如何从 Visual Studio 2013 中禁用 mscorlib.dll？

Question

I am trying to use a custom standard library in visual studio 2013 and can't seem to figure it out. I have no problems compiling on the command line using /nostdlib although I would like to be able to take advantage of intellisense in the IDE. I have removed all references except for my custom corelib and I am getting conflicting code errors due to having two variations of mscorlib.

The VS documentation says:

To set this compiler option in the Visual Studio development environment

1. Open the Properties page for the project.

2. Click the Build properties page.

3. Click the Advanced button.

4. Modify the Do not reference mscorlib.dll property.

Although this does not seem to be the case, as this option does not exist. Does anyone know how I can disable mscorlib.dll in vs2013?

Answer 1

This is an old question, but, indeed - while the UI option has disappeared (or moved) and the documentation remains misleading to this day, you can still replicate the effect by adding <NoStdLib>True</NoStdLib> into your .csproj near the other options found in advanced settings:

<Project ToolsVersion="12.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    ...
    <TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
    <FileAlignment>512</FileAlignment>
    <NoStdLib>True</NoStdLib>
    <TargetFrameworkProfile />
  </PropertyGroup>
...
</Project>

To workaround the same problem in Visual Studio 2017 , adding the following Property Group declarations inside the .csproj file (you can unload project from Visual Studio and Right Click and choose Edit) did the trick to suppress the compiler errors:

<PropertyGroup>
  <NoStdLib>true</NoStdLib>    
  <DisableHandlePackageFileConflicts>true</DisableHandlePackageFileConflicts>
</PropertyGroup>
...
<ItemGroup>
  <Reference Include="mscorlib">
  <HintPath>..\path to custom mscorlib.dll</HintPath>
</Reference>
