No error messages, just long delays loading forms.<br />
Further investigation shows that checking box 'Prefer 32 bit' in properties overcomes the effect.<br />
However, I am running a 64 bit system - so seems nonsensical

This worked, although seems a compromise. No-one suggested anything better.

<div class="content wysiwyg-content">
I have a very large, multi-form VB .NET program using Visual Studio 10 (VB) and .NET 4.0 with SQL Server - it works well and quickly<br />
When installed on a .NET 4.5 machine there is a 30 - 60 second pause when loading a new form into a MDI interface for BUILT applications, not apparent in debug mode on development PC.<br />
This is still present when compiled with VB13 and targeted to .NET 4.5.1<br />
The code just executes a load command, previously instantaneous. Something must have changed in the memory management with .NET 4.5<br />
How can I restore the short load times, please?

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Visual Basic.NET

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
