No references were found in the windows sdk (Windows 1903) - c#

I want to create simple toast notification to action center in windows 10 from a WPF app using this article.
But I got problem on Step 2:
Right click on the project => Add => Reference... => Windows => Core
What I checked:
Windows 10 SDK Installation:
Same issue with a WPF project

This error occurs after the update to Windows 1903, because Visual studio can not access C:\Windows\System32\WinMetadata


On updating to the May 2019 release of Windows 10 the directory C:\WINDOWS\SysWOW64\WinMetadata is removed and this is where Visual Studio is 2017 and 2019 is looking for all of the files.
There is 2 way to solve this:
1. Click Browse in reference manager and chose your reference from C:\WINDOWS\System32\WinMetadata.
2. Copy WinMetadata folder from C:\WINDOWS\System32\WinMetadata to C:\WINDOWS\SysWOW64\WinMetadata. and then re-open reference manager.


Looks like the parent bug is documented at https://developercommunity.visualstudio.com/content/problem/446490/visual-studio-cant-see-winmetadatadirectory-in-cwi.html
For me I clicked browse and used this path %windir%\Sysnative\WinMetadata and it worked for me. Windows 10 1903 \ VS 17


I've reproduced your issue. The node <TargetPlatformVersion> should be below the existing node <TargetFrameworkVersion> node.
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
<TargetPlatformVersion>10.0.10240.0</TargetPlatformVersion>
But there is the separate PropertyGroup with this node in your project file.


Visual Studio can not access the C:\Windows\System32\WinMetadata directory to load the windows SDK on Windows 1903.
So a downgrade from windows 1903 to 1803 solved this issue.
I have reported this problem on the visual studio developer community page.


Windows 1903:
Copy WinMetadata folder from (hidden folder) C:\WINDOWS\sysnative\WinMetadata to C:\WINDOWS\SysWOW64\WinMetadata.
Re-open reference manager.


​The folder %windir%\Sysnative\WinMetadata does not seem to exist on my Windows 1903 (OS Build 18362.900).
My workaround was to make a local copy of the required files in %windir%\System32\WinMetadata (e.g. under a lib folder in your solution) and reference them from there.
In my case, this is how I got a hold of the Windows.Data.winmd and Windows.UI.winmd files (couldn't find them on NuGet).

C# MSBuild not including the NuGet packages (works in Visual Studio 17)

I am using PackageReference in my .csproj file and my build works in Visual Studio (2017). I'm building with .net 4.5 I have looked at this:
(MSBuild not adding a /reference for nuget PackageReference when building with jenkins)
I was at first having the issue on our build server so I tried it locally on my computer. I do a restore and then the build (or rebuild). the error is:
(CoreCompile target) ->
Properties\AssemblyInfo.cs(25,12): error CS0246: The type or namespace name 'log4net' could not be found (are you missing a using directive or an assembly reference?)
And in my project I have
<ItemGroup>
<PackageReference Include="log4net">
<Version>2.0.12</Version>
</PackageReference>
Thanks in advance.
Update
I created a simple solution/project that just includes one Nuget Package. I also created it with the latest framework in case that had any bearing on the issue. Again, it builds in VS2017 but fails using MSBuild the .csproj file is

I verified that on restore the files are added to the project obj folder as well as user/roaming/nuget and user/.nuget/packages. I get the same error message as above.

Problem with library Microsoft.Office.Interop.Excel in .NET Core 2.1

I have seen this post because I have a similar error but with another library.
I have project with .NetFramework 4.6.1, and I have done another project with test that uses .net Core 2.0 in Visual Studio 2017. When i have to test a method that uses the package Microsoft.Office.InteropExcel it fails when trying to open the excel because it has not been loaded well.
The library gives a similar warning, so I suppose this is the error.

Add resource to Xamarin.Forms NuGet

I'm about to write a custom NuGet for Xamarin.Forms projects and want to include some resources (font awesome otfs) in the NuGet so the referencing projects can use them.
I've managed it to copy the files from the NuGet to the Android assets folder and mark them as assets file correctly.
However I'm not able to include them in iOS as resource files...
Did anyone know how to do that? Or how to include resources at all (with a NuGet).
Here is my code snippet from the csproj file (NuGet) that works for android but not for iOS:
<PropertyGroup Condition=" '$(Configuration)'=='Debug' ">
<DebugSymbols>true</DebugSymbols>
</PropertyGroup>
<!-- If config is release create a package -->
<PropertyGroup Condition=" '$(Configuration)'=='Release' ">
<GeneratePackageOnBuild>true</GeneratePackageOnBuild>
<GenerateDocumentationFile>true</GenerateDocumentationFile>
<!-- sourcelink: Include PDB in the built .nupkg -->
<AllowedOutputExtensionsInPackageBuildOutputFolder>$(AllowedOutputExtensionsInPackageBuildOutputFolder);.pdb</AllowedOutputExtensionsInPackageBuildOutputFolder>
</PropertyGroup>
<ItemGroup>
<Folder Include="fonts" />
<FontFiles Include="fonts\*.otf" />
</ItemGroup>
<ItemGroup>
<None Remove="#(FontFiles)" />
</ItemGroup>
<ItemGroup Condition=" $(TargetFramework.StartsWith('xamarin.ios')) ">

</ItemGroup>
<ItemGroup Condition=" $(TargetFramework.StartsWith('monoandroid')) ">
<Compile Include="android\**\*.android.cs" />
<Folder Include="Assets\" />
<AndroidAsset Include="#(FontFiles)" Link="Assets\%(Filename)%(Extension)" />
</ItemGroup>

Every C# console application prints "The system cannot find the path specified"

Every time I run a C# console application (either from Visual C# Express 2010 or Visual Studio Ultimate 2010), the first line of output is
The system cannot find the path specified
, even when my program doesn't do anything, and doesn't specify any paths. Why would this happen? Is there some way to check what the path it's looking for might be? Programs run fine otherwise. I tried to catch a System.IO.DirectoryNotFoundException but couldn't figure out where to put the try/catch blocks.
I am running Windows 7 x64, building console applications, and have tried all the different platform targets (x86, x64, AnyCPU) I can in Visual Studio, always getting the same
I have been having some other issues and have a hunch this may have something to do with those, which is why I am trying to figure it out. Thanks!
Below is z .csproj file that Visual Studio generated (this project displays the problematic behavior I am describing when run from the command line or when run from VS)

EDIT: Solved - an Autorun entry to an nonexistent directory in the registry for the Microsoft Console. See the answer below.

Can you check your registry:
\Software\Microsoft\Command Processor\AutoRun
in both the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER hives?
It may be that the command processor is trying to run something on startup that isn't there.
