Visual Studio 2010 Beta 2 – Upgrade Issues

Image
By

Just upgrading some of my projects and am going to note some of the breaking changes for anyone else.

Entity Framework 

System.Data.Objects.ObjectContextOptions

//deprecated
ContextOptions.DeferredLoadingEnabled = true;

//beta 2
ContextOptions.LazyLoadingEnabled = false;


Update:

It seems the T4 template for the Self Tracking Entities was not updated with this change for the ContextOptions.

Here is the Fix

Just unzip and replace the following files.

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCache\CSharp\Code\1033\AdoNetEntityDataModelT4SelfTrackingCodeGenCsharp.zip\EF.SelfTracking.Context.ctp.CS.tt

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCache\CSharp\Code\1033\AdoNetEntityDataModelT4PocoCodeGenCSharp.zip\EF.Poco.Context.ctp.CS.tt

Workflow

When I opened up my Solution with a Workflow project it was unable to open it.
It seems they have now added two new Workflow Project Types.

WCF Workflow Service Application
Workflow Console Application

Also it seems the XAML has changed and the designer can’t interpret old Activities.

Update:

Found another bug which I just battled an hour with.

My Custom Activities weren’t showing up in the Workflow toolbox it turns out that they only show up when the Activity Library project is not contained in a Solution folder.


The referenced assembly "DLLName.dll" could not be resolved because it has a dependency on "System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client".

ASP.NET MVC Release Candidate - Upgrade issues - Spec#

By
First of all, great news that the ASP.NET MVC Release Candidate has finally been released.  Full credit to the team for the hard work on this.  You can get the download here  However this is the first time I have had upgrade issues.  Phil Haack has noted some of the issues here   If like me you have lot's of CTP's and Add-Ins then you might experience some pain in Uninstalling MVC Beta on Vista SP1  This is the list of Add-Ins / CTP's I had to uninstall to get it to work  Spec# PEX Resharper 4.1  Sourcelinks ANTS Profiler 4   Can't say I'm too impressed as it wasted over an hour of my time.  As it turned out Spec# turned out to be the offending culprit, it's forgiveable to have issues with a third party product but a Microsoft one? Guess no-one on the ASP.NET team has Spec# installed.

Freeing Disk Space on C:\ Windows Server 2008

By Will Beattie
  I just spent the last little while trying to clear space on our servers in order to install .NET 4.5 . Decided to post so my future self can find the information when I next have to do this. I performed all the usual tasks: Deleting any files/folders from C:\windows\temp and C:\Users\%UserName%\AppData\Local\Temp Delete all EventViewer logs Save to another Disk if you want to keep them Remove any unused programs, e.g. Firefox Remove anything in C:\inetpub\logs Remove any file/folders C:\Windows\System32\LogFiles Remove any file/folders from C:\Users\%UserName%\Downloads Remove any file/folders able to be removed from C:\Users\%UserName%\Desktop Remove any file/folders able to be removed from C:\Users\%UserName%\My Documents Stop Windows Update service and remove all files/folders from C:\Windows\SoftwareDistribution Deleting an Event Logs Run COMPCLN.exe Move the Virtual Memory file to another disk However this wasn’t enough & I found the most space...

CPF Contribution Rates for new Singapore Permanent Residents (SPR’s)

By Will Beattie
Recently my wife and I applied and got approved for Singapore Permanent Residency. After completing the formalities the most significant immediate change is the contribution to CPF which is Singapore’s mandatory social security savings scheme requiring contributions from employers and employees. CPF contributions start from the date you obtain SPR status, which is the date of the entry permit.   Being a relentless budgeter I needed to know exactly how much I and my employer would have to contribute so that I could adjust my budget accordingly as the employee contributions get deducted from the monthly salary. After doing some research I discovered that there is a “graduated” approach to CPF contributions for new SPR’s where the contributions gradually increase in the first and second year and then upon reaching the third year are at the full amount. Note: There is an option for employers to contribute the full amount for year 1 and year 2 and the employee can use the gra...
