VS2010 How do I supress MSB3245 (The referenced component X does not exist)

I have some project's with various compile switches, so depending on how they are built do not need a referenced dll , so I get a warning that it does not exist.

I would like to suppress this warning so we are warning free. How do I do this 开发者_StackOverflowon the project on VS2010, what number to I put in the suppress warning box on the prject page ?

It sounds like an MSBuild warning, not a C# compiler warning (by virtue of the 'MSB') which I'm not sure is supressible. But you can just make that reference conditional, probably, something like

<Reference Condition=" $(DefineConstants.Contains('THAT_ONE_SWITCH') " ... />

though I haven't tried the exact syntax offhand.

Edit your .csproj file

Condition="Exists('..\xxx\xxx.csproj')"

<ProjectReference Condition="Exists('..\xxx\xxx.csproj')" Include="..\xxx\xxx.csproj">
  <Project>{E66B88FA-767A-46C7-BDCB-D283F6B889BA}</Project>
  <Name>xxx</Name>
  <Private>False</Private>
</ProjectReference>
