c# - InvalidProgramException with shims in Visual Studio 2015 -

an similar question has been asked while ago not answered yet. , since setup little different, start new try:

i demonstrate shortened version of code, short version produces error.

i have method returns instance of system.printing.localprintserver:

public class printserverprovider {     public localprintserver provide()     {         return new localprintserver(new string[0], printsystemdesiredaccess.enumerateserver);     } } 

for method implemented unit test using shims:

[testclass] public class printserverprovidertests {     [testmethod]     public void provide_success()     {         using (shimscontext.create())         {             bool constructorcalled = false;             shimlocalprintserver.constructorstringarrayprintsystemdesiredaccess = (instance, props, access) =>             {                 constructorcalled = true;             };              printserverprovider provider = new printserverprovider();             localprintserver server = provider.provide();             assert.isnotnull(server);             assert.istrue(constructorcalled);         }     } } 

in visual studio 2013 test works fine.
in visual studio 2015 (update 1), when tested method calls new localprintserver(...) an

invalidprogramexception @ system.printing.localprintserver..ctor(string[] propertiesfilter, printsystemdesiredaccess desiredaccess) @ demoproject.printserverprovider.provide() in c:\projects\demoproject\program.cs:line 10. ...

is raised. (the normal productive call works fine. exception raised when running test method)

the referenced assemblies are:

• system.printing (v4.0.30319) c:\program files (x86)\reference assemblies\microsoft\framework.netframework\v4.5\system.printing.dll
• system.printing.4.0.0.0.fakes
• microsoft.qualitytools.testing.fakes (v2.0.50727) c:\program files (x86)\microsoft visual studio 14.0\common7\ide\publicassemblies\microsoft.qualitytools.testing.fakes.dll

system.printing.fakes

<fakes xmlns="http://schemas.microsoft.com/fakes/2011/"> <assembly name="system.printing" version="4.0.0.0"/>   <stubgeneration>     <clear/>   </stubgeneration>   <shimgeneration>     <clear/>     <add fullname="system.printing.localprintserver!"/>   </shimgeneration> </fakes> 

both projects (productive , test) use .net framework 4.5.

i tried resetting framework references. tried different versions of referenced assemblies. , tried 64bit , 32bit in variations.

in real code, use shims of other classes too. localprintserver class exception occurs.

can explain causes invalidprogramexception , how solve it?

i set bounty on this question, solved same answer. feel free post there if think answer bounty-worth.
