I've searched the interwebs for a solution to this to no avail. I cannot for the life of me discover how to make a .NET 6.0 project in VS 2022. The weird part is when I go to the installer, the runtime for 6.0 is selected as installed. I cannot find an SDK option in the installer's list of packages however. I have installed the SDK for 6.0 and it shows as present when I check "dotnet --info." However, whenever I go to VS to create a project the latest version of .NET listed is 4.8.
Thanks!!
the project you build is targeting . Net Framework, which latest version is 4.8. For the .Net 6 you mentioned is more likely .Net Core6.0. Please refer to the related link:.Net Framework

I've installed the preview of .NetCore 3.0 and tried to run the blazor template Blazor (ASP.NET Core hosted) in Visual Studio 2019:
The error that occured, was the following:
NETSDK1045 The current .NET SDK does not support .NET Core 3.0 as a target. Either target .NET Core 2.2 or lower, or use a .NET SDK version that supports .NET Core 3.0.
During these days I had to overcome this issue on a number of different development machines/containers: eventually, I found no less than 6 different reasons that could cause this kind of error:
Missing .NET Core 3 SDK (x86 or x64)
.NET Core SDK preview support not enabled in VS2019
VS2017 instead of VS2019
Wrong SDK path in PATH environment variable(s)
Wrong SDK path in MSBuildSDKsPath environment variable(s)
Wrong SDK version in the project's global.json file
The workarounds for those scenarios are pretty easy to understand, you basically have to either install the proper SDK or remove the "offending" SDK reference(s). However, I did my best to document them all in this post on my blog.
Following this comment, I managed to resolve the problem by installing the x86 version of the .NET Core 3.0 additionally to the x64 version. The build worked after restarting Visual Studio (2019).
for me the solution was removing a path variable MSBuildSDKsPath - Because of exploring preview sdks's i at some point declared that variable to fix another sdk bug - seems like that force sets the used version. So in my case it was set to 3.0.100 and resulted in errors when attempting to use 3.1.300
I got the same error and resolve it with checking the option "Use previews of the .NET Core SDK (requires restart)".
Open Tools > Options and try looking at "Preview Features" or ".Net Core" depending of your Visual Studio version.
Watch out of VS updates, they can disable it.
This is a very hacky-feeling solution but at least it worked. Let's say you've installed the SDK for 3.0.100-rc1-014190. It shows up in dotnet --list-sdks as expected but still doesn't seem to be detected by Visual Studio, and you get the same NETSDK1405 error when trying to build or test anything from the dotnet CLI.
Look in your dotnet SDK install directory (usually C:\Program Files\dotnet\sdk). You should see your preview SDK in there. Either create a copy or rename the existing folder to remove the preview version suffix. For example 3.0.100-rc1-014190 would instead become 3.0.100, like so:
Doing this made .Net Core 3 preview support finally work in VS2019 Preview 4 and the dotnet CLI for me.
For me it was as simple as enabling the preview in Visual Studio 2019. Unfortunately most posts that show how to do this are I believe out of date. I finally came across this stack overflow post How to enable .NET Core 3 preview SDK in VS2019? They moved the check box and it was not on by default for me.
This was a frustrating issue to track down and after doing all of the updates to VS and still not being able to install I tracked it down to an environment variable. Try removing MSBuildSDKsPath and see if that fixes your issue.
I have installed both .NET CORE 3.1. and preview 5.0. I see it when I type command:
dotnet --list-sdks
I see all packages
but when I want to use it in VS project in C# .NET CORE console app I cannot.
I have not tried .NET CORE 3.x with VS 2017 but according this page it is possible that is is supported only in VS 2019.
You might also try to restart Visual Studio. I think it loads installed frameworks only during startup.

Installing a .NetStandard 2.0 Nuget package into a VS2015 Net 4.6.1 project
(2 answers)
Closed 3 years ago.
I am so confused.. I am trying to install a nuget package that has a dependency on .NetStandard v2.0, after reading this post about it, it made sense to me that I could run any library that is dependent on .NetStandard 2.0 with .Net 4.7.2. Unfortunately, while trying to install a nuget package, it fails, saying it is not compatible with .net 4.7.2.
I am mainly trying to add the new Roslyn libraries Microsft.CodeAnalysis and if you look at the dependencies it says it supports .Net 4.7.2, the issue seems to stem from another dll its dependent on Microsoft.CodeAnalysis.CSharp.Workspaces, as that says it only has a dependency on .NetStandard 2.0. (but really .Net 4.7.2 can run .NetStandard 2.0)
Does anyone know if this is possible or will I be needing to move to .net core framework to be able to support a project like this?
Really it should say it only has a dependency on .NetStandard 2.0 but be able to get installed onto a target framework with 4.7.2 or .Net Core
Edit:
Using Visual Studio 2015 and C#6.
Its a rehosted windows workflow designer application (working on c# compilation/intellisense for inputs to the designer)
Thanks to #IanKemp for finding an answer that helped me, I will flag this post as a duplicate but I wanted to first post a step-by-step fix for future developers that may come across this.
So I downloaded the latest Nuget version (VS 2015 VSIX - latest v3.6.0) here
Then I tried to update to the latest Roslyn package via NuGet package mananger and got this error message:
The message points you to this link, that will download the .Net Standard Build Support extension: https://aka.ms/netstandard-build-support-netfx
I then tried to update to the latest Roslyn package and it all worked!!
Happy coding all.

This question is not a duplicate
I am scripting in Unity using C# with the build in MonoDeveloper-Tool.
When I run the script I got the error message, that the assemblys for framework ".netframework, version=v4.7.1" has not been found. I looked it up on stackoverflow and only found this article:
The reference assemblies for framework ".NETFramework,Version=v4.6.2" were not found
So I downloaded this version, but I can't install it, because I already have the latest version installed from .net framework, which is currently .NET Framework 4.7.2
Questions:
Is MonoDeveloper in "Unity 2018.3.12f1 Personal" not supporting this version?
Are there ways to upgrade it to make it work?
Or do I have to remove the .net-version, that I have and get an older one to make it work?
The message you are getting is ususally related to scripting backend setting in PlayerPreferences.
Here's a screenshot from 2017
and from 2019
It defaults to 3.5 for new projects, and you need to manually set it to 4.x, than pretty much all features from 4.7 work fine
Is MonoDeveloper in "Unity 2018.3.12f1 Personal" not supporting this version?
MonoDeveloper supports, but Unity doesn't.
Are there ways to upgrade it to make it work?
Try install .net 4.6 with Visual Studio Installer or upgrade the Unity.
