It was not possible to find any compatible framework version. The specified framework 'Microsoft.NETCore.App', version '2.2.0' was not found

问题

I had a .Net Core console app built and deployed.

The project's Platform target is x86.

Target framework is .Net Core 2.2(x86).

Although .Net Core 2.2 (x86) SDK is installed, I get following error after executing the command dotnet myapp.dll in Developer Command Prompt VS2017.

It was not possible to find any compatible framework version
The specified framework 'Microsoft.NETCore.App', version '2.2.0' was not found.
- The following versions are installed:
2.0.7 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
2.0.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
2.1.5 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

The .Net Core 2.2(x86) SDK was installed under path "C:\Program Files (x86)\dotnet\shared", and System Environment Variables contains "C:\Program Files (x86)\dotnet\".

Any suggestion? Thanks!

~~~Update1

Following are part of .csproj info, sorry can't show whole thing.

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <Platforms>AnyCPU;x86;x64</Platforms>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <PlatformTarget>x86</PlatformTarget>
    <Prefer32Bit>true</Prefer32Bit>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|x64'">
    <PlatformTarget>x64</PlatformTarget>
    <Prefer32Bit>true</Prefer32Bit>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|x86'">
    <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>

Some months ago a Visual Studio update broke my capability of running tests. One of the issues was exactly this error. I have the x64 version of the SDK installed but VS tests runner was attempting to use the x86 version. The fix is just changing a setting inside the Test Explorer: Processor Architecture for AnyCPU Projects -> x64.

It seem to be a known issue for .Net Core installation, github.com/dotnet/core-setup/issues/4350

I have to uninstall all .Net Core packages, both x64 and x86, then reinstalled .Net Core x86 package. And that solved the problem.

Can you change .csproj to add RunCommand like below:

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

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

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
    <Prefer32Bit>false</Prefer32Bit>
    <PlatformTarget>x86</PlatformTarget>
    <Optimize>false</Optimize>
    <RunCommand Condition="'$(PlatformTarget)' == 'x86'">$(MSBuildProgramFiles32)\dotnet\dotnet</RunCommand>
    <RunCommand Condition="'$(PlatformTarget)' == 'x64'">$(ProgramW6432)\dotnet\dotnet</RunCommand>
  </PropertyGroup>

</Project>

Maybe you need to add 2 line of RunCommand and update the correct path of dotnet on your laptop.

This issue happens when you are on windows 64bit and run x86 application.

you only needed to install your .net core SDK version in your computer or your server. this link has all version of .NET Core SDK. download and install it and run and test your app again.
