cannot find \Version\AssemblyVersionInfo.cs

I got this error when trying to build a solution in Visual Studio 2015 that I pulled out of source control recently. To fix it, I closed Visual Studio and opened a lot of the .csproj files for the projects in Notepad to see something like this amid the XML inside each one:

<ItemGroup>
   <Compile Include="..\Version\AssemblyVersionInfo.cs">
      <Link>AssemblyVersionInfo.cs</Link>
      <SubType>Code</SubType>
   </Compile>
   <Compile Include="AssemblyInfo.cs">
      <SubType>Code</SubType>
   </Compile>
   <Compile Include="Milliman.cs">
      <SubType>Code</SubType>
   </Compile>
</ItemGroup>

 
 

Getting rid of the first "Compile Include" and resaving the files fixed the error. What is above thus becomes:

<ItemGroup>
   <Compile Include="AssemblyInfo.cs">
      <SubType>Code</SubType>
   </Compile>
   <Compile Include="Milliman.cs">
      <SubType>Code</SubType>
   </Compile>
</ItemGroup>
