fsproj files in dotnet-core projects - f#

When creating new projects with .net-core (dotnet new -l F#), the projects are created with a project.json file and no fsproj file. However, it is my understanding that an fsproj file is needed in order to get intellisense.
Are there any tools for generating an fsproj file from a project.json file?
I am interested in a solution that works both in Linux and Visual Studio as I use both equally for fsharp.

If you open project.json in Visual Studio 2015 with update 3, it will create an xproj file for the project.
I'm not aware of a way of doing this in linux.
However, as far as I know you don't need an fsproj file to get intellisense.

I found projekt useful for creating and manipulating .fsproj files. However, it will not automatically convert your project.json for you.

Stop Visual Studio 2019 from automatically adding files in project folder

I have a .NET Core 3 project in Visual Studio 2019. When I copy and paste a file, through Windows Explorer, into the project folder, Visual Studio automatically includes the file into my project, which I do not want to happen. Is there a setting to disable this feature?
Starting from VS 2017 project format in .NET has changed. You need to add <PropertyGroup> tag at the top of your .csproj file:
<PropertyGroup>
<EnableDefaultItems>false</EnableDefaultItems>
</PropertyGroup>
Here is the complete answer to your question:
In Visual Studio, why are all files automatically part of my C# project?
Well, you can modify the known project file (.csproj for c# project), by customize the items include path that satisfied your include files specifically.

No sln file in MVC project. Any way to generate?

I am supposed to take over a project which is MVC based. in the source code folder, I see all the required files except the sln file. Is there a way to generate the sln file for MVC project? Will it work as expected?
If your project has the .csproj file, then open the .csproj file with Visual Studio, then when you close VS it will ask you to save a .sln file.

F#, Visual Studio 2017 and dotnet new

To create a .NET class library from the command line, you can run the script
dotnet new classlib
Do that in a clean folder, and it will create a csproj file that can then be opened in Visual Studio 2017.
However, run the script
dotnet new classlib -lang f#
in a clean folder, and the fsproj file that is subsequently create cannot be opened in Visual Studio 2017. The error message reads
The imported project "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Sdks\FSharp.NET.Sdk\Sdk\Sdk.props" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.
I have searched for clarification of this issue, and it appears that there is work ongoing to fix it, but I wondered in the interim if there are any add-ins I can install to get this working immediately.
The latest preview releases of Visual Studio and .NET Core support loading .fsproj projects, apparently.
See this comment on the GitHub issue:
Closing this now, as these projects load with 15.3. The current way to use them:
Download VS 2017 Update 3 Preview 3 (or a further preview if it's released and you're reading this)
Download the latest CLI/SDK from here: https://github.com/dotnet/cli/tree/release/2.0.0#installers-and-binaries
(Yes, the .NET SDK is independent of VS. You will also need this to get .NET Core 2.0 support in VS 2017 Update 3 Previews).

