MSB3270: Mismatch between the processor architecture - Fakes Framework

25
votes

Since I use Fakes Framework in my UnitTest, I get the following MSBuild warning.

warning MSB3270: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "DocumentServiceModel", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project. [C:\Projekte\XXX\XXX\XXX\Source\Testing\UT\XXX.UnitTest\obj\Debug\Fakes\ppsm\f.csproj]

The platform target of all projects in the solution is set to x86.

How can I get rid of this build warning?

UPDATE1:

I think the problem is, that the Fakes Framework creates a dynamic projekt with a platform target "Any CPU".

(C:\Projekte\XXX\XXX\XXX\Source\Testing\UT\XXX.UnitTest\obj\Debug\Fakes\ppsm\f.csproj)

This dynamic project references the assemblies from my projekt, which runs with a platform target "x86".

I have no idea, how to change the dynamic Fakes projekt to "x86".

UPDATE2:

I created a sample project and I get the same warning:

Warning 1   There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "MSBErrorTest", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

UPDATE3:

I changed my config to look like this.

  <PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Debug|x86'">
    <DebugSymbols>true</DebugSymbols>
    <OutputPath>bin\x86\Debug\</OutputPath>
    <DefineConstants>DEBUG;TRACE</DefineConstants>

    <PlatformTarget>x86</PlatformTarget>
    <ErrorReport>prompt</ErrorReport>
    <CodeAnalysisRuleSet>MinimumRecommendedRules.ruleset</CodeAnalysisRuleSet>
  </PropertyGroup>

But I still get the warning

See my updated answer below to force target platform of your project to use x86. – Eriawan Kusumawardhono
I changed this already, but the problem is still there. – Snowcrack
Hmm.... what is your project template type? – Eriawan Kusumawardhono
Visual C# - Unit Test Project - .NET 4.5 – Snowcrack
Have you updated your VS 2012 to have Update 3 installed? – Eriawan Kusumawardhono

I have got a response from Microsoft for this issue

http://connect.microsoft.com/VisualStudio/feedback/details/804933/msb3270-mismatch-between-the-processor-architecture-fakes-framework

Visual Studio 2012:

Create the following element in “Fakes\MSBErrorTestClass.fakes” file under 'Fakes' node:

<Compilation>
 <Property Name=”PlatformTarget”>x86</Property>
</Compilation>

Visual Studio 2013:

This issue has been fixed in the latest release i.e. Visual Studio 2013

Since I'm getting this error only for Fakes assemblies that I will only be running unit tests on, I decided to just ignore this error. This can be accomplished by adding this to your Fakes XML:

<Fakes xmlns="http://schemas.microsoft.com/fakes/2011/">
  <Assembly Name="FakedAssemblyName.dll"/>
  <Compilation>
    <Property Name="ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch">None</Property>
  </Compilation>
</Fakes>

Did you use 3rd party libraries? If you use them, check them to see if they use the same x86 as the target processor. It is clear that the targeted processor should be the same for all of the references, not just the target of your project.

UPDATE: Apparently this guy from Microsoft is experiencing this also. You can try to use his workaround:

http://blogs.msdn.com/b/astebner/archive/2012/05/03/10300809.aspx

From the blog entry, do this: Search for this "PlatformTarget" in your csproj file, and edit it to match this:

<PlatformTarget Condition=" '$(PlatformTarget)' == '' ">x86</PlatformTarget>

Let me know if this solve your problem.

UPDATE 2: Based on your source code of the unittest.csproj and the classlib.csproj, the configuration is still based on "AnyCPU".

Please look for this line:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">

And also this line:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">

Those target platform should also be set to use x86.

The easier way is by setting the Debug and Release by clicking "Configuration Manager..." at "Debug" combobox on Visual Studio toolbar, like in this rough illustration:

Visual Studio 2012 Debug/Release

In project_name.csproj file remove ItemGroup node where is set processorArchitecture attribute. It sth like;

<ItemGroup> <Reference ... , processorArchitecture=MSIL"> ... </ItemGroup>

That helped for me.

For anyone that landed here and has nothing to do with "Fakes", check for warnings / errors in your References. I found a ghost DLL that fortunately the project did not require, and removed it. Worked great!
