Attempting to upload the digitally signed version of thi sextension produced thewell-documented 'Path may be too long in VSIX' error.

If you feel that you've benefited significantly from any of these business types, pleaseconsider making a donation to help cover the cost of developing them. I'd prefer to let people decide the extension is worth something to them (saving time, impressing bosses/clients, etc.), rather than just setting a fixed price.

Donations will help to ensure that extensions can continue to be created for the benefit of the LightSwitch community.