The default XML namespace of the project must be the MSBuild XML namespace

I cloned the ASP.NET Core SignalR Repo locally, and try opening the solution from within the following environment.
IDE
Microsoft Visual Studio Enterprise 2015
Version 14.0.25431.01 Update 3
Microsoft .NET Framework
Version 4.6.01055
DOT NET CLI
λ dotnet --info
.NET Command Line Tools (1.0.0-preview2-1-003177)
Product Information:
Version: 1.0.0-preview2-1-003177
Commit SHA-1 hash: a2df9c2576
Runtime Environment:
OS Name: Windows
OS Version: 6.1.7601
OS Platform: Windows
RID: win7-x64
I end up seeing a lot of these kinds of error messages:
..\Repos\SignalR\src\Microsoft.AspNetCore.SignalR\Microsoft.AspNetCore.SignalR.csproj
: error : The default XML namespace of the project must be the
MSBuild XML namespace. If the project is authored in the MSBuild 2003
format, please add
xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to the
element. If the project has been authored in the old 1.0 or
1.2 format, please convert it to MSBuild 2003 format. ..\Repos\SignalR\src\Microsoft.AspNetCore.SignalR\Microsoft.AspNetCore.SignalR.csproj
I want to know how to fix this the correct way.
The projects you are trying to open are in the new .NET Core csproj format. This means you need to use Visual Studio 2017 which supports this new format.
For a little bit of history, initially .NET Core used project.json instead of *.csproj. However, after some considerable internal deliberation at Microsoft, they decided to go back to csproj but with a much cleaner and updated format. However, this new format is only supported in VS2017.
If you want to open the projects but don't want to wait until March 7th for the official VS2017 release, you could use Visual Studio Code instead.
I ran into this issue while opening the Service Fabric GettingStartedApplication in Visual Studio 2015. The original solution was built on .NET Core in VS 2017 and I got the same error when opening in 2015.
Here are the steps I followed to resolve the issue.
Right click on (load Failed) project and edit in visual studio.
Saw the following line in the Project tag: <Project Sdk="Microsoft.NET.Sdk.Web" >
Followed the instruction shown in the error message to add xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to this tag
It should now look like:
<Project Sdk="Microsoft.NET.Sdk.Web" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
Reloading the project gave me the next error (yours may be different based on what is included in your project)
Saw that None element had an update attribute as below:
<None Update="wwwroot\**\*;Views\**\*;Areas\**\Views">
<CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
</None>
Commented that out as below.
<!--<None Update="wwwroot\**\*;Views\**\*;Areas\**\Views">
<CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
</None>-->
Onto the next error: Version in Package Reference is unrecognized
Saw that Version is there in csproj xml as below (Additional PackageReference lines removed for brevity)
Stripped the Version attribute
<PackageReference Include="Microsoft.AspNetCore.Diagnostics" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" />
I now get the following:
Bingo! The visual Studio One-way upgrade kicked in! Let VS do the magic!
The Project loaded but with reference lib errors.
Fixed the reference lib errors individually, by removing and replacing in NuGet to get the project working!
Hope this helps another code traveler :-D
#DavidG's answer is correct, but I would like to add that if you're building from the command line, the equivalent solution is to make sure that you're using the appropriate version of msbuild (in this particular case, it needs to be version 15).
Run msbuild -version to see which version you're using or where msbuild to check which location the environment takes the executable from and update (or point to the right location of) the tools if necessary.
Download the latest MSBuild tool from here.
If getting this error trying to build .Net Core 2.0 app on VSTS then ensure your build definition is using the Hosted VS2017 Agent queue.
I was getting the same messages while I was running just msbuild from powershell.
dotnet msbuild "./project.csproj" worked for me.
if the project is not a big ,
1- change the name of folder project
2- make a new project with the same project (before renaming)
3- add existing files from the old project to the new project (totally same , same folders , same names , ...)
4- open the the new project file (as xml ) and the old project
5- copy the new project file (xml content ) and paste it in the old project file
6- delete the old project
7- rename the old folder project to old name
I had the same problem and solved it by using dotnet instead of msbuild.

TFS does not build projects correctly

HI
I am trying to build my solution using TFS but it seems to skips the projects which have dependencies.
e.g Proj B depends on Proj A , then it builds only Proj A and not Proj B.
Also if i try to build the projects individually instead of the solution then it does not create the release folder. It says that the output path is not found.
Any help is much appreciated
thanks
Is the SLN file in question converted from an older version of Visual Studio?
I've found that sometimes, like when you upgrade from a VS2003 SLN file to a VS2008 SLN file, it fails in MSBuild (which is what TFS is doing essentially).
Try making a new SLN file in VS2008 (or whatever version you're using) with the same project and see if that fixes it...
If you right-click the solution, one option you'll have is dependencies. Make sure that the projects are correctly setup there, even though they may reference each other the dependencies on the solution itself may not be complete or accurate...and this is what MSBuild uses.
Have a look in the configuration manager and make sure that the build you are running has those projects selected to build.
It may be you are running the Debug configuration for your local build and then running Release on the TFS server and it's not configured the same.
