CAS Policy changes in .NET 4.0 Visual Studio Beta 2

I ran into a interesting exception yesterday when trying to run NServiceBus on Windows 7 with Visual Studio 2010 Beta 2

System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=131738 for more information.

I found some more info on this blog.

Basically the fix is to add the following to your App.Config

 <runtime>
    <loadFromRemoteSources enabled="true"/>
  </runtime>

Freeing Disk Space on C:\ Windows Server 2008

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.

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

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 graduated rate, b…

Populating Duplicate Fields with DocuSign's REST API

If you're using DocuSign's REST API for integrating e-Signing into your application then it's possible you'll come up against the issue of duplicate fields not populating. This is when you have the same field with the same label e.g. Company Name in multiple places on the Document but you only want to send a single label, value instance to the API and have it populate in all places where the field is.

When you pass the label and value like so:

{ label: "company_name", value: "Blogger.com" }
If you have the field company_name more than once in the document then only the first field will be populated.

After a lot of digging into the DocuSign documentation I discovered the solution is to append "\\*" to the label name:

{ label: "\\*company_name", value: "Blogger.com" }
Why this isn't the default behaviour is beyond me but the solution works as expected.
