Hi,

I'm having a weird error after updating visual studio 2019 community from v16.4.5 to 16.5. Even a fresh install of the engine will no longer build. I'm getting the errors listed below. The build doesn't fail until the end of compiling all modules:

I have not changed or updated anything on the Unreal Engine-side of the code, and I've been reading that some users of Epic's latest release (UE4.24.3) are having compilation errors as well. This error occurs during a build of UE4.sln, sourced from Epic's github repo. 

Seeing as Microsoft doesn't have archives of installers for VS Community, only Enterprise and Pro, I'm kind of suddenly stuck here because I can't just uninstall 16.5 and reinstall 16.4.5 (which is the last working version I was on before the update).

Any insight into this would be helpful, Thanks!

Hi there!
After update to Visual Studio 16.5.1 (Community Edition 2019), when I add a new page to project, a page is showed with the message: "Waiting for Intellicense to finish initializing...", but this process/task never ends.
I need to close the page and reopen it.
Is there a way to fix that?

Best regards!

Ciro

I have made a program with C in Visual Studio which has been working fine. Lately, I have been doing some minor updates, and suddenly dozens of errors show up when compiling, but without showing any error in my own code. I have absolutely no idea why this happens and what to do about it, and therefore need some help. Here is the error messages:

I am developing a Windows Forms Project including a Setup/deployment project.

Each time, I finish a new version, I
- rebuild and create *.msi file for install, fx pgm_7-0.msi - version 7.0
- save a copy of the project source code

Then I increase all version numbers:
- Assembly version to 7.1
- file version to 7.1
- publish version 7.1 (just in case)
- setup project version 7.1, upgrade productcode
- Setup project properties output file name to pgm_7-1.msi

This has worked fine for years - even through the project has lived in VS2008 -> VS2010 -> VS2013 and now VS2017

But as I went from 7.2 to 7.3 /7.4 it still produces a pgm_7-2.msi.

Looks like the output file name hangs in pgm_7-2.msi no matter what I do.

Any explanation ?

My program is a shell namespace extension. The situation is similar to the following case in Stackoverflow forum. But the problem only happened in VS, When I switched to another program, everything was OK again.

Hello,

I have visual studio installed on my system for both C# and C++ and I am able to open both c# and C++ solution files and run them on my visual studio.However I do not have have option to create any C# projects I can edit in the already created project but I cannot create a new one. Also at the same I have option to create a C++ project and also edit them. 

Could some one tell my why it is so or probably the solution to resolve this. ? This will help me resolve this issue.

Thanks in Advance for Your Help,

Hi,

I’m new to Visual Studio and have an issue with Forms and partial classes.

I have a form with has a lot of code behind it. To make it easier to navigate I’ve created a new C# file and put in it the partial class for the form, I’ve then moved some of the forms routines I created into the new c# file.

The problem with this is that when I add the partial class to the new c# file, the c# file then open another form when I double click on it – so now I have two forms??

This is the process I’m taking:

• Create a new solution, and add a form – Called Form1 (I’ve added a button to the form).

• As my form has a lot of code, I would like to create a partial class of Form1 so that I can put some of the code in a different file – its easier to navigate this way (so I'm told), so I add a new Class which creates Class1.cs

• To change Class1 to a partial class of Form1, I copy the code:

“Public partial class Form1 : Form” from Form1.cs and replace the line “class Class1” in Class1.cs

I also add “Using System.Windows.Forms” to Class1.cs.

• Now when I double click on Class1.cs it open a blank form (though I can get to the code by double clicking on the blank form).

So I now appear to have two forms in my project, the original one for Form1.cs and the new blank one for Class1.cs.

The main reason I am doing this is because the code I have in Form1 is becoming very long and difficult to navigate and so I’d like to split the code into different files. From a previous post on the internet someone said that partial classes where the best way of doing this.

I'd appriciate some advise on why I'm getting two forms - its not a big deal as I can still run my code, its just confusing...

Thanks.

I have installed VS Code and the Python plug-in. I have setup a virtual env using Anaconda and added django to this env.
I can select the Virtual env from the drop down list or via the option at the bottom of the screen. A new terminal then runsconda activate <env_name>. However when i try to run the Python website, i get an error that django is not installed.
If i run conda info --envs it shows that the environment is set to the Anaconda base env. despite me changing it.
if i manually run conda activate <env_name> nothing changes.
Why is VS Code not picking up the right virtual environment?

I added Unosquare.WiringPi to my to a Visual Studio Forms project. But I am unfamiliar with C programming and the way it's declared and initialized in the Visual Studio "Blink" project doesn't work in my Visual Studio Forms project. Can you tell me if is possible to use it with my Forms project, and if so how?

I am very familiar with Visual Basic. Do you know if it is possible to use Unosquare.WiringPi with Visual Basic?

Perhaps a better question would be to mention that the programmer did not include any testing and the code was so created to virtually eliminate maintenance or testing by anyone other than -- and possibly even by -- the creator.

I'm using the latest release of the Visual Studio 2019 Community Edition.  I'm building a console application that uses the Intel Math Kernel Library to do linear algebra calculations.  I successfully used them in the past but have not used them recently.

The application builds successfully but throws an unhandled exception when I call one of intel functions that I have not had issues with in the past.  The debugger output indicate that is has something to do with KernelBase.dll and that it may be some kind of a path problem.  I have updated the installs of Visual Studio and the MKL library the to  latest versions and I am still having the problem.

The exception is thrown when I call the MKL functionLAPACKE_dgetrf.  

Thank you in advance for your help.
