Error occurred in deployment step 'Install app for SharePoint': Sideloading of apps is not enabled on this site

If you are starting to develop Apps for SharePoint or Project Server and you encounter the problem where you get the following error message:

 Error     1     Error occurred in deployment step 'Install app for SharePoint': Sideloading of apps is not enabled on this site.             0     0     SharePointApp_01  


It is usually because the site you are developing against is not a SharePoint development site. The easiest way to solve the problem is of cause to create a new SharePoint Development site.



However this is not always possible and you might have a lot of content on your site you want to test against. Furthermore if you are creating a Project Server App I have not found a way to create a Project Server Development site.

Convert SharePoint (and Project Server) site into a Development site
This can simply be done through Powershell. To be able to run Powershell agains online you will need to download SharePoint Online Management Shell.

The Powershell script you need to run is:

 $programFiles = [environment]::getfolderpath("programfiles")  
 add-type -Path $programFiles'\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll'  
 $siteurl = 'https://MyTenant.sharepoint.com/sites/pwa'  
 $user = 'admin@MyTenant.onmimcrosoft.com'  
 $pass = ConvertTo-SecureString -String 'password123' -AsPlainText -Force  
 [Microsoft.SharePoint.Client.ClientContext]$cc = New-Object Microsoft.SharePoint.Client.ClientContext($siteurl)  
 [Microsoft.SharePoint.Client.SharePointOnlineCredentials]$spocreds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($user, $pass)  
 $cc.Credentials = $spocreds  
 $site = $cc.Site;  
 $featureDevSiteUid = new-object System.Guid "AE3A1339-61F5-4f8f-81A7-ABD2DA956A7D"  
 $site.Features.Add($featureDevSiteUid, $true, [Microsoft.SharePoint.Client.FeatureDefinitionScope]::None);  
 $cc.ExecuteQuery();

Sharepoint 2013 - Fullscreen mode/hide quick launch

If you want to hide the quick launch on a SharePoint page or web part page in 2013 you could of cause use CSS scripts as in 2010.
But as a new thing in 2013 the user have the possibility to click on full screen mode. so why not load your page in this mode and then the user can choose to exit the mode if he prefers.

Add a content editor webpart to your page and click on Edit HTML from the ribbon.
Add the following code:

<script type="text/javascript">
window.onload = function()
{
  SetFullScreenMode(true);
}
</script>

Install DLL in GAC - Windows 2008/2012 (Using Powershell, No GacUtil.exe)

If you want to install a DLL in the GAC and do not have the GACUtil.exe available. Powershell is properly the easiest way to procede.

Before Powershell you would properly just drag the DLL file into the C:\Windows\Assembly but this option is usually not available anymore.

Powershell - Add DLL to GAC So to install a DLL file in the GAC simply execute the below Powershell script. Remember you migth want to run the Powershell prompt as an administrator.
[System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")$publish=New-ObjectSystem.EnterpriseServices.Internal.Publish$publish.GacInstall("c:\temp\MyDllFile.dll")iisreset
The first line adds a reference to the assembly we need to be able to mange the GAC.
The second and third lines retrives the GAC object and publish a new DLL file to it.
The last line resets the Internet Information Services. This is only needed if your DLL file is used in a websi…

Reporting on Microsoft Planner or Microsoft Staffhub!

Reporting on Planner or StaffHub!


For a long time I have been waiting for the reporting API for Planner and Staffhub. Today I got tired of waiting and found another way to do it.

I manage to create a PowerBI report based on all the planner plans I have access to and the same method will work for Staffhub and properly many other services such as Microsoft Tasks, Microsoft Forms, etc. 


How?Easy, but requires some Azure, Flow and PowerBI knowledge. These are the steps to I used: 1.Create an Azure Blob to hold the data 2.Create a Flow to save Planner data in the Blob 3.Access the Blob from PowerBI Azure – Blob!So first, lets create a Blob. No, not that kind of Blob. Access the Azure portal - https://portal.azure.com/ Select New and search for “storage account” Fill out the form and click create. I kept all settings to their default Access the new storage and locate/copy the Storage Account Name and Access Key – you will need this for connections to Flow and PowerBI. Next let’s create a Blob Container an…
