@Pasc059 If you use the new .csproj format (and most probably you do so) just add these lines into the project file:
<PropertyGroup>
<AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
<AppendRuntimeIdentifierToOutputPath>false</AppendRuntimeIdentifierToOutputPath>
</PropertyGroup>
See more details here (in the Note section).
