After upgrading my WinForms VS2013 project to VS2015, I started seeing the MSB3884 "Could not find rule set file" warning.
A Google search turned up one MSDN article, which a Stack Overflow article points to as well as numerous other sites.

I have both VS2013 and VS2015 installed.
The project files giving the warnings (and those that do not), do not have these entries.
<CodeAnalysisRuleSetDirectories>
<CodeAnalysisRuleDirectories>
If I delete the other two entries from the project file, then the problem goes away, which is obvious, as there is no rule file set.
<CodeAnalysisIgnoreBuiltInRuleSets>
<CodeAnalysisIgnoreBuiltInRules>
I am trying to build externally using msbuild, however VS2015 tends to show the problem too.
Interestingly enough, if I click on the open button in the project properties Code Analyzer area, I do get the file.
Specifying a different rule set makes no difference. That makes me think that possibly, there is an environment variable setting, not that any come to mind. Code Analyzers is a function of the project file. I can add a directory attribute, but the consensus is to take out paths, the <CodeAnalysisRule*Directories>
.
The GUI uses defaults:
'
Here is a typical project file fragment.
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Debug|x86'">
<DebugSymbols>true</DebugSymbols>
<OutputPath>bin\x86\Debug\</OutputPath>
<DefineConstants>TRACE;DEBUG</DefineConstants>
<DebugType>full</DebugType>
<PlatformTarget>x86</PlatformTarget>
<CodeAnalysisIgnoreBuiltInRuleSets>true</CodeAnalysisIgnoreBuiltInRuleSets>
<CodeAnalysisIgnoreBuiltInRules>false</CodeAnalysisIgnoreBuiltInRules>
<Prefer32Bit>false</Prefer32Bit>
<TreatWarningsAsErrors>true</TreatWarningsAsErrors>
<CodeAnalysisRuleSet>BasicCorrectnessRules.ruleset</CodeAnalysisRuleSet>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Debug|x64'">
<DebugSymbols>true</DebugSymbols>
<OutputPath>bin\x64\Debug\</OutputPath>
<DefineConstants>TRACE;DEBUG</DefineConstants>
<DebugType>full</DebugType>
<PlatformTarget>x64</PlatformTarget>
<CodeAnalysisRuleSet>MinimumRecommendedRules.ruleset</CodeAnalysisRuleSet>
<CodeAnalysisIgnoreBuiltInRules>false</CodeAnalysisIgnoreBuiltInRules>
</PropertyGroup>
Without getting rid of the Code Analysis lines from the project file, though saving a project file again would just add it back, how can I eliminate/fix the warning?
I've just had the same problem after upgrading from VS2013 to VS2015.
My solution was:
I hit this warning after migrating from VS 2013 to VS 2015 as well. In my case the error was Could not find rule set file "AllRules.ruleset"
. The fix for me was to change the VisualStudioVersion
setting in the .csproj file to be 14.0
so that it looks in the correct rule set folder:
After that and a rebuild, the warning was resolved. Much easier.
