Your project does not reference “.NETFramework,Version=v4.6.2” framework. Add a reference to “.NETFramework,Version=v4.6.2” in the “TargetFrameworks”

Question

I can't run my unit tests.

I have the next error:

Your project does not reference ".NETFramework,Version=v4.6.2" framework. Add a reference to ".NETFramework,Version=v4.6.2" in the "TargetFrameworks" property of your project file and then re-run NuGet restore.

In app.config:

<startup>
  <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2"/>
</startup>

In Project > Properties > Application > TargetFramework (.NET Framework 4.6.2)

How can I fix it?

Answer 1

Please make the next steps

1. Clean solution
2. Clean folder "packages"
3. Delete folder "bin"
4. Delete folder "obj"

Answer 2

I up-voted Larissa but I thought it might be helpful to know how I got into this. I added a .net standard project file to my build (we target lots of platforms) and it produced the debris found in the obj folder. When the android sanity build came around, it threw up on the obj folder. My solution was to clean that folder out as a pre-build step. This is a difficult problem because it was working just fine for years...needle meet haystack.

Answer 3

I ran into the same thing with .net 4.71. In my case, I simply migrated from packages.config to "package references" per

Migrate from packages.config to PackageReference

... and it fixed my issue. For me, I was going to do this anyway, so if you're going this way already, I'd just skip the above and migrate to package references.
