To do what exactly?  Build a project?  The following builds a project in the current directory.

dotnet build 

If you need to change directory then...

CD path\to\the\directory
dotnet build

If you are interested in learning the command switches then scroll down the page and read.

Hi,

I have tried this way

dotnet build -o D:\Test\SampleTestBuild.sln -f .netcoreapp2.2

but getting error as 

Microsoft (R) Build Engine version 16.3.0+0f4c62fea for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

MSBUILD : error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.

any suggestion to fix the error

Answer 5

User475983607 posted

It seems you are not reading reference documentation as -o means output.   Anyway the error message is extremely clear.  There's no project or solution where you are running the command.  

Just CD to solution directly and enter...

dotnet build

This will build to the current version in your project files.

User-474980206 posted

the correct command is:   

dotnet build D:\Test\SampleTestBuild.sln -f .netcoreapp2.2

note the -f <framework> must match what's in the project file. also .netcoreapp2.2 is obsolete. you should fall back 2.1 LTS or upgrade 3.1 LTS

Thank you Bruce and Mgebhard.

i am able to build from command line .but getting below error.

C:\Program Files\dotnet\sdk\3.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(93,5): error NETSDK1013: The TargetFramework value '.netcoreapp2.2' was not recognized. It may be misspelled. If not, then the TargetFrameworkIdentifier and/or TargetFrameworkVersion properties must be specified explicitly.

i have 10 .net core class library projects in my the solutions and all are pointing to .net core 2.2.  all other projects are building properly and only two of them fails with the error message mentioned below.  i have tried to check the project file and i have proper version mentioned.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Configuration.FileExtensions" Version="2.2.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="2.2.0" />
  </ItemGroup>

 </Project>

Hi born2win,

all other projects are building properly and only two of them fails with the error message mentioned below.  i have tried to check the project file and i have proper version mentioned.

Are you sure you use the same command line and only two projects do not work?Actually,when i use your command line it always make such error.It works well by using the following command:

dotnet build D:\Test\SampleTestBuild.sln -f netcoreapp2.2

Best Regards,

Rena

User475983607 posted

The switch is 

dotnet build -f netcoreapp2.2

NOT

dotnet build -f .netcoreapp2.2

Why are you adding the dot?  All you have to do is follow the openly published documentation.  

https://docs.microsoft.com/en-us/dotnet/standard/frameworks

Lastly, if you issue leave the framework version off the build will use the project file framework version.  Have you tried...

dotnet build

... as recommend 3 times now?

Hello Mgebhard,

Thanks a lot for the help. just a build command also worked like charm. so could you please confirm me that if i need to make this work on fresh machine(2012 server- this is going to be build server), just installing .net core SDK proper version(In my case 2.2) will  it be enough?

If you have to ask this question then you are not taking the time to learn the key concepts.  I'm going from your responses above which indicate you are not reading the documentation or the error messages.  Maybe there is a language barrier that getting in the way - I'm not sure.   I know the ASP.NET Core framework docs are globalized and you should be able to read the docs in your native language. 

To answer your question, dotnet build, works exactly as written in the openly published documentation.  The behavior does not change if the CLI command is running on another system. Of course, you must install the ASP.NET core SDK on the build server.

User1489758560 posted

Thank you for the response and i gone through the documentation. I am pretty new to .net core. that's why getting struggle.  the reason why asked this question because of ,in my developer machine, i have all necessary software and sdk's installed.  we have fresh machine as build server and i will have to work with cruise control with ant script to down load the code from svn and make the automatic build. for the .net framework i am able to acheive. but for .net core, i was struggled and initiated this thread.

Thanks a lot for your time on this thread. appreciated all your responses and knowledge sharing.
