[c#] The OutputPath property is not set for this project

I have:

  1. Right-click on project with issue -> Unload Project
  2. Right-click on project and choose Edit *.csproj
  3. Copy-paste the configuration from existing configuration which works with specific name and targeting platform (I had Release | x64):

    <PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|x64'">
      <OutputPath>bin\x64\Release\</OutputPath>
      <DefineConstants>TRACE</DefineConstants>
      <Optimize>true</Optimize>
      <DebugType>pdbonly</DebugType>
      <PlatformTarget>x64</PlatformTarget>
      <ErrorReport>prompt</ErrorReport>
      <CodeAnalysisRuleSet>MinimumRecommendedRules.ruleset</CodeAnalysisRuleSet>
      <Prefer32Bit>true</Prefer32Bit>
    </PropertyGroup>
    
  4. Right-click project -> Reload Project
  5. Rebuild project/solution
