I ran a Web API that I created with the command dnx web. The service is running fine and I get the result too.
I want to attach the Visual Studio Process to this dnx process and debug the API call. Which process I need to attach to?
Use dnx-watch. this show the dnx process.
It also automatic restart the server after code change
A fast way to debug is to insert Debugger.Launch(); in your code, on the place where you want to start to debug.
It is faster than attach to the right process
dnx-watch can be installed by
dnu commands install Microsoft.Dnx.Watcher

We have for a while been building various web projects with AzureDevops and self hosted build agents.
Today I had to add a new build, consisting of a windows service written in .net core 3.1. This service has to be installed by our customers, so we have to provide it in a friendly installable way. As some of our developers were already used to handle MSI/*.vdproj projects, they added a vdproj into the *.sln to manage that. On a developper machine, this is not a problem even with VS2019: you just have to use the relevant VS studio extension...
But when it comes to building that in a CI/CD context, this becomes a real challenge. I quickly understood that we can't use MSBuild at all for that and found some alternative using directly Visual Studio (devenv)... Inspired by this thread (still opened), I came up with the following command line:
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\devenv" [...]\MySolution.sln /build "Release" /Project MyInstallationProject
This worked fine both on my developer machine and even on the build agent machine. But when I add it into a build pipeline as a command line task, it seems to hang, and after a while I get the following result for the job:
##[error]The job running on agent <MyAgent> ran longer than the maximum time of 60 minutes. For more information, see https://go.microsoft.com/fwlink/?linkid=2077134
What can I do to make it work?
What are the best practices for generating a self installable in a CI/CD context? (Is MSI still relevant? )
As a workaround, you can try to install the extension Build VS Installer and use the task DutchWorkz - Build VS Installer(s) to build Visual Studio Installer Project in Azure Pipelines.
Here are some tickets(ticket1, ticket2) with similar issue you can refer to.
I am new to ASP.Net Core. I have been following a tutuorial. I got to the point at which Javascript code was added to my project. I ran my program, and nothing in the script worked. After adding a few alert() calls, it was apparent that my program was not finding my script. People here and at Reddit suggested I look at the network tab of DevTools. I saw that my program was not able to find any js or css files.
Being an old-school C++/C# developer, I was running the program from a command window by going to the folder containing the executable file and typing the name of the file.
I went back to the beginning. The tutorial directs me to use the dotnet command, which is brand new to me. The first time it tells me to run my program, it tells me to go to the project directory and enter "dotnet run". It just hit me like a ton of bricks that that was what I should have done the first time. I went back to that project, used "dotnet run", and it worked.
So, my question is this: is it possible to run MyProject.exe by itself? If so, how? Copy it into my project folder? Or is the "dotnet run" command the standard way of executing an ASP.Net Core application?
I think it won't work if you directly run it (not sure if we can run MVC project using dotnet-cli (dotnet run will try to load only MSIL to CLR)).
DotNet core console application is different from .net core MVC projects
you can run your project by following ways.
1. Run using visual studio
when you create an MVC application, in the visual studio there will be multiple options to run it, you can choose IISexpress one, it will open in the default browser.
for step by step guide -> https://learn.microsoft.com/en-us/visualstudio/ide/quickstart-aspnet-core?view=vs-2019
2. publish it in IIS
For this you need to ensure few things, like hosting bundle is installed or not, IIS is correctly configured for core application or not.
for step by step guide -> https://stackify.com/how-to-deploy-asp-net-core-to-iis/
3. Use VSCode

I tried to switch from Visual Studio to Visual Studio Code with my CORE project. I can build the C# project in Visual Studio without any problems. When I tried VSCode, I see that I need to define tasks. Fortunately, VSCode offers default tasks definition (it generates tasks.json) for me, so I tried them (there are variants for CORE and .NET, as I understand). But both don't work. I tried to make build from command line, but get error (I translate the error to English, it's not original text):
C:\Program Files\dotnet\sdk\2.1.700\Microsoft.Common.CurrentVersion.targets(3046,5): error MSB4216: can not execute task "GenerateResource", because MSBuild cannot create tasks server with execution environment "CLR4" and architecture "x86" or to connect to it. Verify that, (1) required execution environment and architecture do exist and (2) required executable file "C:\Program Files\dotnet\sdk\2.1.700\MSBuild.exe" exists and can be ran. [D:\prj\...\Test.csproj]
and when I tried to find MSBuild.exe in this folder, I found MSBuild.dll only, no any MSBuild.exe. So, I tried to run it with dotnet after entering this folder - it works. But if I try to call dotnet build or to run it with full path to MSBuild.dll from my project folder, I always get this error. Seems, that dotnet command calls MSBuild.dll multiple times and always hit this problem. May be I should setup some paths or similar. But where to do it (without to break ability to build the project in Visual Studio)? What is the convenient way to build CORE projects in Visual Studio Code? How to build them in command line?
PS. May be all documentation which I found was outdated...
I have a asp.net core project running on a macbook. I'm using visual studio code as my code editor. When I run the project from visual studio code the application boots fine however when I execute dotnet run from the terminal in the project's working directory I get an error that the database hostname value is null. This value is defined in user-secrets. Is there an extra setup I'm missing from the command line?
If it is loading the user secrets only in Development as is normally done, you have to remember to set the environment variable ASPNETCORE_ENVIRONMENT to Development.
How to instruct the build process to run a cmd or PowerShell command/script before or after specific project in .NET Core solution?
I want this command to be executed regardless of the build environment (Visual Studio, dotnet command, or TFS builder).
https://learn.microsoft.com/en-us/dotnet/articles/core/tools/project-json#scripts is the extension point. I did not see the documentation page before asking the question.
