visual Studio 2019 version 16.11.10. I am trying to do a small C# project that can communicate with an C++ object with functions. What i understand was that i have to use something called C++/CLI wrapper.
I tried to follow this tutorial: redgate - Creating a C++/CLI Wrapper
The project consists of one solution with 3 projects. The three projects are Sandbox (C# project), Wrapper (C++/CLI wrapper project) and Core (C++ project).
A detail about the Core-project is that you have to configure it as Static library (.lib). To do it you will Right-click on the Core-project and select Properties. Under General we select Static library (.lib).
A detail about the Wrapper-project is that you have select “Not Using Precompiled Headers” at Properties->C/C++->Precompiled Headers
I have done some kind of x86/x64 “alignment” for the projects in the Configuration Manager. If i select x86 as solution platform i will set Sandbox to x86, Core to Win32 and Wrapper to Win32. If i select x64 as solution platform i will set Sandbox, Core and Wrapper to x64
I had problems to run the solution on x86. The problem was that Wrapper and Sandbox used different .NET-versions. So now, if both use the same .NET-version (for example .NET 3.1 or .NET 5) for Wrapper and Sandbox, then i can run the solution on x86.
I have problems running the solution on x64. When i run it i get this error:
Microsoft Visual Studio
The debug executable
'C:\Users\Philip\kodning2\vsworkdir\egnaTestProjekt\Solution_CLIExample3\Core\Sandbox\bin\x64\Debug\net5.0\Sandbox.exe'
specified in the 'Sandbox' debug profile does not exist.
OK
I also get these Errors:

How to be able to run this solution as x64? What i am doing wrong?

As Alan Birtles suggested, i post the text from the Output-window:

I am using ->
Visual Studio 2017 Enterprise Edition,
,.Net Framework 4.5.2

In my local system not getting any issues but after pushing changes into release pipeline getting error like below.
Error CS0234: The type or namespace name 'ServiceBus' does not exist

Did I missed anything
Add "Microsoft.Azure.ServiceBus" package to your project:

I tried to understand this tutorial: http://odata.github.io/odata.net/#OData-Client-Code-Generation-Tool
I can generate the proxy without any problems. Just as it is described.
But at chapter "Consume the OData service" it doesn't work. I have named the application and the proxy exactly as shown in the tutorial. How can I make odata available in namespace Microsoft?
Screenshot

I used:
Microsoft Visual Studio 2017 (Trial)
Microsoft.Data.Edm v5.8.3
Microsoft.Data.Odata v5.8.3
Microsoft.Data.Services.Client v5.8.3
System.Spatial v.5.8.3
WCF Data Services 5.6 Tools (are installed)
continuation:
#Evandro Paula:Thank you for your help! I have come a little further thanks to your help. But unfortunately I have not come to the goal yet.
I installed/updated:
Microsoft Visual Studio 2017 (15.7.1) (Trial)
Microsoft.Data.Edm v5.8.3 (I have not found a more recent one)
Microsoft.Data.Odata v5.8.3 (I have not found a more recent one)
Microsoft.Data.Services.Client v5.8.3 (I have not found a more recent one)
Microsoft.OData.Client v7.4.4 (installed)
Microsoft.OData.Core v7.4.4 (installed)
Microsoft.OData.Edm v7.4.4 (installed)
Microsoft.Spatial v7.4.4 (installed)
System.Spatial v.5.8.3 (I have not found a more recent one)
WCF Data Services 5.6 Tools (are installed)
Screenshot of NuGet
Now the results look like this:
Compiling works with Proxy (TrippinProxy.cs), but without Odata example. (Screenshot)
As soon as I copy the code from the tutorial, compiling does't work anymore. (Screenshot)
using System;
using Microsoft.OData.SampleService.Models.TripPin;
namespace TrippinApp
{
class Program
{
static void Main(string[] args)
{
DefaultContainer dsc = new DefaultContainer(
new Uri("http://services.odata.org/V4/(S(fgov00tcpdbmkztpexfg24id))/TrippinServiceRW/"));
var me = dsc.Me.GetValue();
Console.WriteLine(me.UserName);
}
}
}
source: http://odata.github.io/odata.net/#OData-Client-Code-Generation-Tool
Now the Namespace Microsoft.OData is found. But not Microsoft.OData.SampleService (Screenshot)
I need a little example. How can I initialize the proxy and add a product (CreateProduct)? Or how can I get the example from the tutorial up and running?
First, update the packages you mentioned on your question to their latest version. It looks like Visual Studio didn't use the latest version in your case. I'm using Visual Studio 2017 Enterprise Edition (version 15.7.3) for this test.
Microsoft.OData.Client (version 7.4.4)
Microsoft.OData.Core (version 7.4.4)
Microsoft.OData.Edm (version 7.4.4)
Microsoft.Spatial (version 7.4.4)
Once the packages are up to date, you will observe the following build error, which is related to issue https://github.com/OData/lab/issues/80:
Severity Code Description Project File Line Suppression State
Error CS0234 The type or namespace name 'EdmxReader' does not exist in the namespace 'Microsoft.OData.Edm.Csdl' (are you missing an assembly reference?) ODataClient C:\temp\NET\ODataClient\Connected Services\TrippingService\TrippingProxy.cs 510 Active
The resolution for this issue is available at https://github.com/juliopinto15/lab/commit/deb1254301a775eb6771b0bed672dd3f56f37cfe.
Just change the proxy (e.g. TrippingProxy.cs) generated code line below as part of method LoadModelFromString():
return global::Microsoft.OData.Edm.Csdl.EdmxReader.Parse(reader);
to
return global::Microsoft.OData.Edm.Csdl.CsdlReader.Parse(reader);
In my case, I deleted the NuGet cache folder, and it compiles now.
%LOCALAPPDATA%\Nuget\v3-cache
I worked with the same example (TripPinService) and got the same error. It looks like there is an error in the sample.
Instead of:
var context = new DefaultContainer(new Uri(serviceRoot));
You need to write:
var context = new Default.Container(new Uri(serviceRoot));
After that code runs without errors
I'm following tutorial, installed RanvenDB embeeded and write:
public static IDocumentStore archives =
new EmbeddableDocumentStore { DataDirectory = "~/DataStore" };
then I let VS to find where is EmbeddableDocumentStore so and I add:
using Raven.Client.Embedded;
No errors yet and everything looks fine. Then I build:
Archives.cs(10,20): error CS0234: The type or namespace name
'Embedded' does not exist in the namespace 'Raven.Client' (are you
missing an assembly reference?)
Compile complete -- 1 errors, 0 warnings
And now it's error and there is no Embedded...
If I remove package.config and run install Ravendb Embedded again it will become green (with no errors) again but just after I run build...
How to repair it?
(tested different version : same result)
Make sure that you are building for the FULL .NET framework, and not just the client profile.
