I have an F# project in VS 2017 using FSharp.Data.SqlProvider 1.1.11 and FSharp.Core 4.4.1.0. I have an .fsx file that does what I want. I copied its contents to an .fs file. I’m trying to call that .fs file from an MSTest class. It’s throwing an exception saying it can’t load FSharp.Core version 4.3.1.0.
To the test project I added FSharp.Core 4.3.1 and a binding redirect pointing versions 0.0.0 to 4.4.1 to 4.3.1. All is well.

I am developing a project in VS2019. When I compile it, I receive the following warning:
warning : Your project specifies TypeScriptToolsVersion 3.7, but a matching compiler was not found. The latest available TypeScript compiler will be used (3.8). To remove this warning, install the TypeScript 3.7 SDK or update the value of TypeScriptToolsVersion.
I was trying to find where TypeScript version is specified but I did not find it. Microsoft.TypeScript.targets does not define it, however, if it would, I think I could change the value by not modifying that file directly.
Where can I fix that?

Go to your project Properties -> "TypeScript build" tab and in the field: "TypeScript version" either choose specific version or select "Use latest available"
Look for TypeScriptToolsVersion tags in your csproj files and update to required version.
#BogdanRB answer above only displayed "Use latest available" and "4.2" for me. I did some research and apparently "4.2" is the SDK version installed together with Visual Studio 2019 (which I couldn't remove since it's required for lots of other VS components).
I was working on a legacy project that uses TypeScript "3.1.1", the version specified in package.json installed via npm. In order to line up the editor's IntelliSense and the compilation, and avoid using unsupported TS syntax, I've opened my ASP.NET Core MVC .csproj file and removed the following line:
<TypeScriptToolsVersion>Latest</TypeScriptToolsVersion>
Now Visual Studio's IntelliSense is compatible with the one specified in the npm package. It even works inside *.vue templates, in case you're using Vue with TypeScript.
I'm trying to use F# with VS Code (v1.17.2) on MacOS (Sierra 10.12.6)
I think i've installed latest versions of Mono and .NET SDK
I'm trying just to build the simple project described here as a test
https://github.com/s952163/FSharpVSCode
after my default installation, I could do a MSBuild and run the program in the terminal without any problem. However at that stage,
(1) Intellisense is not working properly, not recognizing Deedle
(2) in the F# explorer it would say
'TestProject1.fsproj (load failed)
when doing a right-click i got this error

to try to solve this, i typed in the following
export FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.5/
but worse, after that, the project doesn't build anymore in VS Code as I get this output when trying (Cmd-Shift-P) MSBuild: Build Project

VS Code environment is passed to msbuild when it invokes it, so setting environment variables on startup of VS Code does the trick:
FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.5/ code .
Go to project location in the terminal and then run FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.5/ code . as said before.
Then you should be able to build again.
I have an F# project that uses FSharp.Core version 4.1.0. When I upgrade to version 4.1.12, NuGet adds the following files to my project's source code directory:
any/netstandard1.6/FSharp.Core.sigdata
any/netstandard1.6/FSharp.Core.optdata
I expect NuGet to add files under the packages directory, not directly into my project. Having these files appear alongside .fs files in the project's source code tree seems odd. Is this expected behavior? Can I safely delete these files (since copies presumably exist under packages as well)?
Here's an example of what I see:
When starting a new Web Application empty MVC project in VS 2013 using .NET 4.5.2, initially, VS 2013 will be referencing Microsoft.AspNet.Mvc 5.1.2 which contains System.Web.Mvc 5.1.0. But I typically change the directory of the MVC project so I remove the project from the solution, change the directory of the project using Windows Explorer, and then add the existing project again in the solution using VS 2013.
However, upon doing this, when I look on the version of System.Web.Mvc, it is now changed to 4.0.0. I've checked the repositories.config and it has the correct path for packages.config of the project. The packages config on the project also contains version="5.1.2" although the referenced System.Web.Mvc is 4.0.0.
Furthermore, as I am trying to use IAuthenticationFilter, the interface cannot be detected by Intellisense anymore (with red squiggly line) but I can still compile and run!
Do you guys know any workaround for this? I can use NuGet to update MVC to the latest (5.2.2 I think) and the reference would be fixed but I want to use the default 5.1.2.
you can target a specific version of MVC using the Nuget Package Manager Console:
Go to
Tools > NuGet Package Manager > Package Manage Console
At the prompt you can type
update-package Microsoft.AspNet.Mvc -version 5.1.2
I believe this is the easiest way to accomplish what you are trying to achieve. You may need to remove existing references to the MVC and WebPages dlls, sometimes references stick when moving from local/GAC references to those determined by nuget.
I've had VS2013 installed on my windows 8 laptop and F# works fine.
I've since installed Xamarin Studio version 4.2.2 but unfortunately can't get any F# project to build even a very simple one.
I installed F# Version 3.0 from the Web Installer and have installed the F# addin in Xamarin Studio and restarted it. Compiling the simple Console Project just gives me the error:
Error: Build failed. See the build log for details.
With no other details anywhere.
In the fsproj file There is the following:
<Import Project="$(MSBuildExtensionsPath32)\..\Microsoft F#\v4.0\Microsoft.FSharp.Targets"
I'm not sure where the MSBuildExtensionPath32 is set or where it currently points to but if I update this to a hard-coded path that actually points at my file:
<Import Project="C:\Program Files (x86)\Microsoft SDKs\F#\3.1\Framework\v4.0\Microsoft.FSharp.Targets" />
Then when I build the project in xamarin it builds successfully.
Is there an easy way of setting the MSBuildExtensionsPath32 to my actual path for xamarin? I don't really want to resort to having to set up a .bat file to launch it but can't find an option in xamarin to configure it.
I feel I must be missing something.
Thanks
It looks like the F# project templates are using a path to an older version of F#. There is a discussion about this on the GitHub repository for the F# addin. Hopefully the project template can be updated to support different versions of F# being installed. For now you can modify your project file.
MSBuildExtensionsPath32 points to C:\Program Files (x86)\MSBuild
So you could try modifying the project template to use the following path, which should work on your machine:
<Import Project="$(MSBuildExtensionsPath32)\..\Microsoft SDKs\F#\3.1\Framework\v4.0\Microsoft.FSharp.Targets" />
