• 752266: Visual C++ application that is compiled by using the cl /O2 /arch:AVX /EHsc command in the Visual Studio 2012 x86 Native Tools Command Prompt intermittently exits.

• Assume that you configure the platform target to x64 for a Visual C++ application. You compile the application by using the /O2 or /Ox optimization option. In this situation, incorrect code is generated when the compiler converts int64 type to int32 type inside a loop. For example, you may compile the following code:
  

  int A[8];for (__int64 i=0; i<8; i++) { A[i] = i + 1;}

• When you compile a Microsoft Visual C++ application that contains the following code together with the /analyze option on an ARM platform, an internal compiler error occurs:
  

  class Base {};
  
  template <typename T>
  class Derived : public Base {};
  
  template <typename P3>
  Derived<P3> Make( P3 p3 );
  
  void foo()
  {
  Base& b = Make(sizeof(long));
  }
  

• IntelliSense becomes unresponsive when you type some code into the editor, specifically when you add overload functions to partial classes. For example, you use code that resembles the following:
  

  Namespace N { partial ref struct S { }; ref struct S { void test(); void test(int); void test(int, int); }; }

• IntelliSense does not work in a source file that contains lambda expressions that have more than one return value. For example:
  

  [] () { bool b; std::wstring k; if(b) return k; else return k; };

• When you use Intel's new TSX (Transactional Synchronization Extensions) through intrinsics provided by Visual Studio 2012 on Intel's Haswell hardware, the C++ compiler generates incorrect code. This causes the transaction operation to be non-exclusive.

• C++ compiler generates incorrect function hints in the fixup record in PDB files.

• When you create an empty Visual C++ project, the SDL checks option is cleared even though the SDL checks check box is selected in the Application wizard.

• X64-based Visual C++ tool set does not contain all cumulative fixes for the x86-based Visual C++ tool set in Visual Studio 2012 updates.

• Fixed a compiler crash when certain nested loop code is compiled.

• An internal compiler error occurs when you buiuld an LLVM-based project by using an x64-based compiler.

• Incorrect machine code is generated for a Visual C++ application. A loop may be skipped unconditionally.

• Application intermittently crashes on Windows Phone when you create an asynchronous operation with Parallel Patterns Library (PPL).

• An internal compiler error may occur when you use x64 native C++ compiler to compile a C source code that contains the following pattern of code inside a loop:

  A = (B < C ? B : C);

• When you installed a RTM version of language package on Visual Studio 2012 that has Visual Studio 2012 updates installed. After you configure the Visual Studio 2012 to use the newly-installed language, you experience the following symptoms:

  • You cannot create new Win32 or MFC application in wizard.

  • You cannot upgrade projects from earlier versions.

  • Displayed language is not the user-configured language.

• Assume that you have a MFC project and you are using Messages tab in Class Wizard to implement a message handler for WM_CREATE message. After you click Add Handler, you cannot build the project because the code that is generated is incorrect.

• When you build binaries for x64 or ARM platforms in debug mode and with incremental linking option enabled, the pdata corrupts sometimes. This causes the following issues:

  • Exception handling code does not work.

  • Windows API RtlLookupFunctionEntry() does not work.

• Assume that you have a C++ Windows Store project or a C++ Windows Store Unit Test project that references a Windows Store exe project, there is no IntelliSense showed for the Windows Store exe project in your project.

• Illegal instruction is generated as "mov eax,bh".

• Assume that you have a Windows Phone or a Windows Store project that references a separate project that contains assets that are created by using Visual Studio Graphics tools. When you try to build the main project, the assets are not deployed together with the main project. This causes build errors in the Windows Store application or run time errors in the Windows Phone application.

• Several stability and performance improvements for Graphics Diagnostics.

• When you try to install a Visual Studio 2012 Update 1 package that does not contain Entity Framework tools, you receive the following error message:

  Entity Framework Designer for Visual Studio 2012 - enu package failed

• When you install Visual Studio 2012 updates, Entity Framework tools will be installed in English regardless of the locale of Visual Studio 2012 that you have installed.

Microsoft Test Manager

• Assume that you run a test that has no expected results, and you file a bug during the test. In this situation, the test is auto-computed to pass.

• A shared test step may be deleted unexpectedly when you delete a selected test step.

• The following error occurs when you try to create a new environment in MTM Lab Center:

  Error in querying the running virtual machines.
  Specified argument was out of the range of valid values.

Unit testing

• Test methods with TestInitialize attributes may be called in an incorrect sequence.

Load Testing

• Unable to run an x86-targeted test DLL from MTM against a Test Controller that is running on an x64 operating system.

Test and Lab Manager

• Assume that you have applied Visual Studio 2012 Update 1 on a computer that has TFS 2012 and Visual Studio 2012 installed. You try to run a build that contains tests on the computer. In this situation, the build fails together with a MethodNotFoundException exception.

• Merged code coverage files display incorrect coverage data.

• 773691: Visual Studio 2012 uses the root namespace instead of the assembly name to generate the Uri for an XAML page and causes an XamlParseException exception at run time.

• 758739: IntelliSense does not recognizes x:Type and x:Static in a .NET Framework 3.5-based WPF application.

• Visual Studio 2012 does not show custom shortcut menu for third-party WPF control.

• When you interact with the designer in a Setup and Deployment project type, a NotImplementedException exception appears on the designer.

• XAML editor may stop automatic outlining and IntelliSense may not work after installing Visual Studio 2012 Update 1.

• Portable Class Library code running in Blend designer fails to load Microsoft.CSharp.dll file.

• Portable Class Library throws an exception in the XAML designer when it is not configured to target Silverlight 4 and higher.

• C++ compiler fixes in Visual Studio 2012 Update 1 are not applied to windows phone developer tools.

• Visual F# Portable Library Project issues

  • Queries that work as usual in F# Interactive and on the desktop framework will fail at run time with System.NotSupportedException when they are used in an F# portable library for a Silverlight or Windows Store app.
