If you would prefer to use your own custom colors for the theme, you can do this with the CustomColorTheme resource dictionary (also included in the materialDesign xlmns). A final App.xaml should look something like this:

There are several resources available. There is a wiki, gitter chat room, and as always, Stack Overflow (with tag material-design-in-xaml). Additionally, I maintain a repository with lots of small example projects. Let me know what examples you would like to see.
You are correct. The default (implicit) style for all of the controls get pulled in from the reference in App.xaml to the MaterialDesignTheme.Defaults.xaml resource dictionary. It now contains references to most of the control resource dictionaries, so you likely can omit the specific includes to each of the control specific resource dictionaries. You can see the complete list of which resource dictionaries are merged in here:
If it helps you visualize it better, you can think of a reference as a linking pointing to a web page, or a shortcut pointing to a file on your computer. Types such as int (and the other numerical primitive types), DateTime, and boolean are value types. That is, structs are value types. Classes are reference types.
Null reference errors are responsible for a good percentage of all application bugs. They are usually very simple problems caused by not adding additional logic to ensure that objects have valid values before using them. Here are some ways to avoid NullReferenceException.
The good news is that a lot of null reference errors can be avoided by adding additional logic and code to ensure objects are not null before trying to use them. Developers should always assume that everything is invalid and be very defensive in their code. Pretend every database call is going to fail, every field is going to have messed up data in it. Good exception handling best practices are critical.
Null reference exceptions are a very common problem in .NET and most programming languages. Luckily, we can all blame Tony Hoare. He invented null references and even calls it the billion-dollar mistake.
Prefix is a very lightweight code profiler that can help even the most experienced developers in discovering slow SQL queries and even hidden exceptions. With Prefix, developers can validate the performance of their code as it is written. As a result, they push better code to test and receive fewer support tickets.
With this new and improved Prefix, developers receive more OS support, more programming languages, modern .NET profiling, dedicated log viewer, and Prefix is now a native application for Windows and macOS.

You will need to place the sequence 1 in InitAllSettings xaml, sequence 2 in InitAllApplications and sequence 3 in Process xaml and pass the arguments accordingly. And place all your flows in Try Catch.

DATE: This final rule is effective March 20, 2017. [Note: The Board changed the effective date to March 21, 2017, as indicated in a notice published on March 2, 2017.] However, compliance with the section 508-based standards is not required until January 18, 2018. Compliance with the section 255-based guidelines is not required until the guidelines are adopted by the Federal Communications Commission. The incorporation by reference of certain publications listed in the final rule is approved by the Director of the Federal Register as of March 20, 2017.
From the outset, one of the Access Board's primary goals in this rulemaking has been to increase harmonization with international standards relating to ICT accessibility that have been developed worldwide over the past decade. Some of these standards (such as WCAG 2.0) are incorporated by reference in the Revised 508 Standards and 255 Guidelines. For other standards (such as EN 301 549, which is the European accessibility standard for public ICT procurement), harmonization comes in the form of ensuring that the relevant accessibility specifications in such standard and the final rule can both be met simultaneously without conflict. Harmonization with international standards and guidelines creates a larger marketplace for accessibility solutions, thereby attracting more offerings and increasing the likelihood of commercial availability of accessible ICT options.
In general, commenters continued to agree with our approach to address ICT accessibility by focusing on features, rather than discrete product types. Commenters supported the conciseness of the proposed provisions in the 2011 ANPRM, and asked for further streamlining where possible. Commenters also generally voiced strong support for the Board's decision to incorporate by reference WCAG 2.0 and apply it to all types of covered ICT; several commenters did, however, question the propriety of applying WCAG 2.0 to non-Web ICT.
In general, commenters spoke positively about the proposed rule, and noted that it was much improved from earlier iterations in the 2010 and 2011 ANPRMs. By a wide margin, the single most commented-upon aspect of the proposed rule (and the issue on which commenters expressed the greatest unanimity) was timing. Characterizing refresh of the 508 Standards and 255 Guidelines as "long overdue," these commenters urged the Access Board to issue its final rule as expeditiously as possible. On substantive matters, a large number of commenters addressed some aspect of the requirements for electronic content, with the bulk of these comments relating to Section 508-covered content. Another technical area receiving sizeable comment was our proposal that, under both Sections 508 and 255, WCAG 2.0 and PDF/UA-1 serve as the referenced technical standards for accessibility of electronic content, hardware, software, and support documentation and services. Additionally, real-time text (RTT) was a subject of great interest to NPRM commenters, with most commenters representing disability advocacy organizations and academicians supporting the Board's RTT proposal, while ITC manufacturers and trade groups expressed opposition. Further, the issue of harmonization with EN 301 549 received considerable comment. In general, ITC industry-related commenters urged the Board to harmonize more closely with this European specification. Disability advocacy organizations and consumer-related commenters, on the other hand, viewed the proposed rule and EN 301 549 as well harmonized already and expressed concern that further harmonization would be improvident because, in their view, EN 301 549 set forth weaker accessibility requirements in some areas.
Relying on the working group's findings, in the NPRM the Board proposed to directly apply WCAG 2.0 to all non-Web documents and software. NPRM, 80 FR at 10895. Sixteen commenters responded to the proposal of applying WCAG 2.0 to non-Web content. Six commenters (five ICT companies and trade associations, and an ICT subject matter expert) strongly advocated for returning to the previous approach of reprinting three variants of WCAG 2.0 in the 508 Standards and rewriting the requirements with non-Web specific terminology. These commenters asserted that agencies would not be able to consistently apply the WCAG 2.0 success criteria to non-Web documents without separate chapters. They were also concerned that by incorporating WCAG 2.0 by reference, conformity assessment would become a single check-off item in that agencies would not ensure compliance with each success criteria unless they were specifically laid out in the regulatory text. Ten commenters (four disability advocacy organizations, three academics, two individuals, and one ICT company) generally supported applying WCAG 2.0 to non-Web content. One of these commenters explained that referencing WCAG 2.0 as a whole is not problematic because as a single standard, one must comply with all of the provisions to comply with the standard. This commenter explained that there is much overlap between Web and non-Web content, for example an eBook is a document that also has Web components, software, and media. This incorporation of WCAG 2.0 for non-Web content as well as Web content allows the user to evaluate all content with one standard. 2ff7e9595c
