Reopened Issue: LinqToSqlPrimaryKeyTemplate generates clustered primary key for UNIQUEIDENTIFIER columns. [13876]

Clustered UNIQUEIDENTIFIER columns result in severe performance problems due to excessive page splitting. Should it generate a non-clustered key only for UNIQUEIDENTIFIER columns? Or, should it be an option?

Reopened Issue: Error in DteProcessor.FindProjectItemCollection - incorrect ProjectItems instance returned for files in subfolders [17240]

OlegSych — Fri, 14 Jun 2013 07:30:13 GMT

When generating an output file with setting Template.Output.File to some subdirectory, the DteProcessor.FindProjectItemCollection returns a ProjectItems instance pointing to the root directory of the project, not to the target subfolder. Then UpdateOutputFiles methods acts like the target file has been moved within the project structure. ( "if (outputItem.Collection != collection)" condition is then valid)
I solved this issue by commenting out the condition in the FindProjectItemCollection method, that checks, whether the project is a database project. Then the loop on the end of the method is executed for any project kind and the correct ProjectItems collection is returned.

Commented Issue: Multi-file speed suggestion [18919]

For whatever reason, generating a file from a template is a very slow process. I don't know if this is normal or not, but it seems like it is. Here's what I'm assuming about T4 Toolbox and how I suggest to improve the speed:

I'm assuming that the way T4 Toolbox is effectively re-adding the file to the project each time it is generated. I think Visual Studio then does whatever it does when a file is added. If this is normally not a slow process then perhaps the slowness is caused by Resharper re-parsing the file or by Visual Studio parsing the XAML or perhaps by one of my add ins.

At any rate, I noticed that the Entity Framework template library that is available in Visual Studio 2010 *isn't slow* in the case when the file already exists (i.e. after it builds the first time). I looked through this library, and discovered that the reason for this is because it actually compares the contents that it is about to write to a file with the contents that are already there. If they are the same then it leaves the original file alone.

Apparently the process of generating the file into memory, reading the original file into memory, and then comparing the two strings is faster than adding a file to a project in Visual Studio (at least for me). In fact, I'd say at least 10x faster.

Could you change T4 Toolbox to work like this, as well? Waiting for all of my files to generate is becoming very time consuming.

Closed Issue: Syntax Highlighting interferes with Tangible T4 [24094]

OlegSych — Fri, 22 Mar 2013 01:50:57 GMT

When running the T4Toolbox Extension the syntax highlighting options interfere with Tangible's highlighting (Turning off the highlighting in options doesn't restore the Tangible Highlighting).

Is there a way to configure the add-in to not perform highlighting for T4 and not interfere with any existing syntax highlighters?
Comments: T4 Toolbox stops syntax highlighting as soon as you click "OK" in the options dialog. I would expect Tangible to take over at that point, or at least after you close and reopen the file. Having to disable and re-enable the extension is a non-ideal workaround. I will take a closer look if this affects a lot of people.

That's weird, disabling and re-enabling the T4 Toolbox extension seems to have restored the Tangible functionality.

Closed Issue: Can't invoke T4 tt's from VS2012 Addin using latest beta [23880]

OlegSych — Wed, 06 Feb 2013 01:56:35 GMT

In VS2010 I was able to invoke my T4 tt's from within a Visual Studio Addin using the following technique:
TextReader tr = new StreamReader(ttFile);
string content = tr.ReadToEnd();
IServiceProvider serviceProvider = new ServiceProvider((Microsoft.VisualStudio.OLE.Interop.IServiceProvider)m_applicationObject.DTE);
ITextTemplating tt = serviceProvider.GetService(typeof(STextTemplating)) as ITextTemplating;
tt.ProcessTemplate(ttFile, content, (this as ITextTemplatingCallback), null);

I've moved to VS2012 and upgraded to the T4 3.0.8 beta, but calling ProcessTemplate now throws the Exception below. Any ideas? Thanks

Closed Issue: T4 with VS2012 fails when debugging a template [23807]

OlegSych — Wed, 23 Jan 2013 02:20:10 GMT

With VS2012 when I try to debug a T4 template using the Debug T4 Template command from Solution Explorer then the toolbox throws a NullReferenceException when it tries to eval DefaultNamespace. Up to that point I can step through my template logic. I tried this by creating a brand new script (the one that get installed with the toolbox). If I just run the T4 tool directly (without debugging) then it works. The debugging approach discussed on the site about starting a second VS instance is outdated and seems like overkill since VS supports it directly now.
Comments: Unfortunately, this is a problem in the implementation of "Debug T4 Template" in Visual Studio 2012. I have submitted it at https://connect.microsoft.com/VisualStudio/feedback/details/777202/itexttemplatingcomponents-hierarchy-is-null-when-debugging-a-t4-template. Please vote on it to improve its chances of being fixed.

Closed Issue: Skip DteProcessor.UpdateFiles when generating outside current project [22469]

OlegSych — Sat, 29 Dec 2012 06:27:56 GMT

I created a project just to host a bunch of T4Toolbox templates, but instead of generating files inside the project, I wanted to generate a complete solution outside current one. The problem with this is that everytime a T4Toolbox templates is disposed, it tries to include the generated file on current project. 
 
The OutputInfo class could include a property to indicate that its output should not be included in current project.

Set Output.PreserveExistingFile=true

i have a question. it's said that t4 toolbox is not compatible to .net framework 4.5 yet, and based on this claim the developer in my company doesn't want to upgrade the project to .net 4.5. i want to know that if it's true or not and if yes what we should do to solve the problem.
